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.
