A photo of your signature on white paper works. PNG with a transparent background looks best.

How it works
- Drop the PDF onto the bench, or pick it from your device. The first page appears below.
- Draw your signature, type your name, or upload a picture of it. Then drag it to the right spot and resize it.
- Press Add signature and download the signed copy.
This tool puts a picture of your signature onto a page of a PDF. That is the whole of what it does, and it is worth being plain about it, because the word signature carries more weight than the operation deserves. The result is a PDF with an image on it — the same thing you would get by printing the page, signing it with a pen, and scanning it back in, minus the printer.
Whether that is enough depends entirely on who is asking for the document. For a great many everyday forms — a rental application, a permission slip, a consent form for the dentist, an internal approval — an image of a signature is exactly what the other side expects and all they will look at. For anything where the recipient needs cryptographic proof of who signed and that nothing changed afterwards, they will ask for a certificate-based digital signature from a dedicated service, and this tool is not that. If you are unsure which your situation is, ask the person who sent the form.
Three ways to make the signature are offered. Drawing with a mouse rarely looks good; drawing with a finger on a phone or a pen on a tablet looks much better. Typing your name produces neat handwriting-style text, which some recipients accept and some do not. Uploading works well if you sign a piece of white paper, photograph it, and use that — a PNG with a transparent background looks cleanest, but a plain photo on white is fine.
The signature is stamped onto the page content itself, so it prints and displays everywhere. Your original file is untouched; the signed copy is a new file.
Questions people ask
- Is this the same as a digital signature?
- No. This places an image of your signature on the page, like signing on paper and scanning it. A certificate-based digital signature involves cryptographic keys and identity checks, and needs a dedicated service. Which one you need depends on who is receiving the document.
- Will the recipient accept a signature made this way?
- For most everyday forms, yes — it is what people expect when they ask you to sign and return a PDF. For contracts or filings that require verified identity, they will usually say so and point you to a specific signing service. When in doubt, ask them.
- Which way of making the signature looks best?
- Uploading a photo of your real signature on white paper, or drawing with a finger or stylus on a touchscreen. Drawing with a mouse tends to look shaky. Typing is quick and tidy but is clearly a font, not a hand.
- Can I sign more than one page?
- One placement per run. Sign the first page, download the result, then load that file again and sign the next page. Each pass adds one signature.
- Can the signature be removed by someone later?
- It is drawn into the page content, so a viewer cannot simply delete it, but a PDF editor could. Nothing here locks or protects the document — that is a separate step if you need it.
- Does my document or my signature get uploaded?
- No. The page preview, the signature drawing and the stamping all happen in your browser on this page. Neither the PDF nor the signature image leaves your device.
