5 Best Free PDF Readers and Viewers for Windows

Best PDF Readers and Viewers Software for Windows for Viewing/Reading, Basic Editing, and Annotating PDF Documents

PDF (.pdf) is an acronym for Portable Document Format. It is the most popular document format.

There are a number of reasons behind the dominance of the PDF file format. One of the most important ones is its ability to create password-protected documents. There are various security-related features supported by the PDF file format such as password-protection, digital signatures, certificates, etc.

Another one is that it uses only one file extension, unlike other document file types. Various word processing applications use their own file formats for their software such as .docx, .pages, .odt, etc. That’s not the case with PDF, which uses a universal file extension, .pdf.

Then, there is the benefit that is mentioned in its name itself, portability. A PDF document is a locked document. The fonts used, the formatting of that document, and other settings are locked when you create or export a PDF document; it also has the ability to embed fonts, so if the receiver of the PDF file does not have the fonts used in it, the computer will still display the correct fonts.

Most of the web browsers integrate a PDF reader/viewer component into them. They have support for viewing and creating PDF files. Microsoft supports PDF viewing through their Edge browser, it has more features than any other major browser. So, out of the box, you have some ability to view your PDF files.

However, the PDF components available in Web browsers don’t give you the same level of control that a third-party dedicated PDF application can do.

Features Required in an Ideal PDF Reader/Viewer

  1. Rotate – This is the most basic and the most important features required in a PDF viewer/reader. When you create a PDF from your images, or from online resources such as websites, sometimes the PDF may display the content in the wrong direction. You can prevent this situation from happening in the first place by rotating and saving the images, but if that it too much then you can always use your PDF viewer/reader to do this provided your software supports this feature.
  2. Shuffle – Shuffle means rearranging the pages inside a PDF. You may want to exclude a page from your PDF file, and then save it. The Shuffle feature lets you configure the order of pages. It is provided as a premium or paid feature.
  3. Snapshot – Taking a Snapshot is the ability to take screenshots of specific sections in the PDF file, and then save those selected sections as separate images. It’s a great way of storing the essential information from a PDF file. It is very productive as well as you don’t have to open your PDF viewer/reader, and navigate to the specific page to get access to the required information; just take Snapshots and store as images.
  4. Text Select – As the name suggests, the Text Select feature lets you copy the text from a PDF file, and paste it in a text editor such as Notepad. This is another way of extracting only the most relevant information from a PDF file.
  5. Highlight – You may want to highlight an important section of a text in your PDF files. Unlike text editors, you cannot Bold the text contained in a PDF file. Your only avenue is to highlight the important section just as you would do on a paper using a marker.
  6. PDF Printer Support – Some time ago, this feature was used as a standalone feature to create a dedicated software. Now, it is available as a component in some of the web browsers such as Chrome. Many feature-rich PDF viewer/reader now include this feature as well.
  7. Font Support/Compatibility/Embed Fonts – A decent fall-back font should be used if the font used at the time of PDF creation is not available on the system of the person receiving and viewing the PDF.
  8. Extract Pages as PDF Images – This lets the user extract selected pages from a PDF file to the supported images formats. It is provided as a premium or paid feature.
  9. Add Pages to/Delete Pages from Existing PDF files – Another one of those premium or paid features. This lets you delete the unwanted pages, or add new pages to update the PDF file.
  10. Essential Shortcut Buttons – This is related to the User Interface and User Experience of the software. The shortcuts to the most essential features such as Go to (Page Number), Zoom, View, should be provided as Buttons in Taskbar, Status Bar, and other Toolbars of the software.
  11. Security – Password protect, and open password protected. It should have the ability to open a password-protected document by entering the Another security feature that some users may want is the ability to digitally sign a document, and to recognize any changes made to the original digitally signed document.
  12. Additional File Format Support – Additional file format support for various kind of eBooks such as .mobi, .epub, .chm, etc. is always a great help. This is kind of a bonus. There are dedicated software that do more than just open these files. However, if you are just a casual ebook reader, it would be nice to have a PDF viewer/reader that is able to read them.

Four Foxit Reader Creator plugins for Microsoft Word, Excel, and PowerPoint are included. A Windows shell extension (context menu) for converting files to PDF is listed as well.
