Jak skompresować AVIF

  1. Otwórz PicBrewery.
  2. Drop your .avif file (or several) on the drop zone.
  3. Wait for encoding — AVIF is CPU-heavy. Download from the AVIF column when it appears.
  4. 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.

Kiedy konwertować zamiast kompresować

Gdy platforma nie akceptuje AVIF, pobierz JPEG lub WebP z tego samego wiersza. Zobacz AVIF do JPG lub AVIF do WebP.

Często zadawane pytania

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.
