Does WebP to AVIF keep transparency?

Yes when the source WebP includes an alpha channel. We encode with alpha retained for overlays and UI assets.

Will every WebP get smaller as AVIF?

Usually for photos; not always for tiny graphics. Always A/B the byte size before replacing production assets.

This tool targets still images. Animated WebP is not a supported workflow here—export a still frame or use video tooling.

Can I go back to WebP later?

Yes—use our AVIF to WebP page if a partner still requires WebP after you experiment with AVIF.

About WebP to AVIF conversion

WebP is widely supported for web photos and graphics. AVIF often compresses further at similar quality. Encode WebP to AVIF when your pipeline is ready for AVIF and you want smaller files—with alpha kept when the WebP is transparent.

Why encode WebP to AVIF

Frequently smaller than WebP at comparable visual quality
Transparent WebP can become transparent AVIF
Forward-compatible delivery for AVIF-capable browsers and CDNs
Useful when upgrading an existing WebP asset library

When to convert WebP to AVIF

Migrating a WebP image set to AVIF-first delivery
Your CMS or static host now accepts AVIF uploads
RUM shows AVIF support and you want fewer bytes
WebP logos or UI with alpha should stay transparent

Many teams already standardized on WebP. AVIF is the next step when analytics and CDNs show broad decode support.

This page re-encodes WebP to AVIF in the browser. Transparent WebP keeps alpha; opaque WebP stays opaque. Quality is adjustable like JPEG.

Typical WebP to AVIF workflows

Bulk-upgrade marketing WebP heroes, convert CMS exports before an AVIF rollout, or experiment with size savings on a subset of pages. Compare AVIF vs original WebP at the same visual quality setting.

WebP vs AVIF

Keep WebP when tooling, ad specs, or older WebViews block AVIF. Prefer AVIF when you control the stack and want maximum compression.

Neither replaces PNG for endless lossless editing. For final web delivery, AVIF is often the smaller of the two modern formats.
