AVIF 압축 — 무료 온라인, 업로드 없음
Drop an AVIF into PicBrewery and download a smaller AVIF re-encoded in your browser. AVIF is already compact — re-tuning encoder settings and stripping metadata can still shave bytes.

AVIF 압축 방법
- Open PicBrewery.
- Drop your
.aviffile (or several) on the drop zone. - Wait for encoding — AVIF is CPU-heavy. Download from the AVIF column when it appears.
- Use Download all as ZIP for batches.
AVIF re-encoding in the browser
PicBrewery uses libavif (AOM AV1 encoder) compiled to WebAssembly. Re-encoding at tuned quality and stripping metadata can reduce file size 5–15% on already-compressed AVIFs.
Encode time is slower than JPEG or WebP — expect a few seconds per megapixel on typical hardware.

자주 묻는 질문
Does compressing AVIF lose quality?
Lossy AVIF re-encode is lossy. Adjust quality under Advanced settings if you need higher fidelity.
Why is AVIF encoding slow?
AV1 compression is CPU-intensive. PicBrewery runs libavif in Web Workers, but a megapixel image can take 1–3 seconds or more.
Will alpha transparency survive?
Yes — AVIF alpha is preserved in the AVIF output column.
Can I batch-compress AVIF files?
Yes — up to 20 files per batch with ZIP download.
Does PicBrewery resize AVIF images?
No — same dimensions, re-encode only.
