AVIF

AVIF (AV1 Image File Format) is a modern, royalty-free image format based on the AV1 video codec. It delivers dramatically better compression than JPEG and PNG — often halving file sizes — while supporting high dynamic range (HDR), 10+ bit color, and alpha transparency. AVIF is supported by Chrome, Firefox, and Android.

Frequently Asked Questions

Is converting AVIF to WEBP free?

Yes. This AVIF → WEBP converter runs entirely in your browser and is completely free — no account, no credits, no watermark.

Which devices and platforms can I use to convert AVIF to WEBP?

Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.

Are my AVIF files uploaded to a server?

No. Files never leave your device. The entire AVIF → WEBP conversion runs locally in your browser, so your data stays private.

Can I convert multiple AVIF files at once?

Yes — batch conversion is supported. Add as many AVIF files as you like and convert them to WEBP in one pass, then download the results together.

What is the maximum file size?

There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.

Will converting AVIF to WEBP reduce the quality?

Because both formats use lossy compression, the WEBP output will not bring back any quality that has already been lost in your AVIF file. Avoid repeated re-encoding to keep the best quality.

Will transparency be preserved when converting AVIF to WEBP?

Yes. Both AVIF and WEBP support alpha-channel transparency, so transparent areas of your file are kept unchanged in the WEBP output.

How will the file size change after converting AVIF to WEBP?

Both formats use comparable compression, so the WEBP output will be similar in size to your AVIF file — typically within 10–20% of each other.
