Nén AVIF — miễn phí trực tuyến, không tải lên
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.
Codec details on /formats/#avif.
Cách nén AVIF
- 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.
Khi nào chuyển đổi thay vì nén
Nếu AVIF không được chấp nhận, tải JPEG hoặc WebP từ cùng hàng. Xem AVIF sang JPG hoặc AVIF sang WebP.
Câu hỏi thường gặp
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.
