Most PDF editors upload your files to their servers — CertaDoc doesn't. It runs entirely in your browser using WebAssembly, so your documents never leave your device. Annotate, sign, stamp, and rearrange pages with zero uploads. Not a single page of your file touches our servers. Start free with 100 PDFs, no credit card required.

Built CertaDoc because I was tired of PDF tools that quietly upload your sensitive documents to their servers. Contracts, medical forms, financial statements — these shouldn't live on someone else's infrastructure. CertaDoc runs 100% in your browser via WebAssembly. Your files stay yours. Would love feedback on what features matter most to you — signatures, forms, compression? That's what's getting built next.
