ELAI · Free, browser-only, no account
Drop an ELAI-signed PDF below. We check the cryptographic signature against the issuer's key — and tell you, in plain language, whether it's authentic.
Verification runs entirely on your device. The PDF is never uploaded.
Anyone can verify any ELAI-signed document. Forever, free.
If a single byte of the PDF changed after signing, the signature breaks. We tell you.
