AttestOnce — document approval without an account

Upload a PDF, share the link, and collect approval decisions. Recipients open the link, enter their name, and approve or reject — no signup, no password, no app to install. AttestOnce records approval decisions; it is not a legally binding electronic signature service.

PDF files only, up to 25 MB on the free plan. Export other formats to PDF before uploading. Each decision is time-stamped and linked to the document by cryptographic hash.

AttestOnce needs JavaScript. Please enable it to upload a PDF, review a document, or record a decision.
