Why AVIF files can still be large
AVIF is efficient, but large dimensions, high-quality exports, and detailed images can still produce files that are too heavy for upload forms or website delivery.
Reduce AVIF file size with quality settings
Lower quality settings can reduce AVIF file size. Start near the default quality for a clear result, then lower it only when a smaller file matters more than fine detail.
Resize AVIF images before upload
If an AVIF image is larger than the final display size, use Max side to reduce dimensions. Resizing often saves more bytes than compression alone.
AVIF vs WebP for smaller files
AVIF can be smaller than WebP for some images, but WebP is more broadly compatible and faster to encode. Use AVIF when modern browser delivery is your priority.

FAQ
Can AVIF be compressed more?
Yes. AVIF can often be reduced further by lowering quality or resizing oversized dimensions.
Why is my AVIF file still large?
High detail, large dimensions, and high quality settings can keep AVIF files large even though AVIF is an efficient format.
Should I resize AVIF images?
Yes, if the image dimensions are much larger than needed. Resizing is often the most effective way to reduce AVIF file size.
Is WebP smaller than AVIF?
Sometimes WebP is larger, sometimes the difference is small. AVIF often wins on file size, while WebP is usually faster and more compatible.
