FreeSign provides a free in-browser electronic signature service that never uploads PDFs. It hashes documents locally, captures signer intent with OTP, issues per‑user certificates, and adds OpenTimestamps proof, delivering a standard PAdES‑B‑T signed PDF verifiable in Adobe Reader, OpenSSL and pyHanko. The platform supports 29 languages, requires no account, and runs entirely in the browser, targeting EU eIDAS AES and US ESIGN/UETA compliance.
