Why sign PDFs with Moriaki?
Signatures belong on private documents — agreements, NDAs, offer letters. Uploading those to an e-signature server is exactly the risk you want to avoid. Moriaki embeds your signature locally in the browser, so the document and your signature never touch a server.
No account, no per-document fees, and no watermark. Place the signature precisely on any page, at any size, and download instantly.
Frequently asked questions
Is signing PDFs free?
Yes — free with no account, no document limits, and no watermark.
Is my document uploaded to sign it?
No. Your signature is applied entirely in your browser; the PDF never leaves your device.
Can I draw and upload a signature?
Both. Draw on the signature pad with a mouse or touchscreen, or upload an image of your signature.
Can I position the signature anywhere?

Is this a legally binding e-signature?
It places a visible signature image on the PDF, suitable for most everyday agreements. For regulated or notarised workflows, check your local e-signature laws.
