Place a visual signature on any page

Draw a signature freehand or type one with a signature font, then drag it onto any page of your PDF. The PDF is edited locally — files are not uploaded. This is a visual approval mark, not a cryptographic digital signature (see the FAQ).

Visual signature, not cryptographic. This tool places a drawn or typed image on the page — useful for approvals, internal workflows and drafts. It does not produce a tamper-evident PAdES / PKCS#7 digital signature, which requires a certificate authority.

FAQ

About PDF signing

Is this a legally-binding digital signature?

No. This tool places a visual signature — a drawn or typed image that represents your approval, similar to signing a printed page with a pen and then scanning it. It is perfectly suitable for internal approvals, drafts, contracts that don't require cryptographic proof, and informal workflows.

A cryptographic digital signature (PAdES / PKCS#7) is a different thing: it uses a certificate issued by a certificate authority to mathematically bind your identity to the document and detect any later tampering. Producing one requires signing infrastructure that can't be done responsibly in a pure browser-only tool without a trusted certificate chain.

Do you upload my PDF?

No. The PDF is read, the signature is composited via pdf-lib, and the result is downloaded. Nothing is sent to any server.

Can I sign multiple pages?

One signature per run. To sign multiple pages, download, re-upload, pick a different page, and sign again. A multi-page flow is planned.

What if the PDF is encrypted?

Password-protected PDFs are rejected with a clear reason. Please unlock the file in a desktop tool first.

Will my signature look authentic on print?

For print and internal approvals, yes — it looks like any pen-and-paper signature scanned in. For formal legal contexts that require a cryptographic signature, you would need specialised signing software with a certificate.
