5 Free PDF Viewers and Editors for Android, iOS & Windows

Free PDF Viewers
Written by Hassan Abbas

Most users have enough free features. Those who are not comfortable with the restrictions can pay.

For convenience, we select four types of programs: viewers (for reading and annotating), editors (for editing text and other content), managers (for staking out, compressing and other manipulating files) and converters (for converting PDF to other formats).

Most applications can be attributed directly to several types.

Free PDF Viewers

Sejda PDF

  • Platforms: Windows, macOS, Linux.

Very intuitive and convenient program with an impressive number of functions. By running Sejda PDF, you will immediately see all the tools grouped by category. Choose the right one, drag the desired file into the program window and proceed with the manipulations. Most PDF actions in this application can be performed in a few seconds, even if you are using it for the first time.

PDFsam cannot boast a polished to perfection, user-friendly interface. In addition, the program does not allow you to convert PDF and edit the contents of documents for free. But it has several useful managerial functions, available to all without payment and no restrictions.
