JPG to AVIF is the smallest path for photos — 30–50% smaller than JPG at the same look, with HDR and 10-bit where you need it. Convert locally, no server.
AVIF encode is slower, you do it once on your PC.
Folder or files, subfolders kept. No upload.
Quality 40–95, HDR auto where supported.
All threads, write AVIF next to originals.
AVIF is the densest delivery codec for photos — smaller than WebP at the same visual quality, with 10-bit and HDR.
30–50% smaller than JPG, 15–25% smaller than WebP — at a slower encode you pay once.
For web hero images and portfolios where every kilobyte matters, JPG → AVIF saves the most. WebP is faster and more compatible; AVIF is smallest. Compressy lets you output both in one batch — JPG → WebP + JPG → AVIF — and compare side-by-side before you ship. All encode stays on your disk.
AVIF not in this 3-config run; WebP real numbers are baseline.
AVIF encode is slower — batch on 4/8 threads to hide the cost. Quality 75–85 is visually near-lossless.
