MP4 files are typically up to 80% smaller than the same GIF while looking better — MP4 supports millions of colors versus a GIF's 256, and uses far more efficient compression. Smaller MP4s load faster, use less mobile data and battery, and improve Core Web Vitals, which is why most sites and social platforms prefer MP4 over GIF.

Yes. Every frame, the timing, and the loop are preserved. The MP4 plays exactly like your original GIF, just smaller and sharper. Most players and embeds autoplay and loop muted MP4s by default.

No. Conversion runs entirely in your browser using WebAssembly (ffmpeg.wasm). Your file never leaves your device — it is not uploaded, stored, or transmitted, and it is cleared from memory when you close the tab.

The converter uses H.264 with a yuv420p pixel format for maximum compatibility across browsers, phones, and editors. You get smooth gradients and clean motion at a fraction of the GIF's size. For very long or high-resolution GIFs, processing happens locally so speed depends on your device.

Yes. MP4 is the preferred format almost everywhere — embed it with a <video> tag for autoplay/loop on websites, or upload directly to X, Discord, Slack and most social platforms, which display MP4 more reliably (and with higher size limits) than GIF.
