The PDF format is used to store electronic documents. Initially, only a program from Adobe itself was used to open PDF files. But over time, many solutions from third-party developers have appeared. These apps vary in their availability (free and paid) and additional features. Agree, it’s convenient when, in addition to reading, there is the ability to edit the original content of a PDF file or recognize text from a picture.
Therefore, there are a large number of different programs for reading PDF. For some, a simple viewing function is enough. Others need to change the source text of a document, add a comment to this text, convert a Word file to PDF, and much more.
When it comes to PDF viewing, most programs are very similar. But there are exceptions here too. For example, some have an auto-scroll feature, while others do not. Below is a list of the most popular free PDF viewers.
The most famous program for viewing PDF files is Adobe Reader. And this is no coincidence, since Adobe is the developer of the format itself.
This product has a pleasant appearance and standard functions for viewing PDF. Adobe Reader is a free app, but some features, such as text editing and recognition, are only available if you purchase a paid subscription.
This is undoubtedly a disadvantage for those who need these functions, but do not want to spend their money.
STDU Viewer
STDU Weaver positions itself as a universal combiner for viewing many different formats of electronic documents. The program is able to “digest” Djvu, TIFF, XPS and much more. The number of supported formats also includes PDF. It is convenient when one program is enough to view a variety of files.
You can also note the presence of a portable version of STDU Viewer, which does not need to be installed. Otherwise, this product does not stand out among other PDF viewers.
Foxit Reader
Foxit Reader is almost an analogue of Adobe Reader, with the exception of some differences. For example, the program has the ability to enable automatic scrolling of document pages, which allows you to read a PDF without touching the mouse or keyboard.
The program is also capable of opening not only PDF, but also Word, Excel, TIFF and other file formats. Opened files can then be saved as PDF.
At the same time, the disadvantage of this application is the inability to edit the source PDF text.
PDF XChange Viewer
PDF XChange Viewer is probably the best program presented in this article. It is completely free and allows you to edit the original PDF content. PDF XChange Viewer is also able to recognize text in an image. Using this feature, you can convert books and other paper text into digital format.
Otherwise, the application meets all standards of software solutions for reading PDF files.
Sumatra PDF
Sumatra PDF is the simplest program on the list. But that doesn't mean she's bad. In terms of viewing PDF files, it is not inferior to others, and its simple appearance is perfect for those users who have just begun to get acquainted with working on a computer.
Solid Converter PDF
Solid Converter PDF is a program for converting PDF to Word, Excel and other electronic document formats. The application allows you to preview the document before converting. The disadvantages of Solid Converter PDF include a shareware license: you can use it for free only during the trial period. Then you need to either buy it or reinstall it.
