How do I convert JPG to AVIF?

Select or drag and drop your JPG image onto the upload area, adjust the quality slider if needed, click 'Convert to AVIF', then download your converted AVIF image.

What quality level should I choose for AVIF conversion?

For most web images, a quality setting between 75–85 provides an excellent balance between quality and file size. For photos with fine details or where maximum quality is required, 90–95 is recommended.

Will I lose quality when converting from JPG to AVIF?

AVIF is a lossy format like JPG, but it provides better quality at the same file size. In most cases you'll get better quality with AVIF compared to the original JPG at similar or smaller file sizes.

AVIF (AV1 Image File Format) is a modern image format that offers superior compression and quality compared to older formats like JPEG and PNG, using the AV1 video codec to achieve smaller file sizes.

What are the advantages of AVIF over JPEG?

AVIF provides significantly better compression (up to 50% smaller files than JPEG at similar quality), supports transparency, has better color depth, and supports both lossy and lossless compression — resulting in faster web pages and lower bandwidth usage.
