How to convert JPG to AVIF

Choose a JPG or JPEG, adjust the AVIF settings, and download the result when browser encoding is supported.

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 JPG to AVIF 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 AVIF 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 AVIF does not copy source metadata.

AVIF can produce compact files at strong visual quality, making it useful for modern websites and image-heavy pages.

Re-encoding cannot restore detail already lost from the JPG. Compare the preview carefully to avoid unnecessary additional compression.

AVIF encoding is supplied by the browser and is not available everywhere. If export is unsupported, try a current browser or use WebP.

Modern browsers display AVIF, but some older applications do not. The output does not copy JPG metadata.

Is this JPG to AVIF converter free?

Yes. Convert one JPG at a time without an account.

Why is AVIF export unsupported?

Your browser may display AVIF without providing an AVIF encoder.

Will AVIF always be smaller?

Not always. Size depends on the source, dimensions, content, and selected quality.

Can I target a file size?

Yes. Enter a maximum in KB and the tool searches available quality levels.

Is JPG metadata copied?

No. The AVIF is newly encoded without source metadata.
