Frequently asked questions
How do I make a transparent signature?
Sign with a dark pen on plain white paper, photograph it in good light and upload the picture. The tool removes the paper, crops around the ink and lets you save a PNG with a transparent background, which you can place on any document.
How do I get the best result?
Use a black or dark blue pen, a thick-enough line, and even light with no shadows across the paper. Hold the camera straight above the page. If paper marks remain after cleaning, raise the background slider; if thin strokes vanish, lower it.
My form wants the signature as a JPG under 20 KB. How?
Choose JPG, set the width the form asks for, tick “Keep the file under a size limit” and enter the maximum. The tool lowers the quality just enough to fit while keeping your size.
Can I use the result to sign a PDF?
Yes. Save the transparent PNG here, or skip this step: the Sign PDF tool in the PDF Toolkit can make a signature itself and place it on a page in one go.
Is my photo uploaded to a server?
No. The cleaning is done in your browser, so the photo never leaves your device.
