Sign PDF

Sign documents yourself or collect signatures from others

Paper signatures are almost always a detour. Someone sends you a PDF to sign; you print it, sign with a pen, scan it back in, and email the scan. The OkFarsi Sign PDF tool (coming soon) eliminates the printer entirely. You sign directly in the browser, place the signature exactly where it belongs, and send the signed document back without ever touching paper.

Three ways to capture your signature will be supported. Draw lets you sign with a mouse, trackpad, or touchscreen in a drawing pad embedded in the tool. Type converts your typed name into a signature-style font for casual agreements where a stylized text signature is acceptable. Upload accepts a PNG of your handwritten signature (ideally scanned with a transparent background) for the cleanest, most authentic-looking output. All three produce a signature object you can reuse across documents without re-creating it every time.

Placement is the other half. Drag the signature onto the signature line, resize it, and place additional fields beside it — date, printed name, initials, checkboxes. For multi-party agreements, a planned "request signatures" flow will let you upload a document, mark signature fields for each party, and send signing links. Each signer receives their own link, adds their signature, and the tool tracks the signing status. When all parties have signed, everyone receives the completed PDF.

How the Sign PDF workflow is being designed

1. Upload the document that needs signing

   Drop the PDF into the signing workspace. The tool shows every page so you can navigate to the signature line.

2. Capture or load your signature

   Draw in the pad with a mouse, trackpad, or touchscreen; type your name for a stylized text signature; or upload a PNG of a scanned handwritten signature. Save the signature for reuse across future documents.

3. Place the signature on the document

   Drag the signature onto the signature line. Resize by dragging a corner. Add a date field, printed-name field, or initials box beside it if the document requires them.

4. For multi-party agreements, invite other signers

   Mark the signature fields for each party, enter their email addresses, and send. Each signer receives a private link, adds their signature, and the tool tracks who has signed.

5. Download the signed PDF

   Once all required signatures are in place, the tool flattens the signatures into the PDF so they survive downstream re-saves. The completed signed PDF is delivered to every party.

Planned use cases

• Sign a contract a client sent you

  Add your signature directly instead of printing, signing with pen, and scanning back in.

• Request signatures on a proposal

  Send a proposal to a prospect with a signing link so they can approve with one click instead of a back-and-forth email chain.

• Internal approval chains

  Route a document through multiple internal signers (legal, finance, CEO) in sequence, tracking status at every step.

• Personal forms and waivers

  Sign rental agreements, gym waivers, event permission slips, and any other form that asks for a signature before returning.

Privacy & security

When the tool launches, signing sessions will run on isolated workers inside our infrastructure. Documents and signature images will be removed from our servers shortly after the final download completes. For multi-party flows, each signer's access will be scoped to the document they were invited to — no signer will see other signers' emails or personal data. The signed PDF will include an audit trail (signing timestamps, signer IP addresses) for later verification. We do not currently offer qualified electronic signatures under eIDAS — what we offer is a standard electronic signature suitable for routine business and personal agreements.
