Separating a seal from the page it sits on
It matches colour, not shapes
Every pixel close to the background colour you pick becomes transparent. The tool has no idea what a seal is, which is what makes it instant, and also why an even background matters more than a high-resolution one.
Photographs versus scans
A flatbed scan gives even lighting across the page and separates in one pass. A phone photo almost always has a brightness gradient, so a tolerance that clears the bright side leaves grey on the dark side. Shoot in flat daylight rather than under a single lamp.
Where to stop
Raise the tolerance until the paper disappears, then look at the thinnest parts of the die — usually the small text around the rim of a round seal. When those start breaking up you have gone one step too far.
Soft edges are worth keeping
Scanners blend the boundary between ink and paper across a few pixels. Those in-between pixels are what stop the result looking cut out with scissors, so a little softness at the edge is correct.
Nothing leaves your machine
A company seal is sensitive. This runs entirely on a canvas in your browser, so no copy is transmitted, stored, or logged.
How to remove a stamp background
Upload the scan
Drop in the scanned or photographed stamp. Cropping to the seal first gives the cleanest cut. Scanned to PDF instead? A single-page PDF works as well — page 1 is turned into an image in your browser.
Raise the tolerance
The background defaults to white. Increase it until the paper is gone and only ink remains.

When you need the seal alone
Digitising an office seal
Capture the company chop once and reuse it across every document you issue.
Stamping PDFs
Apply the seal directly to a file instead of printing, stamping, and rescanning.
Layering over signatures
Combine a seal with a signature where a solid background would hide one of them.
Reprinting stamped forms
Reuse one clean impression rather than stamping every copy by hand.
Or just ask
Describe the edit in your own words
Type what you want changed and the assistant does it on the canvas — each step lands as a layer you can reopen, so nothing it does is baked in.
