Image Format Comparison

GIF vs WebP: The Old Loop vs the Efficient Modern Alternative

GIF and animated WebP are both looping image formats, but they're from completely different eras of the web. GIF (1987) has 256-colour limitation and massive file sizes but works literally everywhere. Animated WebP (2012) has full colour, full transparency, and dramatically smaller files — but gaps in email client support mean GIF isn't gone yet.

Quick Verdict

Use GIF when…

Use GIF when you need animations that work in email clients, Slack, older messaging platforms, and contexts where animated WebP is not supported.

Use WebP when…

Frequently asked questions

Can I use animated WebP in emails?

No — most email clients (Gmail, Outlook, Apple Mail) don't support animated WebP. They either show a static first frame or nothing. For animated images in email, GIF remains the only cross-client option. Animated WebP is excellent for web pages and apps that target modern browsers.

How much smaller is animated WebP than GIF?

Typically 50–70% smaller for the same visual content and quality. A 5 MB GIF might be 1.5–2.5 MB as animated WebP. The improvement comes from WebP's superior compression algorithm (based on the VP8 video codec) which handles both spatial and some temporal redundancy better than GIF's 1987-era LZW compression.

Does Slack support WebP?

Slack supports static WebP images but animated WebP support has been inconsistent. For animated content in Slack, GIF is the reliable choice. In Discord, animated WebP is supported in modern versions of the app.
