Make a GIF dramatically smaller without wrecking how it looks. pixelpix runs the same engines the pros use — gifsicle for fast, GIF-native optimisation and gifski for maximum quality — compiled to WebAssembly so everything happens on your own device.
Turn the lossy, colour and resize dials and watch the live size estimate; every result is saved as a version card you can compare, download or feed into another tool.
GIFs store up to 256 colours and compress each frame largely on its own, so a screen recording or a gradient-heavy clip can easily hit tens of megabytes. Compression tackles that on three fronts: reducing the colour palette (fewer colours means smaller frames), optimising how frames are stored, and optionally trimming the frame rate. pixelpix lets you turn each of these dials and shows a live size estimate, so you can trade a little quality for a lot of savings — or not.
Two engines sit behind the tool. gifsicle is fast and produces small files, ideal for most GIFs. gifski uses per-frame palettes for the best possible quality on photographic or gradient content, at the cost of a larger file. The "smaller file" and "richer colour" choices in the panel pick between them, so you are never guessing which engine suits your clip.
Like every pixelpix tool, this runs 100% in your browser: your file is never uploaded to a server, never leaves your device, and works even offline once the page has loaded.
