A free PDF toolkit for Windows that runs entirely on your own computer. Nothing is uploaded anywhere, and it works with Arabic text out of the box.
Download: PDFStudio-portable.zip (about 130 MB, no installation, no administrator rights)
- Extract the zip anywhere, for example your Desktop.
- Open the extracted folder and run
PDF Studio.exe. - If Windows shows "Windows protected your PC", click More info, then Run anyway. The app is not code-signed yet, so this warning is expected.
The SHA-256 checksum of the download is listed in the release notes of the portable release.

Arabic is shaped and ordered correctly when it is written into a PDF, and reversed or disconnected text is repaired when it is read out. The Amiri typeface is bundled.
The app runs a small server on 127.0.0.1 only. Your files stay on your
computer, and nothing is sent anywhere except the update check described below.
On start, the app asks this repository for a newer release. If one exists, a bar offers Update now. Updates are signed: the app refuses any package whose signature does not match the public key built into it. The header also has a Check for updates button. Both need an internet connection.
Requires Python 3.9 or newer.
python run.py
The first run builds its own environment, then opens http://127.0.0.1:8765.
To build the standalone application, run python build_app.py. See
docs/MAINTAINER.md for build and release notes.
