PDF Editor v0.1.3

First public release — a standalone, open-source PDF viewer + editor for Windows, built on PyMuPDF (engine) and PySide6 (UI).

Install

Download pdf-editor-setup-0.1.3.exe below and run it. It installs per user (to %LOCALAPPDATA%\Programs\PDF Editor, no admin / UAC prompt), adds a Start-menu shortcut, and registers PDF Editor as an available PDF handler. Windows-only (x64).

⚠️ The installer is unsigned, so Windows SmartScreen may show "Windows protected your PC" on first run — click More info → Run anyway. (One time.)

Set as your default PDF viewer

Windows 10/11 don't let an app make itself the default PDF handler (an anti-hijacking rule), so choose it yourself: Settings → Apps → Default apps, find PDF Editor (or .pdf), and select it. The installer's final screen also has a checkbox that deep-links you there. Once set, double-clicking a PDF opens it in PDF Editor (single-instance: new tab if already open).

What's inside

Tabbed viewer (zoom, thumbnails, printing) · page manipulation (rotate / delete / reorder / insert / merge / split) · in-place text & image editing with snapshot undo/redo · highlights & review comments · Find + Extract Text with OCR fallback (bundled Tesseract) for scanned or outlined-text PDFs. Three fabricated sample PDFs ship in samples/ to try features on.
