Sign PDF

Sign PDF Online Free

Use Sign PDF when everyday paperwork needs a visible signature: approval forms, school documents, delivery confirmations, simple agreements, invoices, or internal sign-offs.

Draw a signature, type one, or use a signature image, then place it on the page and download a signed copy while keeping the original file unchanged.

Place the signature on a PDF page

Supported formats

Input: PDF files supported by the browser PDF workflow.

Approval forms and acknowledgements
School or office paperwork
Delivery confirmations and simple agreements
Internal sign-offs where a visible signature is enough

Limits to know

This tool adds a visible signature layer and does not cryptographically prove identity.
Some organizations require a certificate-backed signing workflow instead.
Damaged, protected, or unusual PDFs may need a different workflow first.

How it works

Add the PDF that needs a signature.
Draw, type, or upload the signature, then place and resize it on the page.
