How to Sign a PDF Online for Free
Published September 2, 2026 · 3 min read
Signing a PDF doesn't need a subscription service or a mailed document. This tool lets you add a signature to any page in three different ways, depending on what you have available, and places it directly into the PDF's content, not as a separate overlay.

Frequently asked questions
This produces a visual signature embedded in the PDF, similar to signing a printed page and scanning it back in — it is not a cryptographically certified digital signature (like those requiring a certificate authority). Whether that's sufficient depends on the document and jurisdiction; for contracts requiring certified e-signatures, use a dedicated e-signature service instead.
Yes — the upload option accepts a PNG or JPG image of your signature (for example, signed on paper and photographed against a plain background) and embeds it directly.
Run the tool again on the output PDF to add a second signature to a different page, or position — each pass applies one signature placement at a time.
Because your document and signature are processed entirely in your browser, neither ever passes through a third-party signing service.
