Overview
A PDF toolbox that keeps your documents instead of forgetting them. Quick edits run in the browser with pdf-lib; the heavy operations (OCR, compression, redaction, encryption) run on a Python service built on PyMuPDF, pikepdf, and Tesseract.
- Merge / split / reorder pages with drag and drop
- Compress, flatten, and OCR scanned documents
- Redact, encrypt, sign, and fill forms
- Saved documents with version history and full-text search
What it solves
Every "free online PDF tool" is a gamble. The lucky outcome is ads; the unlucky one is your document quietly uploaded to a server nobody can name, and the moment you close the tab, the edited file is gone.
PDFmod is account-based on purpose. Documents live in your workspace, every edit saves a new version you can roll back to, and OCR'd pages become searchable text. Simple edits never leave the browser; the rest go to a server you know the name of.
Highlights
- Python processing service: PyMuPDF, pikepdf, Tesseract OCR
- Version history on every saved document, with a per-account storage limit
- Full-text search across documents, including OCR'd scans
- Redaction, encryption, and signatures for contract-grade work
