How to convert AVIF to WebP

Choose an AVIF, adjust the WebP settings, and download the result without uploading your image.

Select an image from your device or drag it into the upload area.

Choose quality, dimensions, and an optional maximum file size.

Review the preview and file size, then save the converted image.

This free online AVIF to WebP converter includes the following controls and output tools:

Private browser conversion. The image is processed locally and is not uploaded.
Custom dimensions. Set an exact width and height, lock the aspect ratio, and prevent accidental enlargement.
Quality and file-size controls. Set WebP quality or enter a maximum size in KB to find the highest quality that fits.
Before-and-after preview. Review the original and converted image, output dimensions, format, and file size.
File-size comparison. See the original and converted sizes and the percentage change.
Custom filename. Rename the converted file before downloading it.
Metadata-free export. The newly encoded WebP does not copy source metadata.

WebP works in modern browsers and may be supported by applications that cannot open AVIF.

Both formats are efficient, so conversion will not always reduce file size. Compare the result before replacing the source.

Transparent AVIF pixels remain transparent in WebP. Source metadata is not copied.

AVIF decoding depends on browser support. Unsupported AVIF features or damaged files may prevent conversion.

Is this AVIF to WebP converter free?

Yes. Convert one AVIF image at a time without an account.

Will transparency remain?

Yes. Transparent pixels are retained in WebP.

Is WebP always smaller?

No. AVIF is already efficient, and results vary with content and quality.

Is my image uploaded?

No. Conversion happens locally in your browser.

Why will my AVIF not open?

Your browser may not support the AVIF features used by that file.
