How this works in your browser
Each frame of the GIF is decoded and fed into a video encoder, with the source frame timing carried across so the animation runs at its original speed. The pixel format is set to the widely compatible variant that phones, browsers and older players all decode, and both dimensions are rounded down to even numbers, since the codec subsamples colour at half resolution and has no way to represent an odd dimension. The index is written at the front of the file so playback can start before the download completes. The size reduction is not a matter of tuning: GIF cannot compress between frames at all, so a format that can describe a static background once instead of hundreds of times wins by a wide margin.

| Watermark on output | Never | Common on free plans |
| Usage limits | None - free, unlimited use | Often capped per day or file size |
| Works offline once loaded | Yes, for most tools | No - requires a live connection |
| Account required | No | Often, for anything beyond a trial |
Who uses GIF to Video
Sharing large GIFs
Turn an oversized animation into a file that actually sends over a message or email.
Website performance
Replace heavy GIFs with video so pages stop spending megabytes on a short loop.
Social media posting
Upload in the format most platforms convert GIFs into anyway, with better quality retained.
Archiving animations
Store a collection of GIFs in a far more space-efficient format without losing the motion.

Frequently asked questions
Why convert a GIF to video instead of keeping it as a GIF?
MP4 compresses far more efficiently than GIF for the same animated content, often producing a file many times smaller at equal or better visual quality.
Will the MP4 loop automatically?
Looping behavior depends on where you play the video; the file itself does not force looping the way some GIF viewers do by default.
Does this preserve the original animation speed?
Yes, the frame timing from the source GIF is preserved in the video output.
How much smaller will the MP4 be?
Often dramatically, sometimes by a factor of ten or more. The gap is structural rather than incidental: GIF stores every frame as a complete image, while video compression describes a scene once and then records only what changes between frames, which is exactly what an animation with a static background gives it.
What happens to a transparent background?
It becomes solid. Video has no alpha channel, so anything transparent in the GIF is filled in. For a GIF captured from a screen recording that makes no difference, but a sticker or overlay graphic with a see-through background will gain one.
Will it autoplay like a GIF does?
That depends on where you post it. Most social platforms and messaging apps autoplay short muted video exactly as they do GIFs, and several convert uploaded GIFs to video behind the scenes anyway. On your own site you would add the autoplay, muted and loop attributes yourself.
Is my GIF uploaded anywhere?
No. The conversion runs inside your browser tab.
