How to reduce file size in a scanner. How to reduce the size of a pdf, detailed instructions. Using the SmallPdf online service

23.10.2023 -

Having received today from a person whose abilities I do not doubt at all, and who is no stranger to computers and the Internet, a letter with an attachment of three scanned documents weighing a total of 38 megabytes,

I decided to tell him step by step how to reduce the files resulting from scanning.
And then I thought that this would probably be interesting and useful to someone else.

And the link to this page can henceforth be given to people - without additional explanation - when receiving multi-megabyte letters from them.
Something like this:
“Oh, by the way, I came across a page on the Internet here, I think you will be interested: "

So. Let's get started...
Warning: I think that most of my readers will not be interested in this entry and will not provide any new information.
Don't say I didn't warn you ;-)

0. You should start with this that many scanner control programs allow you to customize the quality and size of the output file, as well as its format.
In 99.99% of cases, the JPG format will be enough for you, size 1200 * 1600, DPI = 300, in other cases: 2400 * 3200, corresponding to the size of an A4 sheet
But, if it was not possible to configure it in the scanner, then the guide below will help us solve everything.

1. So, we have a file scanned from an A4 page.
We set the TIFF format (either our not very new scanner refuses to save files in other formats, or resets our settings every time, or works quickly only by saving in TIFF) - I have encountered all of the above cases and all of them can be overcome.
The resulting file weighs a terrible 26 megabytes.

2. Open it in the IrfanView program.
I recommend this program because I've been using it to view images for over 12 years. It is free for non-commercial use and supports many convenient plugins. It is best to download it from the official website.

4. and select the format - JPG

5. Set the file quality 85% - in most cases this is more than enough, and this indicator greatly affects the final file size

7. We can stop here, but if the file we send will only be viewed on the monitor without printing, or printed without the need to maintain high quality, we can further reduce the file. It will take a minute.

We press the key combination Ctrl + R or select “resize image” from the menu:

and reduce the image size:

After which the “weight” of the file became very small compared to the initial one, less than 1 megabyte

We can stop here completely.

I will add that depending on the purposes, the size and weight of the file can be changed in a very significant range.
Experiment!

If you need to increase the disk space on your device or simply change the weight of an image, you need to know how to reduce the size of a jpg file.

This photo format is the most common.

JPG compression is supported by all devices and allows you to save image information without loss or distortion.

The weight of a jpg file can be found in the photo properties, and the volume of the picture can be easily changed using editing programs and online services.

Method No. 1. Reducing the size of a picture in Paint.NET

Paint is the simplest standard program for editing raster and vector images. Available for all users of Windows operating systems.

Main tools available in the application:

adding inscriptions;
filling elements;
trimming, pasting;
copying fragments, etc.

After changing the width and height of the photo, the size changes.

Follow the instructions to reduce the size of the Paint image:

Right-click on the desired image and select Edit. The photo will automatically open in Paint in editing mode;

On the main toolbar, find the resize button and click on it. A dialog box will open. To reduce the size of the final file, you need to change the size to a smaller one.
You can edit using percentages or pixels. By saving, you will reduce the size of the image.

Remember! After changing the width parameter, you need to change the height proportionally. Otherwise, the picture may become too stretched and disproportionate.

Method No. 2. Resizing in Photoshop

The photo file size can also be reduced in a professional raster image editing program - Photoshop. Follow the instructions:

Open the application and import the required graphic file for further work;
Find the Image tab on the main toolbar, click on it. Select Image Size from the drop-down list, as shown in the figure below;

Change the image dimension parameters (width and height), and also make sure that the checkbox next to Maintain photo proportions is checked;

Try reducing the photo by 10-15 percent. Thus, its final weight will also decrease.

Method number 3. Using MS Office programs

The test Word processor version 2010 and earlier versions have an image compression function. This function has been removed in the latest versions of the program.

Add a picture to the document page, then in the tab that appears, select “Open with”, and then the MS Picture Manager application.

In the window that opens, click on the “Image” tab and select “Compress image”. The higher the compression ratio, the smaller the final file size will be.

Save the resulting changes.

Important! After compression, the quality of the illustration may deteriorate.

Method number 4. Using online services

An excellent web service for working with photos is the resource irfanview.com. It allows you to work with a huge number of different image formats.

To reduce the size, you can open the image menu and edit its height and width.

Also in the resizing window, you can select additional parameters for better compression: sharpening, sharpening filter, special keys for reducing/increasing the size and changing the image resolution.

The saving option can also reduce the size. The best option for setting them up is shown in the figure below.

This window appears while the final image is being saved.

