About this tool
Animated GIF is a 1989 format doing a job H.264 does far better: the MP4 version of a GIF is typically 5–10× smaller and plays smoothly instead of stuttering. That's why platforms like X and WhatsApp silently convert uploaded GIFs to video — this tool just lets you do it up front, locally in your browser.
Because GIFs carry no sound, the output is a silent H.264 MP4 with no audio track at all, which also keeps the file as small as possible. One thing that doesn't carry over is looping: MP4 has no loop flag, so repetition is the player's job — add the loop attribute to an HTML <video> element or enable repeat in your player; most chat apps loop short videos automatically anyway.
Conversion runs in a Web Worker in your browser — GIFs are never uploaded.
Frequently asked questions
Why convert a GIF to MP4?
Size and smoothness. H.264 compresses animation far better than GIF's 256-color, frame-by-frame format, so the MP4 is typically 5–10× smaller and plays without the stutter large GIFs cause. It's the same trick platforms like X and WhatsApp apply automatically — you're just doing it up front.
Will the MP4 have sound?
No — GIFs contain no audio, so the output is a silent H.264 MP4 with no audio track at all. That also keeps the file as small as possible; you can add music later in any video editor if you need it.
Does the loop carry over to the MP4?
Not inside the file — MP4 has no loop flag the way GIF does. Looping is handled by the player: use the loop attribute on an HTML <video> element, or enable repeat in your player. Most chat apps loop short videos automatically.
Is quality lost in the conversion?
Practically none. The source GIF is already limited to 256 colors per frame, and H.264 at a high-quality setting preserves that detail comfortably — the MP4 usually looks identical while being several times smaller. Conversion runs locally in your browser; the GIF is never uploaded.
