LocalPDF

LocalPDF — Private PDF Editor. Zero Uploads. Fully Offline. Edit, merge, split, OCR, compress, sign, and convert PDFs entirely in your browser. All processing happens locally via WASM — your files never touch any server. Works fully offline after the first load. No account required. No file size limits on device. Why LocalPDF Every other PDF tool uploads your documents to a cloud server for processing. For sensitive documents — contracts, medical records, financial statements, legal filings — that's a security risk. LocalPDF is the only full-featured PDF toolkit that processes everything on your machine using WebAssembly. Your data stays where it belongs.
