The idea
Every "free" PDF site on the first page of Google either charges for the useful features, adds its own watermark, or quietly uploads your documents to a cloud server. We wanted something different — a toolkit where your files never leave your device, the core features are all free, and there are no dark-pattern upsells.
PaperPress does all processing inside your browser tab using JavaScript. Close the tab and everything is gone — no residue, no account, no history.

How it works
Every conversion runs inside your browser tab. The libraries are loaded once from CDN and then run locally — your files travel zero bytes over the network.
- pdf-lib — merge, split, compress, watermark, page numbers, metadata, text-to-PDF
- PDF.js (Mozilla) — rendering PDFs to canvas for preview and image export
- Tesseract.js — OCR in English, Tamil (தமிழ்) and Sinhala (සිංහල), running fully offline after the first language model download
- mammoth.js — converts .docx documents to HTML for Word-to-PDF
- JSZip — packages multi-page exports into a single ZIP download

Privacy & data
Do you store my files?
No. Your files are never sent to any server. All processing happens locally in your browser using JavaScript. When you close the tab, every file is gone.
Do you track me?
PaperPress has no analytics scripts, no cookies, and no user accounts. We do not know who you are or what files you process.
Is it really free?
Yes — completely free, no signup, no file limits, no watermarks added to your documents. There is no server to run, so there is no cost to pass on.
Can I use it offline?
Most tools work after the page loads (scripts are cached by the browser). The OCR tool downloads a language model on first use, which is then cached — after that it works offline too.
