Sign a PDF

Draw your signature, add a photo of it or type your name, then drop it where it belongs. A visual signature, not a certificate-based one.

How to Sign the PDF

1
Drop your PDF in
Pick the file or drag it into the box. Your browser renders the pages and opens on the last one, because that is where most agreements are signed.
2
Draw, add a photo or type your signature
Sign on the pad with a mouse, a finger or a stylus. Or add a photo of your signature and let the white paper drop away. Or type your name.
3
Place it and download the signed file
Drag the signature onto the page, or nudge it with the arrow keys. Add the date and your initials if you need them, then save.

What this tool does

It draws your signature into the page as an image, the same way a stamp lands on paper. The picture becomes part of the page content, so it prints, survives being emailed, and looks identical in every reader. What it does not do is attach a certificate. There is no cryptographic seal binding your identity to the bytes of the file, no tamper-evident hash, and no green tick in Acrobat's signature panel. Millions of agreements are settled every day with this kind of mark: what usually matters is that both sides can see who signed. When you need more than that, the answer is a certificate-based signature from a trust service provider, not this page.

Placing it precisely, with or without a mouse

Position is stored as a fraction of the page, not as pixels, so the signature lands in the same spot whether the page is A4, Letter or a rotated scan. Drag it with a pointer, or move it with the arrow keys in one-percent steps, or five with Shift held. Two number fields take the position directly if you prefer typing. Scale runs from a quarter to double size, and one tick can copy the same signature onto every page of the document.

Where your file is processed

The PDF is opened, rendered and rewritten entirely by your own browser. It is never uploaded, never queued on a server and never stored anywhere we can reach. Your signature is no different: it lives in this tab and nowhere else. There is no account and no email step. Close the tab and both are gone from memory with it.

Frequently asked questions

Is this a legally binding digital signature?

No. This places an image of your signature on the page. There is no certificate, no cryptographic proof and no tamper detection, so Acrobat shows no signature status. Whether such a mark binds you depends on your jurisdiction and on what both parties agreed.

How is a visual signature different from a digital one?

A digital signature seals the file with a private key issued to a verified identity, so any later edit breaks the seal. A visual signature is a picture: it shows intent and identity to a human reader but proves nothing to software. Both are used daily, for different stakes.

When is a visual signature enough?

It is normal for internal approvals, delivery notes, school and rental forms, freelance contracts and most commercial agreements between parties who already trust each other. Property transfers, court filings and regulated finance usually require a qualified signature from a trust service provider instead.

Does my file go to a server?

No. Reading the pages, building the signature image and writing the signed PDF all happen inside this browser tab. Nothing is uploaded, so a contract you have not signed yet stays as private as the device it is sitting on.

Can I sign one page out of a hundred?

Yes, and that is the default: the tool opens on the last page and signs only that one. Type any page number to choose another, or switch on the option that repeats the same signature on every page when a document needs initialling throughout.

How do I remove the white background from a photo?

Upload the photo and leave the background option on. Near-white pixels become fully transparent, and pixels close to white fade out gradually rather than cutting off sharply, so the thin ends of pen strokes survive instead of looking chopped.

Is my signature kept between documents?

No. It exists only in this tab, and closing or reloading the page clears it. Nothing is written to your device or to any server. If you sign often, keep a transparent PNG of your signature on disk and upload it each time.

How do I stop the signed file from being edited?

Flatten it first, which fuses form fields and annotations into the page so they can no longer be typed into. Adding a password afterwards stops casual editing too. Neither makes the file tamper-evident; only a certificate-based signature does that.
