Sign a PDF in your browser
Sign a PDF free in your browser, with no upload and no account. Draw your signature with a mouse or a finger, type a name, or bring a PNG you already have. Place it on one page or on every page, then save.
A visible signature drawn onto the page, the way signing a printout is — not a cryptographic one.
In detail
A signature here is a picture drawn onto the page. You make it in one of three ways — with the pointer on a ruled pad, by typing a name in a script-like style, or by bringing a PNG of a signature you already own — and then place it by dragging it on the page or by moving three sliders. The line under the page reports, in points, the size it will print at.
Placement is stored as a share of the page a reader sees, never as absolute points, so the same mark lands on the same corner of a Letter page and of A5, and initialling a whole document is one instruction. Pages that carry a rotation are handled: a scanned page is often stored portrait and shown landscape, and the mark is mapped back through that.

- Draw with a mouse, a trackpad or a finger
- Type a name in a script-like style
- Upload a transparent PNG signature
- Drag the mark, or place it with sliders
- Initial every page in one pass
- Places correctly on pages that carry a rotation
- Pages are never re-rendered, so text stays selectable
- Who it is for
- Anyone returning a form, a lease or an agreement that needs a signature on it rather than a certificate behind it.
- Limits
- A visible signature only — not a cryptographic or PAdES digital signature, and no certificate is involved.
- Anyone with a PDF editor can take the mark off again.
- A password-protected PDF has to be unlocked before it can be signed.
- A long document is held in memory while it is written, so signing every page of one takes a moment.
- Privacy
- The PDF is read and rewritten by your own browser. Nothing is uploaded, and the signed copy is saved straight to your downloads.
How to sign a PDF in your browser
- Drop in the PDF Drag the PDF onto the drop area, or browse for it. Its first page appears, with the page count, the page size in points and the file size on the line underneath.
- Make your signature Under Make it, pick Draw and sign on the ruled pad with a mouse, a trackpad or a finger; or Type and enter a name in one of three styles; or Upload a PNG of a signature you already have. Ink color and line thickness sit beside the pad.
- Place it on the page Drag the signature on the page, or move the Width, Across and Down sliders. The line under the page reports, in points, the size the mark will print at on that page.
- Choose which pages Under Sign, keep This page, or choose Every page to initial the whole document. Every page puts the mark at the same relative spot on each one, whatever size that page is.
- Save the signed copy Name the output file and press Sign and save. The signature is embedded once as an image and drawn over the pages you chose; the pages themselves are left untouched.
Sign a PDF in your browser: common questions
Is this a legally binding digital signature?
No. This draws your signature onto the page as a picture, which is the same thing as signing a printout and scanning it back in. It is not a cryptographic or PAdES digital signature and carries no certificate, so nothing in the file proves who signed it or that the pages have not changed since. Whether a signature that looks scanned is accepted is up to whoever asked for it.
Does my PDF get uploaded anywhere?
No. The document is read, rendered and rewritten by your own browser, and the signed copy is saved straight to your downloads. Nothing about the file reaches a server, which is also why the tool keeps working after the page has loaded and the network is switched off.
Can someone remove the signature afterwards?
Yes, with a PDF editor — much as ink can be scraped off a printout. The mark is an image drawn on top of the page, not a lock on it. It records a signature; it does not protect the document.
Does signing re-compress the pages?
No. One PNG is embedded and drawn over the page, and everything already in the file is left as it is. Text stays selectable, fonts stay embedded, and every image keeps the bytes it arrived with.
Will a transparent PNG signature stay transparent?
Yes. A PNG with the background cut away around the ink keeps its alpha channel, so whatever sits under the signature still shows through. A JPEG has no transparency at all, so a signature saved as one arrives as a solid rectangle, and the tool says so when it spots one.
