What forcing a signature to black fixes
Scanners wash ink out
A scanner reading dark blue or pencil often returns something closer to grey. On screen it looks acceptable; through a photocopier or a fax it can vanish. Forcing the ink to black restores the contrast the original had on paper.
Brightness is kept
Each pixel keeps its relative darkness and takes black as its hue, so a stroke that tapered still tapers. The signature reads as handwriting rather than a stencil.
What print actually needs
Office printing and photocopying are far less forgiving than a screen. Mid-greys break up into dots or disappear entirely. Black is the one value guaranteed to survive every reproduction step between you and the filing cabinet.
Transparency survives
Only visible pixels are recoloured. A transparent signature PNG stays transparent and keeps its exact outline.
Black tone or hard threshold
This tool keeps the soft edges by mapping brightness onto black. If you want every pixel forced to either pure black or nothing at all, use the Black and White Signature tool instead — that is the harder, stencil-like result.

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.
