The Best PDF Editor for Ubuntu (22.04/24.04 LTS and GNOME)

Why Ubuntu Doesn't Ship a Built-In PDF Editor

Ubuntu's default installation includes a PDF viewer (Document Viewer / Evince, or Papers on newer GNOME releases) but no full editor. Viewing, form-filling, and light annotation are treated as separate concerns from document creation in the GNOME ecosystem, which is why LibreOffice — Ubuntu's default office suite — becomes the de facto editor for many users through its Draw module.

That gap has been filled by a mix of open-source desktop apps, self-hosted web tools, and commercial Linux-native software, each installable through Ubuntu's three main packaging systems: apt (deb packages from Ubuntu's repositories or PPAs), snap (Canonical's sandboxed format, preinstalled on Ubuntu), and flatpak (via Flathub, popular for GNOME apps but requiring one-time setup).

The Best PDF Editor for Ubuntu: Top Options Compared

LibreOffice Draw

LibreOffice Draw opens a PDF as an editable object-based document, letting you move text boxes, images, and shapes. It's already installed on most Ubuntu desktops, or reinstallable with: sudo apt install libreoffice-draw. It handles simple layouts well but tends to mangle complex, text-heavy PDFs by breaking paragraphs into disconnected text frames.

Okular

Okular is KDE's document viewer, but it runs fine under GNOME and includes solid annotation tools — highlights, freehand drawing, stamps, and form filling. Install it with: sudo apt install okular, or via flatpak: flatpak install flathub org.kde.okular. It's a viewer-plus-annotator, not a layout editor.

Xournal++

Xournal++ is built for handwritten notes and annotations on PDFs, especially useful with a stylus on a 2-in-1 Ubuntu laptop. Install with: sudo apt install xournalpp, or snap install xournalpp. It exports back to PDF but isn't meant for editing existing text content.

PDF Arranger

PDF Arranger is a GTK front-end for merging, splitting, rotating, and reordering pages — ideal for GNOME users who want a native-feeling page management tool. Install with: sudo apt install pdfarranger, or flatpak install flathub com.github.jeromerobert.pdfarranger. It doesn't touch text or images inside pages.

Master PDF Editor

Master PDF Editor is a commercial (with a free non-commercial tier) Linux-native app offering real text editing, form creation, digital signatures, and redaction. It's distributed as a .deb or .run installer from the vendor's site rather than the Ubuntu repositories, so you'll need to download it directly and install with: sudo dpkg -i masterpdfeditor*.deb.

Stirling PDF

Stirling PDF is a self-hosted, browser-accessed toolkit covering merging, splitting, compression, OCR, watermarking, and more. On Ubuntu it typically runs via Docker: docker run -d -p 8080:8080 stirlingtools/stirling-pdf:latest, after which you access it at localhost:8080. It's powerful but adds a maintenance burden — updates, container management, and local network exposure to think about.

Firefox and Chrome Built-In Viewers

Both browsers ship on Ubuntu with built-in PDF viewers (PDF.js in Firefox, PDFium in Chrome) that support basic form filling, freehand drawing, and adding text — no install needed. They're fine for quick annotations but lack merging, compression, page management, or true content editing.

Installing PDF Tools on Ubuntu: apt, snap, and flatpak

Ubuntu supports three overlapping package managers, and PDF tools are scattered across all of them:

• apt — Ubuntu's native package manager, pulling from official repositories. Example: sudo apt update && sudo apt install okular pdfarranger qpdf pdftk ghostscript
• snap — preinstalled on Ubuntu since 16.04, runs sandboxed apps that auto-update. Example: sudo snap install xournalpp
• flatpak — not preinstalled on Ubuntu; enable it first with sudo apt install flatpak && sudo apt install gnome-software-plugin-flatpak, then add Flathub: flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Command-Line PDF Tools for GNOME and Scripting

Ubuntu's terminal-first culture makes CLI tools genuinely practical for batch PDF work, cron jobs, or Nautilus (Files) 'Open With' scripts:

• qpdf — install with sudo apt install qpdf; handles linearization, decryption, page splitting, and repair of malformed PDFs.
• pdftk — install with sudo apt install pdftk-java (the Java-based fork maintained for modern Ubuntu); merges, splits, and fills forms from the command line.
• Ghostscript — install with sudo apt install ghostscript; commonly used for compression, e.g. gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/ebook -o output.pdf input.pdf.
• poppler-utils — install with sudo apt install poppler-utils; provides pdftotext, pdftoppm, and pdfinfo for extraction and conversion pipelines.

