Compressing AVIF to Under 50 KB
AVIF excels at aggressive budgets, so 50 KB (around Q74) yields surprisingly clean mobile thumbnails and social cards. Where JPEG would show heavy blocking, AVIF keeps edges and gradients smoother. This target fits mobile-first image grids, avatars, and previews. Encoding takes longer, but the quality-per-byte advantage is largest precisely at these small sizes. Resize to about 1280 px when the source is large.

Frequently Asked Questions
Why does AVIF look cleaner than JPEG at 50 KB?
AVIF uses modern coding tools (prediction, transforms) that avoid the 8×8 blocking artifacts JPEG suffers from at low bitrates.
Is AVIF worth the slower encoding for thumbnails?
For large galleries where bytes add up, yes. For a handful of images, WebP may be more practical due to faster encoding.
