How it works

Three steps. No upload, no signup.

  1. 1

    Drop your file

    Click the dropzone above or drag a MP4 from your desktop. Files of any size, there's no upload, so there's no upload limit.

  2. 2

    Convert in your browser

    The conversion runs entirely in this tab using JavaScript and WebAssembly. Your file never touches our servers, we don't have any.

  3. 3

    Download

    Get your GIF the moment the conversion finishes. Convert another, or close the tab.

Files stay on your device

Your file is never uploaded. The entire conversion runs in your browser using WebAssembly. We can't see what you convert because we have no server to see it.

No file size limit

Server converters cap free users at 1-2 GB and gate larger files behind a paid plan. Since nothing uploads, our limit is whatever your browser can handle.

Free, no signup, no ads on conversions

No account required. No watermark on the output. No queue. Drop a file, get a converted file.

Why convert MP4 → GIF

What this conversion is actually for

GIF autoplays silently and loops everywhere, Slack, Discord, GitHub READMEs, docs, places that don't allow video embeds. Converting a short MP4 clip to GIF makes it shareable in all those text-first contexts.

A real example

You recorded a 4-second screen capture of a UI bug as MP4. The bug tracker doesn't embed video but does render GIFs inline. Convert here, paste the GIF into the ticket, reviewers see the repro without downloading anything.

Troubleshooting

The GIF file is huge / bigger than the MP4.

GIF is an ancient, inefficient format, a 5-second clip can easily exceed the source MP4. Keep clips short (under ~6s), and crop to the region that matters. If the destination accepts video, MP4 is dramatically smaller; GIF is only for places that won't take video.

Colors look banded / washed out.

GIF is capped at 256 colors per frame, so gradients and video footage band visibly. This is a hard format limitation, not a conversion bug. Screen recordings with flat UI colors convert cleanly; camera footage will always posterize.

Formats involved

About MP4 and GIF

MP4, MPEG-4 Part 14

MP4 is the dominant video container on the web, H.264 video plus AAC audio, in a structure designed for streaming. Every browser, mobile device, smart TV, and editing tool reads MP4. The format is technically a container (not a codec), so two MP4 files can have very different internal codecs, but the H.264+AAC default is what enables universal playback.

How to open

Every video player on the planet, VLC, QuickTime, Windows Media Player, browsers (HTML5 video), iOS, Android, smart TVs, game consoles. Universal.

GIF, Graphics Interchange Format

GIF dates to 1987 and is best known today for animated short clips. The format is limited to 256 colors per frame, which is why photographic GIFs look blotchy, but for low-color animations and reaction loops it's the universal compatibility format. For any animation longer than a few seconds, MP4 is dramatically smaller (often 10-20×) and every social platform converts uploaded GIFs to MP4 internally.

How to open

Every browser and OS displays GIFs inline. Windows, macOS, iOS, Android, and Linux all open them by default with no extra software.

FAQ

Common questions

Is this MP4 → GIF converter really free?

Yes. No signup, no watermark, no daily file count limit. Every conversion runs in your browser, your file never touches our servers because there are no servers.

Where does my file go when I convert it?

Nowhere. The conversion runs entirely in your browser using JavaScript and WebAssembly. Your file is never uploaded to our servers. We don't have any servers handling files, there's nothing for us to log, store, or accidentally leak.

What's the maximum file size?

Whatever your browser can hold in memory. Practically, this means a few hundred MB on most computers, significantly larger than the 1-2 GB caps that server-upload converters charge for. Very large files (multi-GB) may require closing other browser tabs first.

Why convert MP4 to GIF?

Web video, mobile video recording, video sharing. Short animated loops; reaction images; legacy compatibility. The most common reason to convert is compatibility, GIF works in places where MP4 doesn't, or vice versa.

How do I open a MP4 file in the first place?

Every video player on the planet, VLC, QuickTime, Windows Media Player, browsers (HTML5 video), iOS, Android, smart TVs, game consoles. Universal.

Does this work offline?

Once the page is loaded, the conversion itself runs entirely offline. The first time you use a tool, your browser downloads the conversion library (a one-time cache). If you reload while offline, the page won't load, but you can install the site as a Progressive Web App for full offline use.

Can I convert multiple files at once?

Single file at a time for now. Batch conversion is on the roadmap, for now, drop one file, download the result, then convert the next.
