Animated SVG vs Animated WebP

Both formats support animation, but they represent it completely differently — vector code versus raster frame sequences.

How Each Format Represents Animation

Animated SVG uses CSS or SMIL to programmatically animate vector shapes — infinitely scalable, tiny file sizes for simple animations, and editable after the fact. Animated WebP stores a sequence of raster frames like an animated GIF but with far better compression — ideal for photographic or complex animation that can't be represented as vector shapes.

SVG suits vector-representable motion; WebP suits photographic/complex animation

Choosing Based on Content Type

A simple animated icon or logo (a spinning loader, a morphing shape) is dramatically smaller and infinitely scalable as animated SVG — a complex animated photograph or footage-derived clip has no vector representation and must be animated WebP (or video) instead.

Photographic or footage-derived animation: animated WebP is the only real option
Content type, not just file size, should drive the format decision

Frequently Asked Questions

Is animated WebP widely supported across browsers?

Support has grown substantially in modern browsers, though always verify current caniuse data and provide a fallback (like an animated GIF or static image) for any unsupported browsers your analytics show.

Can I animate a logo as SVG instead of using an animated GIF?

Yes, and it's usually a significant improvement — a CSS-animated SVG logo is typically far smaller than an equivalent animated GIF and stays perfectly sharp at any display size or screen density.
