GIF is a wonderful format with terrible compression — it predates every modern video codec, stores full frames with a 256-color palette, and routinely turns three seconds of animation into a 15 MB download. Re-encoded as MP4, the same clip typically shrinks by 90% or more and plays smoothly everywhere video plays.
This is why social platforms convert GIFs to video the moment you upload them. Doing it yourself first means you control the result — and here the conversion happens in your browser, so the file never uploads anywhere until you decide where it goes.

Frequently asked questions
How much smaller does the MP4 get?
Dramatic reductions are normal — 80–95% for typical animation GIFs, because modern video compression only stores what changes between frames instead of repeating them. Short clips with lots of motion benefit most.
Will the MP4 still loop like the GIF did?
The video contains one pass of the animation; looping is the player's choice. Most chat apps, social feeds, and web players loop short MP4s automatically, so in practice the behavior matches the GIF.
Does the MP4 have sound?
No — GIFs contain no audio, so the video is silent. If a platform shows a mute icon on it, that is just how it labels soundless video.
Is my file uploaded to a server?
No. ConvertUno runs entirely in your browser on your own device. Your file never leaves your computer or phone — there is no upload at all.
Is it really free, with no watermark?
Yes. Processing happens on your device, so serving you costs us almost nothing — no watermark, no account, no file-size limit, no daily quota.
