Which input formats are supported?

Anything your browser can decode as an image. That's usually PNG, JPG, WebP, GIF, BMP, and SVG.

Why do photos look posterized?

GIF only supports 256 colors per frame, so anything with smooth gradients or lots of colors will band. That's a limit of the format.

Image to GIF

Takes a PNG, JPG, or WebP and maps it onto a 256-color GIF palette.

What this does

This decodes any image your browser can open — PNG, JPG, WebP, and more — and quantizes it onto a 256-color palette to encode a single-frame GIF. Smooth gradients and photos band when mapped down to 256 colors, which is the GIF format's limit.

How it works

1Drop your images.
2Each one gets quantized to a 256-color palette and encoded as GIF.
3Download each result, or grab them all as a zip.
