A browser PDF editor with 28 tools that runs entirely on WebAssembly.
Built for anyone who has to merge, compress, sign, redact or OCR a PDF but balks at uploading a contract, an ID or a bank statement to some random online converter.
The hard problem: do real PDF work — 28 distinct operations, OCR included — entirely in the browser, offline, fast enough to actually use, with the file never leaving the device.
Every other online PDF tool sends your document to a server. For the exact documents people most need to edit — legal, financial, identity — that's the whole risk. PDFsuite compiles the PDF and OCR engines to WebAssembly so all 28 tools run on-device.
The tradeoff is engineering load and browser limits: a larger first load, and very large files are bound by the tab's memory rather than a beefy server. In exchange there's nothing to upload, it works fully offline, there are no per-file size caps, and there's no server bill — so the privacy guarantee is structural, not a policy you have to trust.
Rather than 28 disconnected features, the tools share a single engine: pdf.js for rendering, pdf-lib for document operations, and Tesseract for OCR — stitched into one consistent flow. It keeps the UX coherent and means a fix or speed-up in the core lifts every tool at once.
Same thesis as a privacy-first native app, delivered on the open web: a full PDF toolkit where the sensitive document physically never leaves your browser. Offline-capable, no size limits, one flat price.
