Why there's no upload step
AVIF encoding correctly in every browser needs a real encoder, not just a quick Canvas call — Chrome supports it natively but Firefox and Safari don't, so this uses a WebAssembly AVIF encoder that runs entirely on your device. Nothing is ever uploaded.
Does this keep the GIF animated?+
No — this converts only the first frame to a static AVIF image. Animated AVIF encoding needs a different, heavier pipeline; this tool is for a single still frame.
Is my file uploaded anywhere?+
No. Encoding happens entirely in your browser via a local WebAssembly module — nothing is sent to a server.
Why would I want a still frame instead of the animation?+
A sharp static thumbnail or preview image from a GIF, at a much smaller file size than the original animated file.
What if I need the animation preserved?+
Keep it as a GIF, or see the Video to GIF tool if you're starting from a video instead.
