PDFelement-Powerful and Simple PDF Editor
Get started with the easiest way to manage PDFs with PDFelement!
Linux is an operating system like Windows and macOS, and Ubuntu is a modern operating system (OS) based on Linux. Some people prefer it because it is an open-source OS. Many programs working on Windows also work on Linux/Ubuntu. However, not all of them do. So, the PDF Reader you use on Windows or Mac may be unavailable.
A PDF reader is a tool everyone should have on their computers. It's a handy tool for either school or business. You'd want the most reliable one installed on your computer. Here are the six (6) best PDF readers for Linux (Ubuntu 20.04 included).
1. Adobe PDF Reader Linux
Adobe PDF Reader did not have Linux support before, but it's now available. If you switched from Windows, you already know how fantastic this tool is. Adobe PDF Reader is a free tool providing you with all the necessary tools. Users who left reviews about this product say they love the password-protecting, viewing, and printing features. But please note that it does not have PDF editing features. Adobe has a separate program for that.
Adobe Systems is the creator of the PDF file type. So it knows what it is doing when it comes to PDF readers.
It is free.
It has all the necessary tools for PDF viewing, printing, and commenting.
While the user interface is simple, it is not very user-friendly.
Slow at loading large files.
2. Okular PDF Viewer for Linux (Ubuntu 20.04 Supported)
Okular is a document viewer that allows you to open PDFs and also supports other common file types like Postscript, DjVu, CHM, XPS, and EPUB. Another great thing about this universal reader is the Night Mode option. That allows you to read better in low-light levels. On top of that, Okular supports annotations, which it calls "Reviews." And you know what? This is a free PDF Reader for Linux!
Okular's memory usage may turn you off, but there's an easy fix to that problem.
It's a universal document reader, so you can also use it to view other files that are not PDF.
Okular has all the tools you would want on a document reader.
It has a pseudo "Night Mode" feature.
It is free.
Okular is very memory-hungry. It will eat 1.5 GB RAM on a 4 GB RAM computer. Even if you minimize Okular or leave it idle for hours, the memory it uses will not be freed. That may slow down your computer.
3. Foxit Reader Linux
Foxit Reader is another multi-platform PDF reader that is potentially already familiar to you. It allows you to open PDFs by double-clicking them. Also, it shows you the thumbnails of every page. What sets it apart from the open-source PDF readers for Linux is the customizable toolbar. It makes it easier to find and click tools you often use. Another advantage is its higher picture quality; it applies anti-aliasing to images, making them look sharper and more visually striking.
Foxit Reader has every tool a PDF viewer should have and even includes some basic editing features.
It has better picture quality than the free PDF viewer that comes with Gnome-based Linux systems.
Foxit Reader is a lightweight program, so there are not many system requirements.
Foxit is closed-source software, and the main interface has advertisements. Linux users may find this annoying.
Some features are locked behind a paywall, while there are free alternatives.
The only way to install Foxit Reader is by downloading and installing the .deb file you can find on its website.
4. Master PDF Editor

On top of that, you can annotate, add watermarks or background images, add headers and footers to PDFs, and more. Needless to say, some of these features are available only on the paid version of Master PDF Editor.

6. Zathura PDF Viewer
Zathura is a free, lightweight, and fast document viewer you can use to view PDFs on Linux/Ubuntu. You use a keyboard to use this program since it requires you to use keyboard shortcuts to operate it. The keyboard shortcuts for Zathura are similar to the shortcuts for the text editor vim.
