GIF became the default format for short looping animations when the web was young and video codecs weren't practical for browsers. Today, looping video — an MP4 played silently on repeat — is almost always better in terms of file size and quality. But GIF still has specific places where it's the right choice.
Size and Quality Comparison
The gap between GIF and looping MP4 is stark:
| The same 4-second clip | GIF | Looping MP4 |
|---|---|---|
| Typical file size | 5–15 MB | 0.5–2 MB |
| Colour depth | 256 colours maximum | Millions of colours |
| Fine detail | Dithering artefacts | Sharp |
| Text in the clip | Often blocky | Clean |
| Audio | Never | Yes (but usually muted for loops) |
For the same visual content, a looping MP4 typically looks substantially better and weighs a fraction of the GIF.
When GIF Is the Right Choice
- Email: most email clients don't support video; GIF is the only practical option for animation in email bodies.
- Platforms that accept GIF but not video: some CMS comment systems, Slack, certain chat apps.
- Memes and reactions: cultural expectation in those formats; the low-fi look is often intentional.
- Very simple, flat-colour animations: a few frame logo animation where 256 colours is genuinely enough and the clip is under 2 seconds.
When Looping MP4 Is Better
- Your own website: a looping MP4 with
autoplay muted loop playsinlineloads faster and looks sharper. - Social media: platforms re-encode anyway; video handles the re-encoding better.
- Footage with skin, sky or photographic content: GIF's colour limit creates visible banding.
- Any clip over 3 seconds: GIF files grow quickly with length.
Creating Each Format
- GIF: Video to GIF — choose the clip, set dimensions and frame rate, download.
- Looping MP4 for a website: Video Compressor to get the file small, then embed with
<video autoplay muted loop playsinline>.
The Practical Takeaway
For most modern use on websites and social platforms, a looping MP4 is the better choice — lighter, sharper, more colour accurate. GIF remains the only workable option for email animation and certain platforms that specifically accept it. When in doubt, create both from the same source clip (which Video to GIF makes straightforward) and use each where it fits best.
Browser Support for Looping MP4
A looping MP4 embedded in a webpage works in all modern browsers when set up correctly:
``html <video autoplay muted loop playsinline> <source src="video.mp4" type="video/mp4"> </video> ``
The muted attribute is required for autoplay to work in Chrome and Safari. The playsinline attribute prevents iOS Safari from going fullscreen automatically. These are the four attributes every looping background or demo video on a website needs.
When Platform Matters
For content posted directly to social platforms rather than embedded on your own site, the platform usually handles looping automatically once the video file is uploaded — you don't need to add HTML attributes. The GIF vs video decision then comes down to whether the platform accepts the file type. For platform-specific video sizing and formats, see video size guide for Instagram, TikTok and YouTube.
