PDF Reader for Linux: 8 Best Linux PDF Viewers in 2026

A Linux PDF viewer should be chosen by workflow, not by the length of its feature list. A browser may be enough for opening and signing a form, while students, LaTeX users, and people editing existing text need very different tools.

I compared the current native availability, reading features, annotation workflow, form support, editing scope, and main limitation of each option. UPDF does not currently offer a native Linux desktop app, so the Linux recommendations come first; the cross-device UPDF option is included later only for readers who also use Windows, macOS, iOS, or Android.

How We Chose the Best PDF Readers for Linux

I evaluated each Linux PDF viewer against five questions:

• Is there a current native Linux build or an actively maintained distribution package?
• Can it search, navigate, print, and open password-protected PDFs?
• Does it support annotations, forms, or signatures?
• Is it a reader, an annotation tool, or a full PDF editor?
• What limitation is most likely to make a user switch to another tool?

Feature and platform claims were checked against official product documentation on September 20, 2026. Performance claims are excluded unless they can be reproduced with the same files on the same Linux device.

Which Linux PDF Viewer Should You Choose?

Top 8 PDF Readers for Linux

1. Okular — Best Overall PDF Reader for Linux

Okular is the safest default recommendation for most Linux users. It is available through the software stores of most Linux distributions and supports PDF navigation, search, annotations, forms, printing, and several non-PDF document formats. Its main boundary is content editing: annotations can be added, but it is not designed to rewrite the original text and images already embedded in a PDF.

The official Okular download page recommends installing it through Discover, GNOME Software, or the distribution's software store. This makes it easier to receive updates from the package source you already trust.

2. Xreader — Best PDF Reader for Linux Mint

Xreader is maintained by the Linux Mint project and is the natural first choice for Mint users. It handles PDF and PostScript documents, supports text search, copying, document outlines, bookmarks, password-protected files, and printing. It is a reader rather than a complete editor, which keeps the interface simple but limits advanced PDF changes.

The official Xreader project recommends installing it through the system package manager. Users searching specifically for a Linux Mint PDF reader should try the installed Xreader app before adding another tool.

3. Papers / Evince — Best for GNOME Desktops

Papers is the current GNOME Document Viewer and replaced Evince as the default viewer in GNOME 49. Older distributions may still provide Evince, so the name users see depends on their GNOME and distribution version. Treat both as streamlined readers rather than full PDF editors.

This naming difference matters when following older tutorials: a guide may say Evince while a current GNOME installation shows Papers or simply Document Viewer. The GNOME 49 release notes confirm the change.

4. Firefox — Best No-Install PDF Viewer on Linux

Firefox's built-in PDF viewer now does more than display documents. It can fill supported form fields and add text, drawings, highlights, comments, images, and a visible signature before saving a new copy. The signature is an annotation, not a certificate-based digital signature, so it should not be treated as identity verification.

Mozilla documents these capabilities in its current Firefox PDF Viewer guide. Firefox is therefore a credible default for occasional PDF work, not a viewing-only fallback.

5. Xournal++ — Best for Handwritten PDF Notes

Xournal++ uses a PDF as the background of a separate journal, making it especially useful for handwriting, highlighting, shapes, text boxes, and pen input. Its editable working file is saved separately in the Xournal++ format. When exported back to PDF, the added annotations are flattened, and built-in PDF notes or forms may not be preserved.

That limitation is easy to miss if you expect Xournal++ to modify the original PDF annotation structure. Read the official Xournal++ PDF guide before using it for a form or a document that must remain editable.

If your task is specifically adding a signature rather than general note-taking, see the separate guide to signing a PDF in Linux.

6. Sioyek — Best for Research Papers and Technical Books

Sioyek is designed specifically for research papers and technical books. Its workflow emphasizes navigating references and revisiting connected passages rather than general PDF editing. This makes it a stronger specialist choice than a basic viewer for academic reading, but less suitable for users who only want familiar menus and buttons.

The focus is stated clearly in the official Sioyek documentation. Choose it for the reading workflow, not because you expect an Acrobat-style editor.

7. Zathura — Best Keyboard-Driven Linux PDF Viewer

Zathura uses a minimal interface centered on keyboard navigation. It supports bookmarks, quickmarks, encrypted documents, search, printing, automatic reload, and forward and inverse SyncTeX navigation. PDF support is supplied through a Poppler or MuPDF plugin, so installation packages can vary by distribution.

The official Zathura project page also documents its link navigation and configuration options. It is one of the clearest choices when the PDF is an output you repeatedly rebuild from LaTeX.

8. Master PDF Editor — Best Full PDF Editor for Linux

Master PDF Editor is the most complete editing option in this shortlist. It supports Linux, Windows, and macOS and can modify existing text and objects, create and fill forms, run OCR, manage pages, and work with digital signatures. The demo has no functional restriction other than adding a watermark to output files. A single full-version license currently costs US$79.95 and includes one year of updates and support.

These terms come from the current Master PDF Editor product page and official purchase page. If viewing and annotations are not enough, also compare these native Linux PDF editors for changing text, images, and page content.

Linux PDF Reader Comparison

Need a native Linux application? Stay with the eight options above. If you also handle the same PDFs on Windows, macOS, iOS, or Android and need text editing, OCR, conversion, or page management, UPDF can cover that part of your cross-device workflow.

UPDF does not currently offer a native Linux desktop app. Download it only on a supported device; installation is free, and Pro removes the trial watermark from exported files.

Where UPDF Fits in a Linux-Centered Workflow

UPDF should not be presented as a Linux PDF reader. It is relevant when a Linux user also owns a supported Windows, macOS, iOS, or Android device and needs capabilities beyond native Linux viewers, such as editing existing text and images, OCR, conversion, redaction, or page organization.

For example, you can read and annotate a file with Okular on Linux, then perform a larger content edit with UPDF on a supported device. If Linux is your only operating system, choose a native Linux tool from the comparison above instead.

Use UPDF on a supported device to edit or OCR the file. Installation is free, and Pro removes the trial watermark from exported files.

FAQs About PDF Readers for Linux

Conclusion

Okular is the best starting point for most people looking for a PDF reader for Linux. Xreader is the natural choice on Linux Mint, Papers fits current GNOME desktops, Firefox handles quick no-install viewing and markup, and Xournal++ is better for handwritten notes. Sioyek and Zathura serve more specialized research and LaTeX workflows, while Master PDF Editor is the strongest option here for editing existing PDF content.

If your PDF workflow extends beyond Linux, use UPDF on Windows, macOS, iOS, or Android for editing, OCR, conversion, and page management. Installation is free, and Pro removes the trial watermark from exported files.
