Converting AVIF to WebP falls back to a format with broader tooling support and faster encoding while retaining most compression benefits. WebP is supported in every current browser and most image editors; AVIF is newer and some tools still lag.

Lossy-to-lossy transcoding adds some quality loss. At matched quality settings WebP files are typically 20–30% larger than AVIF. WebP tops out at 8-bit color, so HDR AVIF content is tonemapped during conversion.
WebP runs in every major browser, modern OS, and most image editors. It's effectively a universal modern format for web delivery.
AVIF is an image format built on the AV1 video codec, standardized in 2019. It supports HDR, wide color gamut, 12-bit depth, alpha, and animation. At matched perceived quality it's typically 50% the size of JPG and 20% smaller than WebP. Support is near-universal in modern browsers but spottier in image editors.
WebP is Google's 2010 image format based on the VP8 video codec. It offers lossy and lossless modes, full alpha transparency, and animation in a single container. At matched quality it's typically 25–35% smaller than JPG or PNG. Every major browser has supported it since 2020.
Slightly, in compression efficiency. WebP files are typically 20–30% larger at equivalent quality. In exchange you get faster encoding, broader tool support, and less tonemapping risk for HDR content.
Yes. WebP supports full alpha channels in both lossless and lossy modes. Transparency transfers cleanly.

Yes. The converter runs entirely in your browser using WebAssembly. Your images are never uploaded, never sent to a server, and never leave your device.
There's no hard limit, but because everything runs in your browser you're bounded by available memory. Very large images (over a few hundred megapixels) can hit browser memory limits. Process in smaller batches if you run into issues.
