Choose a PDF, create your signature, place it, and download the signed copy. Everything runs in your browser — your document and your signature are never uploaded.
Draw with your mouse, finger or stylus. The background stays transparent.
A transparent PNG works best. JPG works too, but its white background will show.
This tool stamps a picture of your signature onto the page — like signing a printout. It is not a cryptographic digital signature or certified e-signature: it carries no certificate and nothing detects later edits. Where a certified e-signature is legally required, use a dedicated signing service.
Draw a signature with your mouse or finger — or upload a transparent PNG — and stamp it onto any page of a PDF, at the position and size you choose.

Sign PDF — Draw or Upload a Signature & Stamp It on Any Page guide
Sign a PDF in your browser: draw your signature with the mouse or your finger, or upload a transparent PNG of it, choose the page and position, and download the signed copy. It is a visual signature stamp — the honest equivalent of signing a printout.
How to use this tool
Choose your PDF with the file button or drag it onto the panel. The tool reads it locally and reports the page count.
Create your signature: draw it in the box (a mouse works, a touchscreen or stylus works better), or upload a PNG of your signature — ideally scanned or photographed on plain paper and cropped tight, with transparency if you have it.
Choose where it goes: first page, last page or a specific page number; a position preset (bottom-right is where signatures usually live); and the size, shown as a percentage of the page width.
Click Stamp signature and save the downloaded copy. Check the placement on the saved file, and re-run with a different size or position if it is not quite right — your original never changes.
A worked example
A landlord emails a tenancy agreement as a PDF. The tenant opens this tool, draws a signature on a phone screen, stamps it at the bottom-right of the last page where the signature line waits, and sends the copy back — the whole round trip takes two minutes and no printer, scanner or app install.
How it works
Your drawn signature is captured from the canvas as a transparent PNG the moment you lift the pen; an uploaded PNG is used as-is. The tool then embeds that image into the chosen page of the PDF at the preset position, scaled proportionally. Everything — the drawing, the file, the stamping — happens in your browser. No copy of your signature or document is transmitted or stored anywhere.
Frequently asked questions
Is this a legal e-signature?
It depends on the document and your jurisdiction: many everyday agreements accept a signature image, but this tool provides no certificate, audit trail or identity check, and some documents legally require a certified digital signature. If the stakes are high, ask the other party or a lawyer what they accept before relying on it.
How do I get a transparent signature image?
Sign in dark ink on plain white paper, photograph it straight-on in good light, and crop tightly. A white background will show as a white box on coloured pages; for a truly transparent PNG, trace or cut out the signature in an image editor first — or simply draw it in this tool, which produces transparency automatically.
Can I sign more than one page?
The tool stamps one signature on one page per run. To sign several pages, run the tool again on the downloaded copy for each additional page.
My drawn signature looks shaky. Any tips?
Draw big and fairly fast — slow strokes wobble. A touchscreen or stylus beats a mouse, and the Clear button costs nothing: most people get a natural signature on the second or third try. A smaller stamp size also hides minor wobble.
Is my signature or document uploaded?
Neither. Everything runs in your browser, and closing the tab wipes the signature from memory. Do not use shared computers for signatures you would not leave on a desk.
