Quick answer
Sign PDF places a visible signature label on selected pages of a PDF document. It is useful for simple approvals, personal copies, and informal sign-off workflows, but it is not a certificate-based electronic signature.
Key features
- Adds a visible signature text mark to one page, a page range, or multiple locations.
- Supports common placement positions such as corners and page center.
- Runs locally in the browser with no account or upload required.
- Creates a new signed PDF and keeps the original file unchanged.
- Works for quick personal approvals and internal acknowledgment copies.
- Does not provide legally certified e-signature certificates or identity verification.
About this tool
Not every signature workflow needs a full e-signature platform. Sometimes you only need a visible name, initials, or approval mark on a PDF before sending it back by email or archiving a personal copy. Sign PDF adds that visible signature label directly onto the page area you choose, then lets you download a new file. Because signing runs in your browser, the document stays on your device during the process. This is not the same as a qualified electronic signature with identity verification, timestamp authority, or tamper-evident certificate chains. Use it for informal approvals, internal acknowledgments, and personal document copies where a visual mark is enough. For regulated contracts, notarized agreements, or enterprise compliance workflows, use a dedicated certified e-signature provider instead.
Common scenarios
Personal document copies
Mark receipts, forms, or permission slips with a signature label for your own records.
Internal acknowledgments
Place a sign-off mark on policy documents, checklists, or training confirmations.

FAQ
Is this a legally certified e-signature?
No. This browser version adds a visual signature mark only. It does not provide certificate-based e-signature compliance.
Can I place the signature on one page?
Yes. Enter a single page number or a page range to control where the signature appears.
Can I upload a handwritten signature image?
The current version uses text-based signature marks. Image signature support may be added later.
Are files uploaded to a server?
No. Signing is designed to run locally in your browser.
Will the original PDF be changed?
No. You download a new signed copy and the original file remains unchanged.
Does it work on mobile?
Yes on modern mobile browsers, though precise placement is often easier on a larger screen.
Is the signature tamper-proof?
No. A visual mark can be edited by anyone with PDF editing tools. Use certified e-signature services when tamper evidence is required.
