About SafePaper
SafePaper is a private workspace of 200+ file tools — for PDFs, images and video, spreadsheets and data, developer utilities, finance, on-device image AI, audio, health data, and security — that all run inside your browser.
Why it exists
Most “free online” file tools upload your documents to a server, process them there, and ask you to trust a deletion promise. SafePaper takes the promise off the table: there is no upload endpoint for your files. The work happens on your device using WebAssembly, Web Workers, and the browser's own File and Crypto APIs, so sensitive documents — statements, scans, medical records, datasets — never leave your machine.
How the privacy model works
It is a static site: HTML, JavaScript, and CSS, with no route handler that accepts file bytes for processing. Heavy engines (PDF, FFmpeg, OCR, model weights) load on demand from the same origin or a public CDN, then run locally.
