GIF compressor.
That 14 MB GIF is not going to send itself. Shrink it with scale, frame-rate and quality controls, or flip formats entirely: MP4 to GIF for docs and chats, GIF to video for platforms that hate GIFs. All local, all free.
Everything runs locally, files never upload
How it works
Pick a mode
Compress GIF, MP4 → GIF, or GIF → Video: three tabs, one page.
Tune the output
Compression exposes the three levers that matter: scale, max frame rate and palette quality. Video conversion adds trim, fps and width.
Convert & compare
Watch the progress bar, get before/after sizes side by side, and the file downloads automatically.
Why use this tool
The GIF format is 37 years old and it shows: 256 colors, no real compression, and file sizes that balloon past every chat and email limit. But it remains the only animation format that autoplays absolutely everywhere, so the practical skill is making GIFs small. The levers are exactly three: fewer pixels (scale), fewer frames (fps cap), and a tighter palette (quality). This tool exposes all three honestly, decodes your GIF properly: including the frame-disposal tricks optimized GIFs use, and shows you the before/after so you can stop at "good enough."
The converters cover the two directions everyone eventually needs. A product demo recorded as MP4 becomes a README-friendly GIF with the trim controls; an animated logo GIF becomes a lean MP4 for platforms and sites where video is the better citizen. Speaking of animated logos, if you exported one from our free animator and it came out heavy, this compressor is its best friend. For a logo animation engineered small from the start, that is what our custom work delivers.
Frequently asked questions
How much smaller will my GIF get?
Typical results: 40–70% smaller with scale 80% + 15 fps + Balanced quality, before any visible degradation. The before/after preview lets you judge every combination instantly.
Why is there an 8-second cap on MP4 → GIF?
Because a 30-second GIF is a crime against bandwidth. It would be tens of megabytes. Under 8 seconds is where GIFs stay shareable; for longer clips, keep them as video.
My converted video has a black background, why?
GIF transparency has no equivalent in MP4/WebM recording, so transparent areas are composited onto black. If you need transparency, stay in GIF or use the original source.
Does compression lose quality?
GIF re-encoding is lossy by nature (palette quantization), but the Sharper setting is visually lossless for most content. Scale is the gentlest lever; try it first.
Are my files uploaded to a server?
No. The decoder and encoder are JavaScript libraries running in your tab. Files never leave your machine.
