MyPDF is a small, fast desktop app that covers the everyday PDF workflow you
would normally take to an online converter, except nothing ever leaves your
machine. No uploads, no accounts, no limits, no tracking.
Tools: merge, arrange (visual page organizer), split, pick pages, compress
with full quality control, rotate, watermark, lock and unlock, PDF to images,
images to PDF, Office to PDF, OCR with live progress, and text extraction.
Most tools accept many files at once and run them as a batch.
Requires Python 3.10+ with the pymupdf and pikepdf packages. Some features
use optional free helpers: Ghostscript (stronger compression), LibreOffice
(Office conversion) and Tesseract with ocrmypdf (OCR).
README
MyPDF
Every PDF chore, handled on your own machine. MyPDF is a small, fast desktop
app for Windows that covers the everyday PDF workflow you would normally take to
an online converter, except nothing ever leaves your laptop. No uploads, no
accounts, no limits, no tracking. Built for people who handle sensitive
documents and would rather not send them to someone else's server.
Features
🧩 Merge
Stack several PDFs into one, in any order
🗂️ Arrange
See every page as a thumbnail. Drag to reorder, rotate, or remove pages
✂️ Split
Break a PDF apart per page or by custom ranges
📑 Pick Pages
Keep only the pages you need
🗜️ Compress
Presets, full manual control, or "fit a size": tell it the MB limit and it finds settings that fit
🔄 Rotate
The whole file or selected pages
🖼️ PDF to Images
Render pages as PNG or JPG
📄 Images to PDF
Photos and scans into one tidy PDF
📝 Office to PDF
Word, Excel, PowerPoint via LibreOffice
✏️ PDF to Word
Editable .docx out of any PDF
🔒 Lock / Unlock
AES password protection, or remove it from your own files
Make scans searchable, with live per page progress
🔤 Extract Text
All the text into a .txt file
🔢 Page Numbers
Neat page numbers, covers skippable
🏷️ Metadata
Edit title, author, subject and keywords
Most tools accept many files at once and process them as a parallel batch,
with a Cancel button for long jobs. The interface speaks English and
Bahasa Indonesia. Plus the small things that make it pleasant: drag and drop
anywhere, page thumbnails with file info, live progress bars, a recent work
history, output files that never overwrite existing ones, undo and keyboard
control in the page organizer, Esc to jump back home, and a settings page for
your name, language, default OCR language and output folder.
Testing
python tests/engine_smoke.py # engine test suite, core deps only
npm run build # type check + frontend build
Both run automatically on every push via GitHub Actions.
The interface is React + TypeScript in a Tauri shell. All PDF logic lives in a
single Python engine (engine/pdf_engine.py) built on
PyMuPDF and pikepdf, which streams JSON progress lines so the UI can show real
percentages. Heavier features call battle tested externals per task:
Ghostscript for compression, LibreOffice for Office conversion, and
Tesseract + ocrmypdf for OCR.
Installing
Grab the latest setup exe from the
releases page and run it.
> Windows SmartScreen note. The installer is not code signed (signing
> certificates cost money this free project does not have), so Windows may show
> "Windows protected your PC". Click More info, then Run anyway. The
> entire source code is in this repository and every release is built from it
> in public by GitHub Actions, so you can verify exactly what you are running.
Requirements
The Windows installer ships with everything included, a bundled Python
runtime with all engine libraries, so it runs out of the box.
On Linux, macOS, or when running from source, you need Python 3.10+ with
pip install pikepdf pymupdf pillow (plus pdf2docx and ocrmypdf for those
features).
Optional, per feature (the app detects what is installed and tells you):
For OCR in languages beyond English, place the matching .traineddata from
tessdata_fast into your
tessdata folder (set TESSDATA_PREFIX if you keep it outside the Tesseract
install directory).
Development
Prerequisites: Node.js, Rust (MSVC toolchain on Windows), Python 3.10+.
npm install
npm run tauri dev # run in development
npm run tauri build # produce the installer (MSI + NSIS)
The engine also works standalone, which makes it easy to test:
Everything runs locally. The app makes no network requests: fonts are bundled,
processing is on device, and your files stay in your folders.
License
AGPL 3.0. The engine builds on PyMuPDF
(AGPL licensed), so this project shares the same license. In short: use it,
modify it, ship it, but keep the source open.
Contributing
Issues and pull requests are welcome. Adding a new tool is usually one Python
function in engine/pdf_engine.py plus one entry in the tool list in
src/App.tsx.
