Now we will look at how to compress PDF files, because this format is gaining more and more fans, but due to its features, which will be discussed later, it can take up a lot of space. We will try to solve this problem.
The essence of the problem
To begin with, a PDF file allows you to create and store various documents in a convenient electronic form (including e-books and presentations). In addition, the specified format allows you to prepare materials for printing. Files of this type, as a rule, consist of graphics and text.
The document may contain images in vector or raster formats, as well as multimedia inserts. Also, the extension supports the implementation of various fonts. Because of this, the resulting PDF file can be very large.
Compress PDF for free
To fully work with PDF, a developer of this format called Adobe Systems recommends using the Acrobat Pro program. The main disadvantage of this application is the high price. Most often, the user will have enough features that provide free counterparts. The first answer to the question of how to compress PDFs is efficient and simple.
When creating a file, use the standard reduction features. For this purpose, open “Properties”, then go to the “General” item, and then “Other”, check the “Compress” function with a tick.
Using PDF Compressor
PDF Compressor can also tell us how to compress and work with PDFs. The application has a convenient user interface. It features high speed. It is possible to significantly reduce the size of the document, while eliminating the loss of page quality.
The program allows you to use batch processing of files, and in addition, create a queue for future compression. Upon completion of page processing, the tool shows the elapsed time, as well as the degree of compression. The program is compatible with any current version of Windows.
How to compress PDFs: other options
In some cases, in order to reduce the size of the document, you need to delete pages that do not contain important information. This task is easy to accomplish using the PDFtk application, which is also free.
The user needs to open the file using the program, double-clicking on the right column, and then specify the numbers of those pages that should be included in the finished document. All that remains is to use the Create PDF function. Thus, a file appears that will contain only the specified pages.
If the document needs to be sent by e-mail, in the same way you can divide it into several separate parts. The program has a graphical interface, as well as a console line.
Remember that vector graphics, by definition, take up more space in a file than raster graphics. If you rasterize vector images and paste them into a PDF, while reducing resolution and setting compression quality, the file size will be significantly reduced.
The PrimoPDF program can also help us. The application installs a virtual PDF printer. In order to reduce the volume of the PDF file using the program, we perform a series of actions. We open the document with any application intended for these purposes. In the menu called “File”, select “Print”, assign “PrimoPDF” as the print medium.
We go into the settings, set the required quality. We save the file on a personal computer. It should be noted that the application does not require registration from the user, and does not contain advertising.
There are also a number of online services with which you can achieve the desired result. The most famous is a quick and convenient project from foreign developers called SmallPDF.
