Question 1

Why convert a GIF to MP4 at all?

Accepted Answer

Because the same animation as an MP4 is typically 80 to 95 percent smaller. GIF stores every frame almost like a photo; MP4 video compression stores the differences between frames, which is vastly more efficient. Smaller files load faster, autoplay on every social platform, loop without the GIF format's quirks, and come with real playback controls. Anywhere you would post a GIF today, an MP4 does the job better and lighter.

Question 2

Will the MP4 look as good as the GIF?

Accepted Answer

Yes, and often smoother. The converter uses the standard H.264 codec with the yuv420p pixel format every player expects, scales odd dimensions to the even sizes video requires, and adds fast-start metadata so the video begins playing before it fully downloads. Fine dithered gradients in a GIF can soften slightly, which is the honest trade of leaving a 256-colour format for real video.

Question 3

Why does the converted file sometimes have slightly different dimensions?

Accepted Answer

H.264 requires even width and height. If your GIF is, say, 333 by 251, the converter trims the scale to 332 by 250, the nearest even pair. One pixel of canvas is the entire difference, invisible in practice, and it guarantees the MP4 plays in strict players like iOS and older Android devices that reject odd-sized video.

Question 4

Can I convert a very long or large GIF?

Accepted Answer

The engine runs in your browser, so the practical limit is your device's memory: GIFs up to a few minutes and around 200 MB generally convert fine on a desktop, while phones manage less. Because nothing is uploaded, a failed attempt costs you nothing but time; for very large files, trimming the GIF first or converting on a desktop browser is the reliable route.

Question 5

Is the GIF uploaded to a server?

Accepted Answer

No. The conversion runs on FFmpeg compiled to WebAssembly inside your browser tab. Your file is read locally, converted locally and downloaded locally. That is also why the first conversion takes a moment to load the engine (about 30 MB, cached afterwards) while later ones start instantly.
