The print-sign-scan problem
The old way to sign a PDF is to print it, sign the paper, scan it back in, and hope the file size is reasonable. It needs a printer, a scanner, and several minutes. A visual electronic signature does the same thing — puts your signature on the document — in seconds, with nothing but your browser.
How to sign a PDF in your browser
1. Open the Sign PDF tool. 2. Add your PDF — it stays on your device. 3. Draw your signature with a mouse or your finger, or upload a transparent PNG of it. 4. Place it where you want — a bottom corner of the last page, or the bottom of every page — and save the signed PDF.
Visual signature vs. digital signature
What this produces is a visual signature: your signature image placed on the document, exactly like print-sign-scan. It’s perfect for everyday forms, approvals, and agreements where the other party just needs to see that you signed.
It is not a certified cryptographic digital signature — the kind that shows a verified identity and tamper-evidence in Adobe. Those require a digital certificate. For most everyday signing, a visual signature is what people actually need.
Why do it on your device
Documents you sign are often the most sensitive ones you handle — offers, NDAs, financial forms. Signing in your browser means the document is never uploaded to a signing service, so it stays private. You can also add text (like a date) before signing.
Sign your PDF privately — no printing, no upload.
