Animated GIFs are huge for what they show, and many platforms won't accept them as video. Convert a GIF to an MP4 or WebM that is usually a fraction of the size, with the same frames and timing, without uploading it anywhere.

Overview
GIF stores each frame as a 256-color image compressed with LZW, a method from the 1980s. Video codecs such as H.264 compress across frames, storing only what changes, so the same animation as an MP4 is commonly 5–20 times smaller. That's why sites like Twitter/X and Imgur quietly convert uploaded GIFs to video. This converter does the same on your own device, and tells you exactly how much smaller the result is.
You can output MP4 with H.264, which plays on phones, social networks, slides and web pages, or WebM with VP8, an open web format that works well as a second source next to an MP4. Because H.264 needs even dimensions, odd-sized GIFs are padded by a single pixel rather than stretched. The output has no audio track, since GIFs never have sound.
Unlike GIFs, videos usually don't loop by themselves when posted, so a very short animation can feel abrupt. The Repeat setting writes the animation into the video 1 to 10 times, and the tool shows the resulting length. Speed can be adjusted from 0.5× to 2×, keeping the GIF's own frame timing otherwise intact.
MP4 and VP8 have no transparency. If the GIF has see-through areas, the tool detects it and lets you fill them with a solid color (white, black, light gray or any custom color), so transparent edges don't turn into random colors. Conversion runs in FFmpeg compiled to WebAssembly, a one-time download of about 31 MB that is cached afterwards; typical GIFs convert in a few seconds.
| GIF | MP4 (H.264) | WebM (VP8) | |
|---|---|---|---|
| Colors | 256 per frame | Millions | Millions |
| Typical size | Large | 5–20× smaller | Similar to MP4 |
| Transparency | 1-bit | No | No (in this tool) |
| Autoplay in email | Yes | Rarely | Rarely |
| Best for | Email, legacy places | Web, social, apps | Open web pages |
Drop an animated GIF into the converter to see its size, dimensions, frame count and duration.
Choose MP4 (H.264) or WebM (VP8).
Set how many times the animation repeats and, if you like, change the speed.
If the GIF has transparency, pick a fill color.
Click Convert, compare the sizes and download the video.
Use cases
Replacing a 6 MB hero GIF with an autoplaying, muted MP4 of a few hundred kilobytes is one of the easiest page-speed wins, and the animation looks the same.
Apps that only accept video won't take a GIF. Convert it to MP4 and repeat it a few times so the clip is long enough to watch comfortably.
Video editors and some presentation tools handle MP4 better than GIF. Converting first gives you a clip you can trim, layer and export like any other footage.
A large reaction GIF may exceed a chat app's limit. As an MP4 it is usually small enough to send directly.
Pro tips
Answers to common questions about the gif to mp4.
It depends on the content, but 5–20× smaller is common for photographic GIFs. Very small or flat-color GIFs gain less, and the tool tells you when the video isn't smaller.
Video files don't carry a loop flag. Players and websites loop them when told to (for example with the HTML loop attribute). The Repeat option writes several loops into the file for places where you can't control playback.
MP4 and VP8 can't store transparency, so transparent pixels are filled with the color you pick. White is the default; the option appears only when the GIF actually contains transparency.
The video is encoded at a high quality setting, so it looks essentially the same as the GIF. Since the GIF already had only 256 colors per frame, there's no detail to lose that wasn't already gone.
No. ToolEnhancer processes files on your own device inside the browser. They are never sent to, stored on or seen by our servers.