Method No. 5. Reducing size on Mac devices

A free application for working with pictures and photos called iPhoto is available for Mac OS users.

If the program is not installed on your device, download it from the official store. It's completely free.

The utility allows you to easily work with images of all currently common formats.

Click on the events tab twice;
Select the required picture;
In the settings window, adjust the photo size: you can adjust the width, height and resolution. The lower these parameters, the correspondingly lower the file size;
Save the image.

How to quickly compress a PDF file

There are three ways to download a file: drag and drop with the mouse, specify the path on your hard drive, or download from the cloud.

You can also convert a color document to black and white, which will reduce the size of the PDF file.

Compress PDF file online

There is no need to download or install anything - process PDF files in the browser in any place convenient for you.

PDF2Go Online Studio is a free and secure alternative to offline programs for processing PDF documents. With this tool you can downsize images and compress files.

Why compress PDF files?

When uploading files online or sending via email, one important thing to keep in mind is size. The PDF format is widely used for resumes, all kinds of documents, and even homework.

A PDF compressor allows you to download and send even those files that may seem overwhelming.

Secure file compression

When you upload files to PDF2Go, you don't have to worry about security. We guarantee confidentiality and protection from unauthorized access. All operations are performed automatically, and copyrights remain with you!

See Privacy Policy for details.

What files can be compressed?

Compress PDFs on any device

You don't need a computer to compress a PDF file. Mobile studio PDF2Go is convenient and pleasant, like “coffee to go”.

Whether it's a smartphone or tablet, Windows or Mac, Firefox or Internet Explorer - PDF2Go will help out in any situation.

PDF files with lots of graphic elements look nice, but sending them by email is a complete pain due to the large size of such documents. There is no need to wait long for the file to be attached to the letter, because you can reduce its size with virtually no loss of quality. Fortunately, there are plenty of ways to do this - choose whichever you want.

It is worth noting, however, that half of the methods listed below are only possible using Acrobat DC from Adobe installed on your PC. This is a paid product, but the 30-day trial version is completely free. It is available on the official Adobe Systems website.

Using CutePDF or another PDF converter

You can reduce the size of a PDF file using one of the converters, for example, CutePDF. It allows you to convert files from any printable format to PDF, as well as change the document size, increasing or decreasing the quality of images and text. When you install this product, a virtual printer is created on the system, which, instead of printing documents, converts them to PDF format.

1. Download CutePDF from the official website (free) and install. Don’t forget to install the converter along with it, otherwise nothing will happen after clicking the “Print” button.

2. Open the file in a program that supports its format and has the ability to print documents. If it's a PDF file, you can open it in Adobe Reader; and if the file is in doc or docx format, Microsoft Word will do. Click on the “File” menu item and select “Print”.

3. When the printing settings window opens, select CutePDF Writer from the list of printers.

4. Click on the “Printer Properties” button, in the window that opens, click on the “Advanced” button and select the content display quality. To compress the file to the desired size, select a quality lower than the original quality.

5. Click the “Print” button and save the file to the desired location. Only PDF is available for saving, regardless of what format the document was originally in.

Using online tools

If you don’t want to download and install anything, then you can compress the PDF file online. Compressing and converting documents online is fast and convenient.

1. Find a suitable tool on the Internet, such as Smallpdf. Unlike other similar online tools, here the user is not limited in the size and number of documents he can upload.

2. After visiting the website, upload the required document. This can be done by clicking on the label and selecting the file using Explorer, or by dragging the file with the left mouse button and dropping it in the desired area. You can also add a document from Dropbox or Google Drive.

3. When the process is complete, click on the “You can save the file” button and select a location on your PC for it. To upload a compressed document to Google Drive or Dropbox, click the corresponding icon on the right side of the button.

In addition to Smallpdf, there are many other online compressors on the Internet: Compress PDF, Online2pdf, PDFzipper and others. Some allow you to upload files up to 50 MB in size, others - up to 100 MB, others have no restrictions at all, but they perform their work at approximately the same level.

In Adobe Acrobat

You can compress a PDF file in Adobe Acrobat DC, but not in the free Adobe Reader.

1. Having opened the document in Acrobat, click on the “File” menu item, then select “Save as another” and click on the line “Reduced PDF file”.

2. Click in the drop-down list on the version of the program with which your document should be compatible. By choosing the newest version, you can compress the file as much as possible, but there is a risk that it will become inaccessible in previous versions of Acrobat.

3. Click on the “Ok” button, wait for the compression process to complete and save the compressed document to the desired location.

Another PDF compression method in Adobe Acrobat DC

If you have Adobe Acrobat installed and need to compress a document located on your PC, it is much more advisable to use the previous method. The same method can be used when the desired file is uploaded, say, to Google Drive, and you need to download it, simultaneously reducing its size.

