From handwriting to a repeatable mark
Ink is thin, so the cut-off is low
A signature is a few dark strokes on a lot of paper, and the thin tapered ends sit closer to mid-grey than the body of the stroke. The default of 165 is deliberately lower than the other stamp pages: raise it and the tails of your letters go first.
What a die maker needs
To cut a physical signature stamp, a manufacturer needs solid strokes, transparent background and no grey. A greyscale scan makes someone at the factory choose the cut-off for you, without knowing which strokes matter.
Scan quality decides everything
A flatbed scan at 300 DPI on plain white paper thresholds beautifully. A phone photo carries shadow gradients that no single cut-off separates cleanly from the ink.
Blue or black
Blue is the traditional signature ink and signals an original rather than a photocopy. Black reads as more formal and reproduces better on a fax or a scan of a scan.
Never leaves your browser
The whole conversion runs on a canvas on your own machine. Your signature is not uploaded, stored or logged anywhere.

What people use it for
The jobs the editor was built around — and what it does differently on each one.
Colourways you can revisit
Every edit is a layer, not a bake. When the brand shifts, reopen the file and change the colour rather than rebuilding the variant from the original.
Cutouts with awkward edges
AI background removal that keeps hair, foliage and soft shadows instead of stamping a hard outline around them. The output is a transparent PNG, ready to place.
No export, edit, re-import loop
The Framer plugin runs on the canvas you are already working in, so a recolour or a cutout does not mean a round trip through a second application.
Ten options in the time one used to take
Recolour once and step through the alternatives, so a client review can look at the whole range instead of the one version there was time to make.
Brand colours matched exactly
Pick a colour straight off an existing asset and get the hex, rather than eyeballing it against a screenshot and hoping it is close enough.
Free to preview, priced per export
Previewing is unlimited and costs nothing. A credit is spent only when you download a full-resolution file, so exploring an idea is never the expensive part.
