Even WebP Is Leaving Bytes on the Table
If speed is the goal, AVIF squeezes your images further than any format before it.
Images Still Too Heavy
You converted to WebP and pages got faster - but AVIF goes further, shaving off roughly another 20% at the same visual quality. That's weight your visitors are still downloading.
AVIF is ~50% smaller than JPEGSpeed Scores Plateau
Once the easy wins are gone, the last stretch of Core Web Vitals is the hardest. Serving the smallest possible format is one of the few levers left to pull.
~20% smaller than WebP, at equal qualityAVIF Locked Behind Cloud Credits
Most plugins gate AVIF behind metered cloud plans that charge per image or per month. Convert enough and the "next-gen" upgrade turns into a recurring bill.
No per-image fees, runs on your serverHow AVIF Conversion Works
The same safe, in-place conversion as WebP - now in the smallest format available.
Convert
ThumbPress writes a smaller AVIF version first, raising the memory limit and pre-flighting available RAM so large images convert safely.
Rewrite
It rewrites stored URLs across post content, meta and options - including WooCommerce - so every reference points at the new AVIF file.
Replace
The old file is deleted only after the new one is safely written, so a failed conversion can never leave you with a broken image.
