How it works

ConvertCabin loads a local copy of FFmpeg in this browser tab and does the work on your device — nothing is uploaded. The first use downloads the engine (~25 MB), which your browser then caches.

Because it runs locally it stays free, unlimited and private, and keeps working offline once loaded.

About compressing GIFs

GIFs store every frame as a full image, so they grow large fast. The most effective way to shrink one is to lower the frame rate or the width — both cut the data dramatically while keeping the animation recognisable.

Frequently asked questions

How do I compress a GIF?
Drop a GIF, lower the frame rate or width, and download the smaller version — all in your browser.
What shrinks a GIF the most?
Reducing the width has the biggest effect, followed by a lower frame rate. Shorter animations are smaller too.
Is my GIF uploaded?
No. It is recompressed on your device by a local copy of FFmpeg.
What is a GIF file?
GIF is a long-standing image format best known for simple animations. It's limited to 256 colors per frame, which makes it perfect for short looping clips but poor for full-color photos.
