PNG to GIF
Quantise a PNG down to a 256-colour GIF palette. A photograph loses its gradients; flat graphics and line art come through almost untouched.
Runs on your device. The file is never uploaded.
PNG to GIF clusters every colour in the source down to 256 at most, then snaps each pixel to the nearest survivor with no error diffusion. Photographs band. Flat artwork and line art often have fewer than 256 colours to start with and come through untouched. Clear pixels are written opaque, since no transparent index is set.
Questions
Does PNG to GIF upload my files?
No. PNG to GIF runs inside this browser tab, in a Web Worker on your own machine, and no part of your file is sent anywhere. There is no upload step to skip — the tool cannot reach a server even if it wanted to, and the counter on the homepage shows the number of outbound requests the page has made: zero.
How many files can I use at once?
Drop as many as you like. Each file is handled separately and comes back as its own result, so twenty files in means twenty results out.
What can I change about the result?
Nothing to configure — it does one thing, and the result is the same every time you run it on the same input.
Is PNG to GIF free, and do I need an account?
It is free and there is no account, no sign-in and no quota. Nothing is metered because nothing runs on a server — the only limit is your own device's memory, which is what decides how large a file it can handle.
Does it work offline?
Yes. The whole site is stored in your browser after the first visit, so PNG to GIF keeps working with the network off. Tools that use a machine-learning model download that model once, on first use, and run offline afterwards.
Can I use PNG to GIF outside the browser?
Yes. Every tool here is the same code on three surfaces: this page, a CLI command, and an MCP tool an AI agent can call. `png-to-gif` is the name it goes by on all three.
