word-sys PDF Editor

word-sys PDF Editor is a free and open-source desktop PDF editor for Linux, built in Python with GTK 4 and PyMuPDF. It was developed for Pardus, Debian and other Linux distributions and won first place in the TEKNOFEST 2025 Pardus Development Competition. Where most free Linux PDF tools only view, annotate or rearrange pages, it focuses on directly editing the content of a PDF: you can select and modify existing text blocks, delete text, add new text, insert images with alpha transparency, move objects, and change font type, size, color and decoration.

Beyond content editing, it covers the everyday PDF workflow: create PDFs with custom page dimensions, open and view documents in tabs, merge PDFs, add rectangles, ellipses, checkmarks and crosses, draw freehand pen and highlighter strokes, and add, remove or reorder pages with drag-and-drop thumbnails. Multi-level undo/redo, Safe Save, a Restricted Mode, and an interactive quick-start guide (F1) round it out. A built-in pure-Python engine called anyconvert exports PDFs to DOCX, PPTX, ODT, ODP and TXT without LibreOffice, in either pixel-accurate canvas mode or semantic flow mode.

For anyone replacing Adobe Acrobat, Foxit or Nitro on a Linux machine, the pitch is simple: it is completely free under GPL-3.0-or-later, installs from a .deb package, AppImage or AUR, and handles the most common paid-editor jobs — text and image editing, merging, annotating and format conversion — without subscriptions or vendor lock-in. The companion anyconvert CLI is also available on PyPI for scripted conversions.
