How it works
- Draw your signature — or drop a photo of one on paper and let the tool remove the paper.
- Download it as PNG/SVG, or drop the PDF you need to sign.
- Click where it goes, set the width in millimetres, and download the signed copy.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see fetch the tool’s own code — and, for a few heavy tools, their open-source engine from a public CDN — plus one small page-view ping to loreatec.jp (page address and title, nothing more). None of them carry your file.
Frequently asked questions
Is this a legally binding e-signature?
It is the digital equivalent of signing on paper and scanning: fine for the everyday forms, quotes and acknowledgements that companies exchange, and just as non-cryptographic. Nothing proves who placed the image. When a contract needs certificate-based proof, use a qualified e-signature service — this tool is not one.
Why does the photo route need white paper and a dark pen?
Because the paper is removed by an automatic ink threshold (Otsu’s method): the tool finds the brightness that best separates ink from paper. Even lighting and good contrast make that separation clean; a slider lets you correct for shadows.
Which is better — drawing or the photo?
A photo of your real pen signature looks like you; a mouse signature rarely does. On a tablet or a phone with a pen, drawing is excellent. Both give a transparent PNG at print resolution.
How is it placed on the PDF?
As an image with a multiply blend, so the ink sits on the page rather than a white rectangle covering it. Text under the signature remains text — this tool does not flatten the document.