1. Log into Google Drive from your account, double-click the PDF file you want to compress, and click the printer icon to open the print screen.

2. In the window that opens, click on the drop-down list and select the Adobe PDF line.

3. By clicking on the “Properties” button, you will open another window where you need to select the “Paper and Print Quality” tab, and then click on the “Advanced” button at the bottom of the window.

4. In the drop-down list (see screenshot below), select the desired document quality, at the bottom of the window click on the “Ok” button, then in the next two windows also click on “Ok”.

5. Save the reduced file on your PC.

Using Adobe Acrobat and Microsoft Word

The essence of this method of compressing PDF documents is that you first convert the file from one format to another, and then convert it back.

1. Open the PDF document through Adobe Acrobat, go to the "File" menu and select "Save As".

2. Click on the “Select another folder” button, then select the file type “Word Document (*.docx)” and save location. Click on "Save".

3. Having opened the document in Microsoft Word, click on the “File” item and select the “Save as Adobe PDF” sub-item.

Using PDF Optimizer

This method of reducing the size of PDF files also requires the use of software from Adobe Systems.

1. Open the document you want to reduce using Adobe Acrobat. Next, go to the “File” menu, click on the “Save as Other” line and select “Optimized PDF File” to launch the PDF document optimizer.

2. In the “PDF Optimization” window that opens, click on the “Estimate space usage” button to understand which elements take up how much space in the file (in bytes and percentage).

3. Having assessed what can be reduced and what does not make sense to compress, close the window by clicking on the “Ok” button and set the necessary compression parameters. To do this, in the left part of the window, left-click on one or another item, and in the right part, change the parameters.

4. You can delete images, change them from color to black and white, compress them, change resolution, change built-in fonts, etc. Having “played enough” with the parameters, click on the “Ok” button and save the optimized file to the desired directory.

A way to compress PDF files on Mac OS X

PDF documents created by the Mac OS X operating system are noticeably larger in size than files with the same content created using Adobe Acrobat. If you are a Mac OS X user and want to reduce the size of the PDF file you create, do the following:

Open the TextEdit application, then click on “File” in the program menu, and then select “Print”.
In the lower left corner of the window that opens, you will see a button called PDF. Click on it, and then on the line “Compress PDF” in the drop-down list. The result is a more compact PDF file.

Archiving a file

To ensure that the document takes up less space on your computer, you can archive it using one of the archivers, for example, 7Zip or WinRAR. Both programs are quite popular, but the first is distributed free of charge, and you will have to pay to use the second beyond the limited trial period.

To compress a document using the 7Zip archiver, right-click on the file, then with the left mouse button, first click on the 7Zip line, and then on the inscription “Add to “file_name”. Then the archive will be created automatically.

If you want to set certain parameters before archiving, select the “Add to archive” line. Then a window like the one in the screenshot below will open.

By using an archiver, you can significantly reduce the size of a document, as well as create an archive consisting of several files, compressed and combined with each other. This will make it much easier to store and transmit them via email. Just before sending an archived PDF file, make sure that the recipient also has an archiver installed, otherwise he will not be able to open the archive.

Note: Adobe Acrobat and Adobe Reader are not the same thing. Reader is free, but its range of functions for editing PDF files is extremely limited, so you can only reduce the size of documents in Acrobat. However, Adobe Acrobat is a paid program. And if you don’t have it and don’t want to buy it, use other options for compressing PDF documents that are not associated with it.

If you are faced with the task of how to reduce the size of a JPG file, then let's try to figure out this situation together. Very often, the image size needs to be reduced so that photographs or pictures do not take up much disk space. Many users often send a large number of photos by email, but as a rule, all mail servers have a limit on the amount of information in one letter.

Because of this, many people are unable to send images in an email, thereby falling into a stupor and not knowing how to get out of the situation. Also, if you upload image files to a cloud service or transfer them over the network, this will happen faster if the image has a small weight. Therefore, files must be reduced in size while trying not to spoil the image quality.

What is a JPG file?

JPEG(pronounced "japeg", English: Joint Photographic Experts Group)– the most popular raster image format. Files that contain images have the JPG extension

If you pay attention, the names of many graphic images on your computer look like (“photo title”.jpg or “photo title”.jpeg). The .jpg extension is the most popular.

JPG files are perfectly compressed, both with and without loss of quality. Accordingly, it all depends on what the user wants to get as a final result. There are a huge number of programs and online services for compressing images. Therefore, let's look at how to reduce the size of a JPG file using different methods and programs.
