What is AVIF?
AVIF is a modern image format based on the AV1 video codec. It compresses even better than WebP and supports transparency and HDR, and it is now common on large websites and CDNs. AVIF is best for very small, high-quality images on modern websites. Many editors, older browsers, office software and upload forms do not accept AVIF yet.
What is JPG?
JPG (also written JPEG) is the most widely supported photo format. It uses lossy compression tuned for photographs, which keeps files small, but it has no transparency. JPG is best for photos, e-mail attachments, social media and any upload form.
When should you convert AVIF to JPG?
- An upload form, marketplace or e-mail client does not accept AVIF.
- You want to print or share an image saved from a modern website.
- You need a small, universally compatible photo.
Tips for the best result
Transparent areas become the background colour you choose (white by default). A quality of 85–90 % keeps the photo looking like the AVIF.
