What posterising does to an image
Levels, not colours
The slider sets how many values each channel is allowed to take. At 2 levels every channel snaps to 0 or 255, giving eight possible colours. At 8 levels you get 512. That is why the count climbs so fast: the number you pick is cubed.
Built for print, not screens
Screen printing needs one physical screen per colour, so a design has to be described in a countable number of flat inks. Posterising is the digital rehearsal of that constraint, which is why the look reads as poster or T-shirt rather than photograph.
Where the bands land
Posterising quantises each channel independently and evenly. It does not pick the most common colours in your image, so a photo with a narrow tonal range can band in places you did not expect. If you want the palette chosen from the image itself, reduce the colour count instead.
Transparency is untouched
Only the colour channels are quantised. The alpha channel passes through unchanged, so a transparent logo stays transparent and keeps its exact silhouette.
Choosing a level count
Two to three levels give a stark, graphic result that suits bold subjects with clear shapes. Five to eight keep enough modelling that faces and objects still read as themselves. Above ten the effect becomes hard to see at normal viewing size.
How to posterize an image online
Upload your image
Drop in a PNG, JPG, WebP, or SVG, or click to browse. The original stays on the left for comparison.
Choose how many bands
Drag the Colour bands slider. The result redraws as you move it, so you can find the point where the image still reads clearly but the gradients have gone.

Stylised backgrounds
Turn a busy photo into calm bands of colour that text can sit on top of.

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.
