Frequently asked
Is it safe to sign a PDF online?
With Signet, yes — your PDF is never uploaded. All processing happens locally in your browser, so the document never touches a server.
Do I need an account to sign a PDF?
No. Signing and exporting work fully anonymously. An optional free account only adds extras like saved signatures.
Is the signature legally binding?
Signet places a visual signature on the document, which is widely accepted for everyday agreements. For qualified electronic signatures with certificates, use a dedicated e-signature provider.
Can I reuse my signature?
Yes — create a free account and save signatures to reuse across documents and devices. The PDFs themselves still never leave your browser.
