How to sign a PDF in 4 steps
Add the PDF
Drag the file onto the upload area or click to pick it. It's read only in your device's memory.
Create the signature
Draw the signature in the box with your mouse or finger, or upload a PNG image with a transparent background.
Position it on the page
Drag the signature to the right place and use the corner to adjust the size. On multi-page PDFs, choose the page.
Download the signed PDF
Click process and download. No copy is kept anywhere.
Sign without printing or scanning
The old way to sign a digital document is tedious: print, sign by hand, scan and send it back. Besides being slow, it loses quality and wastes paper.
Here you add the signature straight onto the PDF: draw on screen or use an image of your signature, position it wherever you want and download the finished file. Fast and without leaving the browser.
Draw or upload an image
You can draw the signature on the spot, with the mouse on a computer or your finger on a phone — ideal for a quick signature. Or you can upload a PNG image of your signature (with a transparent background, so it sits well over the document).
Once created, the signature becomes an element you position freely: drag to move and use the corner to resize, keeping the proportion so it doesn't distort.
It is a visual signature, not a digital certificate
The tool stamps the image of your signature over the page, as if you had signed with a pen and scanned it. It covers the most common use — proposals, authorisations, internal forms — and saves you printing, signing and scanning.
What it is not: a certificate-based signature, which uses cryptography to prove authorship and detect later alteration. If the document requires full legal validity, a digital certification platform is the route.
How to position it well
You pick the page, drag the signature into place and adjust the size by the corner. The position is stored as a fraction of the page, not in pixels, so the result stays consistent across sheets of different sizes.
Use a PNG with a transparent background so the signature does not sit inside a white rectangle. If you draw on screen, transparency comes ready.
The signature and the PDF stay on your device
Both the document and your signature drawing are processed in the browser. Nothing is uploaded.

Frequently asked questions
Can I draw the signature?
Yes. You draw in the box with your mouse or finger, or you can upload a PNG image of your signature.
Can I choose the page?
Yes. On multi-page PDFs, you select which page to place the signature on.
Does the signature get distorted?
No. When resizing, the proportion is kept so the signature doesn't stretch.
Does this signature have legal validity?
It's a visual signature (the image over the page). It's not a certificate-based digital signature. For reinforced legal validity, use a qualified signature service.
