How is a WebP image converted to AVIF?

The conversion runs on PicPerf's image processing service: your WebP is decoded and re-encoded as AVIF at high quality settings. The file is processed for the conversion only and never stored. This converter targets static images, so it's best suited to non-animated WebP files.

Is AVIF smaller than WebP?

Usually, yes. AVIF regularly produces files 20–30% smaller than WebP at a similar visual quality, with the biggest gaps on photographic content. Savings vary by image, but AVIF is currently the most efficient format with broad browser support.

Will I lose quality converting WebP to AVIF?

This tool encodes at high quality settings, so the AVIF output is visually equivalent to the source in nearly all cases. If you need absolute fidelity, a lossless encode is the safer route — but for web delivery the size savings are usually the point.

Why convert WebP to AVIF instead of serving WebP?

If your audience is on modern browsers, AVIF will deliver the same images faster. WebP's advantage is broader legacy support, so keep WebP (or a fallback) when you must support older browsers, email clients, or tools that haven't added AVIF yet.
