How do I convert a GIF to MP4 in my browser?

Drop the GIF, choose MP4 (H.264), WebM (VP8) or Both, set Quality, then click Convert. FFmpeg.wasm encodes it on your device, and you download the video.

Why is the MP4 so much smaller than my GIF?

GIF stores each frame as a palette image, while MP4 uses H.264 video compression. The tool shows the size of each output and the percent saved against your GIF.

Does the video loop like a GIF?

No. A video plays once by default. Under Plays choose 2, 3, 5 or 10 to repeat the clip that many times and then stop; the tool does not make an endless loop.

What happens to transparent parts of my GIF?

Video has no transparency, so transparent areas are filled with your Background colour: White, Black or Custom colour. The frame is padded, not cropped, to even dimensions.

Why can I not convert a very large GIF?

The whole file is held in browser memory, so there is a size limit. It is about 2 GB on typical desktops, 1 GB on low-memory devices and 400 MB on phones, with warnings above lower sizes.

Yes. Every tool is free to use, with no account and no credit card. The work runs on your device rather than on our servers, which is what keeps it free to run.

Are my files uploaded?

No. Your files are opened and processed inside your browser and are not sent to LibraTool. Some tools first download a processing engine or AI model to your browser; that download contains no data of yours.

Does it work on mobile?

Yes. It runs in current mobile browsers on iOS and Android, with nothing to install. Very large files can be slow or run out of memory on a phone, so use a computer for those.

How It Works

GIFs are huge and play inconsistently. Converting an animated GIF to MP4 or WebM shrinks it dramatically and plays smoothly — and most platforms now prefer video. This converts it with FFmpeg in your browser.

1
FFmpeg.wasm loads once
The WebAssembly build of FFmpeg (~30 MB) downloads on first use and is cached afterwards.
2
You drop in a GIF
It's read into your browser's memory — never uploaded.
3
FFmpeg encodes a video
The frames are re-encoded to H.264 (MP4) or VP8 (WebM) with even dimensions and yuv420p for universal playback.
4
You download the video
The result — typically a fraction of the GIF's size — is offered for download and previewed with autoplay/loop.

No upload, no watermark. Convert reaction GIFs and screen captures to video privately, right on your device.
