WebP to AVIF Converter
WebP already compresses well, but AVIF can push file sizes even lower thanks to its newer, more advanced codec. AVIF offers best-in-class compression and keeps transparency, so it is a natural next step for squeezing the most out of your images. Converting WebP to AVIF is the way to go when maximum efficiency is the goal.

Why use this converter?
This tool is built for performance-minded sites and large galleries that want the smallest possible files without visible quality loss. Transparency in your WebP carries over, since AVIF also supports an alpha channel. Everything runs locally in your browser using your device’s imaging APIs, so no software is installed and your images never leave your machine. Because AVIF encode support depends on the browser, this tool feature-detects it and offers AVIF export only when your device can encode it, with a graceful note when it cannot. Use the quality slider to tune the balance between size and detail.

Frequently asked questions
Is the WebP to AVIF converter free?
Yes, it is entirely free with no watermark and no sign-up required.
Is my file private and secure?
Completely. Your file is processed 100% inside your browser using the Web APIs built into your device. Nothing is uploaded to any server — imgic never sees, stores, or transmits your images. You can even use these tools offline once the page has loaded.
Why is AVIF export sometimes unavailable?
AVIF encoding depends on your browser. The tool feature-detects support and only offers AVIF when your device can create it, showing a friendly note otherwise.
What is an AVIF file?
AVIF (AV1 Image File Format) is a modern format based on the AV1 codec that delivers some of the best compression available while supporting transparency.
Is AVIF smaller than WebP?
In most cases AVIF produces smaller files than WebP at the same quality, though the exact savings vary by image content.