When a Browser-Based Editor Beats Installing Software

Installing and maintaining native apps makes sense for daily, heavy PDF work. But for occasional tasks — merging two files, adding a signature, splitting a scanned packet — juggling apt, snap, and flatpak versions of overlapping tools adds friction, especially across multiple Ubuntu machines or a fresh install.

PDF Editor AI (pdfai2026.lovable.app) runs entirely in the browser on Ubuntu — Firefox, Chrome, or Chromium — with no package to install and no file uploaded to a server; processing happens locally in your browser tab. It covers merging, splitting, compressing, rotating, watermarking, page numbering, form filling, and adding signatures, which handles the majority of everyday PDF tasks without touching your package manager.

It's not a replacement for Master PDF Editor's redaction and true text-reflow editing, and it doesn't include OCR for scanned documents — for those, Okular's annotation tools or a dedicated OCR pipeline (like Tesseract, installable with sudo apt install tesseract-ocr) remain the better fit on Ubuntu.

Pros and Cons of Ubuntu's PDF Editing Landscape

Best Practices for PDF Editing on Ubuntu

• Match the tool to the task: use PDF Arranger for page operations, Okular for annotation, LibreOffice Draw only for simple layouts.
• Prefer apt packages from Ubuntu's repositories for stability on LTS releases; use snap or flatpak when a tool isn't packaged natively.
• Keep a backup of the original PDF before running batch Ghostscript compression, since aggressive settings can degrade image quality irreversibly.
• Use pdftk-java or qpdf in scripts for repeatable, unattended processing rather than manually repeating GUI steps.
• For sensitive documents, favor local tools (native apps or a browser tool that doesn't upload files) over web services that require sending files to a server.

Common Mistakes to Avoid

• Assuming LibreOffice Draw can cleanly re-edit dense, multi-column PDFs — it often scrambles text frames.
• Installing the same tool via both apt and snap, causing version conflicts and confusion over which binary runs.
• Forgetting flatpak needs Flathub added manually on Ubuntu before flatpak install commands will find anything.
• Using outdated pdftk (the original Java-free build) on modern Ubuntu instead of the maintained pdftk-java fork.
• Uploading confidential PDFs to random online converters instead of using local or in-browser tools that don't transmit files.

Security and Privacy Considerations

Native Ubuntu apps (Okular, Xournal++, PDF Arranger, Master PDF Editor) process files entirely on your machine, which is ideal for sensitive documents like contracts or medical records. Self-hosted Stirling PDF keeps data on your own server or machine too, but running it as a Docker container means keeping the image patched and access controlled if it's reachable on your network.

Browser-based tools vary: some upload your file to a remote server for processing, which is a real privacy consideration for confidential documents. PDF Editor AI processes files client-side in the browser rather than uploading them, which keeps the workflow closer to a local desktop tool in terms of data handling, though you should still verify this behavior for any tool before using it with regulated or sensitive content.

Expert Tips for GNOME Workflows

• Set Okular as the default PDF handler in GNOME Settings > Default Applications if you annotate frequently — it integrates cleanly with Nautilus file previews.
• Add a custom Nautilus script wrapping a Ghostscript compression command for one-click 'Compress PDF' from the right-click menu.
• Use GNOME's built-in screenshot tool alongside Xournal++ for quickly annotating and re-exporting scanned pages.
• Pin frequently used PDF tools to the GNOME dock via Ubuntu's Activities overview for faster access than searching each time.
• For multi-monitor Ubuntu setups, Master PDF Editor's dockable panels make side-by-side review and editing more efficient than single-window tools.

Conclusion: Choosing the Best PDF Editor for Ubuntu

There's no single best pdf editor for ubuntu that covers every task — the practical answer is a small toolkit: PDF Arranger or qpdf for page operations, Okular for annotation and forms, Master PDF Editor when you need real text editing, and a browser-based tool like PDF Editor AI for quick, install-free tasks across any Ubuntu machine. Match the tool to what you're actually doing, install through apt or flatpak where possible for easier maintenance, and lean on CLI tools once a task becomes repetitive.
