Compressing AVIF to Under 20 KB
The 20 KB AVIF target (around Q68, ~800 px) is where the format pulls furthest ahead: it preserves more recognizable detail than JPEG or even WebP at this extreme. Use it for tiny thumbnails, low-bandwidth previews, and placeholders. Some smoothness loss is unavoidable, but AVIF avoids the harsh blocking of JPEG. Pair with a WebP fallback for older clients, and reserve this budget for genuinely small display sizes.

Frequently Asked Questions
Is AVIF the best format for 20 KB images?
For quality at tiny sizes, generally yes. It beats JPEG clearly and often edges WebP, though WebP remains a safer compatibility fallback.
Will an old Safari show my 20 KB AVIF?
Older Safari versions before AVIF support (pre-16.4) will not render it. Provide a WebP or JPEG fallback if you need to cover them.
