Why animated WebP is worth a look

Animated WebP is a modern image format that behaves like a GIF but keeps full colour and compresses far better. It loops on its own and can be dropped into a web page with an ordinary image tag, with no video player needed.

Browser support is strong: current versions of Chrome, Firefox, Safari and Edge all show it. Support in other places is more mixed. Some chat apps, email clients and older software don't animate it, so check where you plan to share it. When in doubt, a GIF is the safe fallback.

Compared with MP4, WebP loops by itself, which is why it's the usual replacement for GIFs in web pages. MP4 is usually smaller still, but needs a video element to loop and play silently.

  1. 1

    Add the MP4

    Drop the file in, paste it, or import a direct link.

  2. 2

    Trim and crop

    Select the part you want and crop to the shape that suits the page.

  3. 3

    Check the WebP settings

    The format is set to WebP. Pick a width and frame rate; 480px at 15fps is a good start.

  4. 4

    Convert

    Compare the estimate with a GIF by switching format, then download.

Real uses

Where this comes in handy

A loop on a web page without a video player

Animated WebP goes in an ordinary image tag, so there is no player, controls or autoplay policy to deal with.

A lighter alternative to a GIF

When an app supports it, WebP gives you the same loop in full colour at a fraction of the weight.

Common mistakes, and what to do instead

  • Posting it somewhere that doesn't animate WebPTest where it will be seen. If it appears as a still, export a GIF for that place.
  • Using the largest quality for everythingBalanced is usually indistinguishable. Save Best for clips with fine gradients.
  • Expecting audioWebP is an image format and has no sound. Use MP4 if you need video.
Troubleshooting

Common problems and quick fixes

My app shows a still image

It probably doesn't animate WebP. Export a GIF instead.

The colours look different

Try Best quality. Colour should be close to the original; if not, tell us on the contact page.

The file isn't smaller than I expected

Busy footage compresses less. Lower the width, frame rate or length.

I need audio

WebP has no sound. Export MP4 if you want to keep a video file.
