GIF to MP4 Converter Free - Smaller Files
Turn an animated GIF into a video file. Drop a GIF, pick a width, and save it as MP4 (H.264) in browsers that can make it, or as WebM in browsers that cannot. A video is usually several times smaller than the same GIF, and the result screen shows the exact sizes so you can check. No watermark, no upload, no account. The conversion runs entirely in your browser.

When to use it
Shrink a heavy GIF before sharing
A long GIF can be several megabytes. Drop it in, keep the original size or pick 480 px, and compare the file sizes on the result screen.
Post an animation where video works better
Some sites and apps handle a short video better than a GIF. Choose "Repeat 3 times" if you want the loop to run a few times inside the file, because a saved video does not loop on its own in every player.
Keep the original GIF untouched
The GIF is only read, never changed. If the result is not smaller, try a smaller width and convert again.
How to use
- Drop a GIF file into the box or click to choose one. The GIF shows with its size, frame count and length.
- Pick a width and how many times the animation should repeat in the video. The note under the options tells you whether your browser will save MP4 or WebM.
- Press "Convert to video". A preview appears when it finishes. Press "Download video" to save it.
How it works
The page reads the GIF frame by frame in your browser and draws each frame on a canvas with its own display time. If your browser has a built-in H.264 video encoder (WebCodecs), the frames are encoded and packed into an MP4 file. Otherwise it records the canvas with the browser's recorder, which gives MP4 in browsers that support it (current Safari, recent Chrome and Edge) and WebM in the rest. Nothing is uploaded and no extra video codec is downloaded. GIFs have no sound, so the video has none, and transparent areas turn white. How to verify. Also available as a free REST API for developers and AI agents (edge-processed, zero retention).

FAQ
How much smaller will the video be?
It depends on the GIF. Video is often several times smaller than the same GIF, especially for long or photo-like animations, but not always. The result screen shows both file sizes so you can compare. A smaller width makes the file smaller.
Will the video look the same?
It should look very close. GIF is limited to 256 colors per frame and a video can show more, but the encoder compresses with some loss, so very sharp pixel art may look slightly softer. Transparent areas become white because video has no transparency.
Does every browser make MP4?
No. Browsers with a built-in H.264 encoder (current Chrome and Edge) and current Safari save MP4. A browser that cannot make MP4 saves WebM instead. The note under the options shows which one your browser will use before you convert, and the result screen shows the format that was saved.
Is there a watermark?
No. The video is clean with no watermark, branding or sign-up required.
Is my GIF uploaded?
No. The conversion runs entirely in your browser using JavaScript. The file never leaves your device.
Why is the video as long as the GIF?
The video uses each frame's own display time, so a 3-second GIF becomes a 3-second video. Use "Repeat" to run the loop several times in one file. Very short frame times (under 0.02 s) are treated as 0.1 s, the same way browsers play GIFs.
Are there size limits?
The page accepts GIFs up to about 4 megapixels per frame and 1,500 frames. Larger files show a message instead of converting. The MP4 path is fast; the recorder path (used when MP4 encoding is not built in) runs in real time, so a 10-second GIF takes about 10 seconds per repeat.
