A small Windows desktop app that converts PDF files to TIFF. Batch conversion, multi-page TIFF output, and an English / Turkish interface (English by default).
Free for personal use. Use it at home, for study, hobby projects and other noncommercial work at no cost — no fee, no registration, no telemetry. Commercial use is not permitted; see License below.
Rendered with pypdfium2 (PDFium),
written with Pillow, GUI in Tkinter, packaged into a
single .exe with PyInstaller.
- English / Turkish interface — language selector in the top right, English by default
- Select multiple PDFs at once, one output per PDF
- Resolutions: 200 / 300 / 400 / 600 DPI
- Color modes: black & white (1-bit, threshold 180), grayscale, color
- Compression: CCITT Group 4 (black & white only), LZW, Deflate
- Output as one multi-page TIFF per PDF, or one TIFF per page in a subfolder
- Asks before overwriting existing output: Overwrite / Overwrite All / Skip
- CONVERT turns into CANCEL while a job is running
- Output folder write access is verified before the job starts
- Errors are reported per file in the selected language; good files still convert
- No installer, no configuration file, no network access at runtime

A running conversion — the main button becomes CANCEL, the file buttons are locked and the status line shows the current page:
A ready-made PDFtoTIFF.exe is attached to the
latest release — one
self-contained file, Windows 10/11 64-bit, SHA-256
b476c149663981c574bde26b2d675afeb759f259a6c09f378056f690dfaa8dee. Otherwise build
it yourself with the steps below.
The executable is not code signed, so SmartScreen may show Windows protected your
PC on the first run — choose More info → Run anyway. Launch also takes a
couple of seconds while the bundled archive unpacks to %TEMP%\_MEI*.
Requirements: Python 3.11 or 3.12 with Add Python to PATH enabled.
- Double-click
EXE_Olustur.bat. - The first run needs an internet connection — the packages in
requirements.txtare installed into.venv. - The build produces
dist\PDFtoTIFF.exe.
Run from source instead:
python -m venv .venv
.venv\Scripts\activate
pip install -r requirements.txt
python PDFtoTIFF.py- CCITT Group 4 only applies to 1-bit black-and-white TIFF. For grayscale or color output the option is not listed; LZW is used instead.
- Pages are rendered by PDFium at the requested DPI (scale = DPI / 72), so output size and quality follow the source pages.
- Files that cannot be read (password protected, corrupt, not a PDF) are listed in the result dialog with a reason, and the remaining files are still converted.
- Very large pages at high DPI need a lot of memory; Pillow's decompression bomb guard is disabled on purpose so big-format scans can be converted.
Contributions are welcome — bug reports, fixes, translations and small features. See CONTRIBUTING.md for the development setup, the checklist to run before opening a pull request, and how the licence works for contributions.
Coding agents should read AGENTS.md first: it documents the layout and the invariants that keep the two-language UI and the threaded worker correct.
