About Sign PDF
Add digital signature or draw your signature onto PDF files. PDFs are the default for anything that has to look the same everywhere, which also makes them awkward to edit once created.
Everything runs locally in your browser using standard web APIs — nothing is uploaded, queued, or stored on a server. Your files never leave your device, so there is no privacy trade-off, no file-size limit imposed by an upload, and no waiting for a round trip. It also means the tool keeps working on a slow or intermittent connection, and there is nothing to delete afterwards.
