AVIF → WebP

Does this tool upload my AVIF image to any server?

No. The entire AVIF-to-WebP conversion process runs inside your browser using Canvas and native image decoding. Your images never leave your device, ensuring complete privacy.

Why does the conversion fail on some browsers?

The conversion requires AVIF decoding support and WebP encoding support. Older or in-app browsers may not support one or both.

Does lowering the quality reduce the file size?

Yes. Lower WebP quality values create significantly smaller files, though very low settings may introduce compression artifacts.

Is WebP better than PNG or JPG for most images?

Often yes. WebP can produce much smaller images than PNG or JPG while retaining excellent clarity, making it ideal for the web.

Why is my .avif file rejected even though it has the correct extension?

Some files are mislabeled. The tool checks both MIME type and extension. If the browser cannot decode it as AVIF, conversion is blocked.

Is there a file size or resolution limit for conversion?

There is no enforced limit, but extremely large AVIF files depend on available system memory. Very large images may fail on low-RAM devices.
