Preparing file upload...
A 5MB GIF becomes a 200-500KB MP4 with better visual quality. MP4 uses modern video compression that's dramatically more efficient than GIF's per-frame approach.
GIF is limited to 256 colors per frame. MP4 supports millions of colors, producing smoother gradients and more accurate colors — especially noticeable in photographic content.
Replace heavy GIFs on your website with autoplay MP4 videos. Pages load faster, use less bandwidth, and look better. Most modern websites use <video autoplay loop muted> instead of GIF.
Twitter/X, Facebook, and many platforms automatically convert uploaded GIFs to video anyway. Uploading MP4 directly gives you more control over quality and file size.
| GIF | MP4 | |
|---|---|---|
| Colors | 256 per frame | Millions |
| File size | Large (inefficient) | 90%+ smaller |
| Audio | No | Supported |
| Autoplay | Everywhere | Most platforms |
| Transparency | 1-bit | No |
| Best for | Simple animations, reactions | Everything else |
No — GIFs don't contain audio, so the MP4 will be a silent video. You can add audio separately in a video editor.
MP4 files don't loop by default, but most platforms (Twitter, Discord) and web players can be set to loop. Use <video loop> for web embedding.
