How to shrink a pdf file in adobe reader. How to reduce the size of a pdf file: compression methods and volume reduction. Method for reducing file size in Adobe Acrobat, using the PDF optimizer

PDF files are quite in demand today, but often they are too large, that is, they take up a lot of space. If you are not satisfied with the size of the document, you can reduce it in several ways.

You can reduce the size of a PDF file using a special converting program. There are quite a few such services, let's look at the example of the free PrimoPDF program. Download the service to your computer. It will install a PDF printer on your system that will convert the files. You can also use the CutePDF program. When you install it on your computer, a print function will appear that allows you to save files in PDF format. First, open the PDF document in the "reader" you are using. Select "File", "Print" from the menu. Specify the converter as the device for printing (for example, PrimoPDF).

Click on "Properties", select the option to reduce the size of the document while maintaining its readability. In different applications, this option may be called differently, but it must be present. For example, in PrimoPDF, select "Screen". At the same time, the quality of the text will decrease significantly, it will be available only for reading (not for printing). In CutePDF, you need to open the "Compression" tab, then select the quality.

After that, all that remains is to save the file. To do this, click "Print", "Save As", specify the location of the document.

Consider the second way to reduce the size of a PDF - using online services. There are many free tools available on the Internet: SmallPDF, Neevia's PDFCompress, and others. In the first case, the number of processed files and their size are not limited, in the second case, the document should not exceed 5 MB, but there are additional functions and opportunities. To reduce a file in SmallPDF, you just need to drag it to the specified location or select through the existing button. After downloading, the document will automatically begin to compress, which may take several minutes depending on the initial file size. The processed document will simply be saved by selecting a location on your computer. But it should be understood that not every file can be optimized. If it's already compressed, you'll get a message that additional compression is not possible. The third way you can compress a PDF is with the special "reduce size" command in Adobe Acrobat. Click Save As from the File menu ( given function absent in free version). In the additional menu that appears, select Reduced PDF Size. You can also do this through the Documents menu. It is important to choose the correct version of Acrobat, otherwise a document processed in a more recent version will not be able to open in the previous one.

If you plan to use the selected save options for multiple files, click the Apply to Multiple Files button. You can then add the following documents. When saving, specify the name of the file, its location.

The fourth method involves using the built-in Windows compression function. Documents are converted to a ZIP (RAR) archive, but they are not significantly compressed. This option is suitable if you need to compress several files into a single archive. Of course, you can download other programs, but then if you decide to send the file to someone, the recipient must also have this program to open the file.

PDF is a convenient format for working with texts that supports many graphic elements. Such data submission method very clear and informative, but many documents of this format have a large volume, which makes it difficult to transfer them over e-mail. To facilitate this process, pdf (pdf) files are compressed, that is, they reduce the original size.

Compressing a document is quite easy: there are various programs and online services for this. It must be mentioned that pdf is a cross platform format, thus, it can interact with different operating systems (OS) and devices.

File size reduction question pdf format often set by an active computer user. Due to the large weight of the scanned images. Because of this, the document takes up hundreds of megabytes of disk space. Let's consider the problem in more detail.

With Adobe Reader

You can reduce the size of a document using the free version Adobe software Acrobat Reader. The compression feature is only available at checkout paid subscription. The utility is installed without problems, so let's get to work right away.

From the start menu, go to the “File” tab. Click on the “Open” item and select the document. In this example, we will use a 69.9 MB textbook. It consists entirely of scanned pages of the printed edition. You can also open a document by clicking on it. file manager. Go to the menu shown in the screenshot.

We leave the default values in the called window. Choose a location to save the compressed pdf. The example file now weighs 33.3 MB. Compression was performed for about two minutes. The image quality has deteriorated. On a website or computer, this may not be noticeable. However, after printing, the illustrations will be fuzzy or completely blurry. The disadvantage of this method is that there is no flexible setting for an advanced user.

If installation is required additional options, the optimizer will help. We open the document we need. Click on the button shown in the illustration below.

There are few settings, but they look difficult to master. Let's define the main ones. They are located in the left menu "Images". Downsampling determines the resolution of images. To the right of the parameter, you can set ppi (number of pixels per inch). Highly recommended for printing. It is advised when placing illustrations on the site. Below you can set the type of compression. ZIP is used for simple images dominated by one color. JPEG - for any images. Its improved version is JPEG2000.

After setting, choose a location to save the file. Let's compare the quality of the optimized document and the original. Left - original file, right - compressed.

Changes in quality are imperceptible even when the picture is enlarged three times.

Using third party software

For the role free analogue suitable PDF Compressor.

During the compression process, the weight of the textbook from the example decreased from 69.9 MB to 56.9 MB. Compare quality. On the left - the document before optimization, on the right - after.

The result is worse than Adobe Acrobat Reader. Now the compressed file is distorted. The advantage of the program is that you can compress the file absolutely free. As a result - the worst quality and larger size. The utility logo is also added to the first page.

With WinRAR

winrar- free program with the option to purchase a license. Designed to place files in an archive and then compress them. The quality does not change. You can extract the original from the archive at any time.

The workspace of the utility shows file system your computer. Select a folder to create the archive. Click on "Add". The button is on the left upper corner. Before us is the archive settings menu.

We are interested in the drop-down list “Compression method” in the “General” tab.

Their names speak for themselves. High-speed less time-consuming, also having a low compression ratio. The maximum has the opposite characteristics.

Documents are added from the Files tab.

The compression of the file from the example took several seconds. The file weight has changed from 69.9 MB to 68.3 MB. Conclusion: WinRAR does not work well with pdf files. Plus program - the original is preserved unchanged.

Using the online service ILovePdf

After the compression process, we get to new page and press the big red button again.

In the screenshot above, we were also informed about changes in the weight of the document. Instead of 69.9 MB, the textbook now weighs 55.9 MB. The result is similar to that of the PDF Compressor application. The difference is that you do not need to download or install anything. Compare quality. On the left is the optimized document, on the right is the original.

A slight loss of quality is noticeable, the perception of information is not affected.

Click on the big red button. You don't need to click anything to reduce the size of a pdf file. It happens right after loading. Then download the document by clicking on the “Download file” button.

From the service, the document can be sent to Google Drive or DropBox (neighboring buttons). The illustration shows the volume of the compressed document. The file size has changed from 69.9 MB to 59.2 MB. A little more than the previous service. Let's check the quality. Left - compressed pdf, right - original.
