Sign PDF
Sign PDF online by drawing, typing, or uploading a signature. Place signatures on contracts, forms, and approval documents without printing or scanning.
What this tool is best for
Use Sign PDF when the document is ready for approval, but still needs one or more visible signatures before it can be sent back, filed, or archived.
Why people use it
- Matches high-intent signature queries with a narrow workflow users can finish in minutes.
- Supports the common “review, sign, return” pattern for contracts, consent forms, and internal approvals.
- Removes the print-sign-scan loop that still slows down many document teams.
What to watch for
- This page is best for visible electronic signatures, not certificate-based digital-signature compliance workflows.
- If the file also needs markup, stamps, or comments, users may need to continue in <a href="/en/tools/edit-pdf">Edit PDF</a> after signing.
- If the signed file needs access control, add a password with <a href="/en/tools/encrypt-pdf">Password Protect PDF</a> after signing.
Supported inputs
single PDF, contracts and forms, typed, drawn, or uploaded signatures
Common outputs
signed PDF, approval-ready document, shareable final copy
About This Tool
Sign PDF is designed for the last mile of document completion: the file is already prepared, but it cannot move forward until someone signs it. That shows up in contracts, HR forms, client approvals, vendor documents, school paperwork, and other workflows where printing and rescanning is pure friction.
The landing page should answer a narrow intent clearly: can I add a visible signature quickly, place it exactly where it belongs, and return the document without switching to desktop software? That is different from a broad editor. Users here want a fast signing action, not a generic markup workspace.
This tool works best when the PDF is already final and only needs signatures. If the document still needs highlights, comments, or text changes, users should start in Edit PDF. If the final signed copy needs to become non-editable before sending, Flatten PDF is the cleaner next step. If the signed document also needs restricted access, continue with Password Protect PDF.
For SEO, that distinction matters. “Sign PDF online” is a completion query, and the page should stay focused on signature placement, multi-signer practicality, and a fast return-to-sender workflow.

Frequently Asked Questions
Is an electronic signature legally binding?
Electronic signatures are legally recognized in many places, but some documents require a specific certificate-based digital signature or local compliance process.
Can I sign documents online without printing?
Yes, upload the PDF, create or upload your signature, place it on the page, and download the signed copy.
Is this the same as a digital signature?
No. This tool adds a visible electronic signature. For certificate-style validation workflows, use a dedicated digital signature tool when required.
Can I save my signature for future use?
Yes, saved signatures stay in your browser so you can reuse them quickly on future documents.
Can I add multiple signatures to one document?
Yes, you can add as many signatures as needed, positioning each one independently on any page.
How do I make the signed PDF harder to edit?
After signing, use Flatten PDF to make visible elements part of the page, then use Password Protect PDF if the file also needs access control.
