AVIF to WebP Converter
Turn an AVIF into a WebP — still small, still transparent, but supported across every modern browser and most design tools. Free and private.
Why convert AVIF to WebP?
AVIF and WebP are both modern, compact formats — but WebP has been around longer, so more browsers, CMSs and design tools accept it. If an AVIF won’t load where you need it, converting to WebP keeps the small size and transparency while widening compatibility. Lumisphere decodes the AVIF and re-encodes WebP entirely in your browser — no upload, sign-up or watermark.

Good to know
How do I convert an AVIF to WebP?
Drop your AVIF in, choose WebP, and download — you keep the small size and transparency while gaining far broader app support.
AVIF or WebP — which is smaller?
AVIF is usually a little smaller, but WebP is supported more widely and is plenty small for most sites. Convert to WebP when you need broader compatibility without much of a size penalty.
Does WebP keep the AVIF’s transparency?
Yes — WebP supports an alpha channel, so a transparent AVIF stays transparent as a WebP.
Will every browser show my WebP?
All modern browsers display WebP, and many tools that don’t yet read AVIF do read WebP — which is exactly why this conversion is useful.
Is it free and private?
Yes — no sign-up, no watermark, no limit, and the AVIF is decoded on your device and never uploaded.
