技術細節
AV1 編解碼器基金會
AVIF 是基於 AV1 視訊編解碼器構建，利用最初為視訊設計的先進幀內壓縮技術。與 JPEG 基於 DCT 的方法相比，這透過更好的預測演算法、變換編碼和熵編碼提供了卓越的壓縮效率。
高級色彩科學
JPEG 僅限於 8 位元 YUV 4:2:0 顏色取樣，而 AVIF 支援高達 12 位元顏色深度和 4:4:4 色度取樣。這可以實現更好的色彩準確度、減少色帶，並支援具有更寬色域的 HDR 內容，例如 Rec. 2020.
貨櫃結構
AVIF 使用 ISO 基本媒體檔案格式 (ISOBMFF) 容器，允許元資料儲存、多個影像序列和輔助影像資料。這比 JPEG 的簡單結構提供了更大的靈活性，同時保持對影像資料的高效隨機存取。

Frequently Asked Questions
What quality settings should I use when converting JPEG to AVIF?
For most images, an AVIF quality setting of 50-60 provides similar visual quality to JPEG at 85-90 quality but with 50-70% smaller file sizes. For photographs, quality 60-70 preserves fine details excellently while achieving significant compression gains.
Will converting JPEG to AVIF improve image quality?
Converting JPEG to AVIF won’t recover quality lost in the original JPEG compression, but AVIF’s superior algorithms often preserve existing quality better at smaller file sizes. You may see reduced compression artifacts and better color gradients in the AVIF version.
Which browsers and devices support AVIF format?
AVIF is supported by Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+. Mobile support includes Android 12+ and iOS 16+. While growing rapidly, consider providing JPEG fallbacks for older browsers.
How much smaller will my JPEG files become as AVIF?
AVIF typically achieves 50-90% smaller file sizes compared to equivalent quality JPEG images. Photographs with complex details see 50-70% reduction, while graphics and images with large uniform areas can achieve up to 90% size reduction.
Can AVIF handle transparency that JPEG cannot?
Yes, AVIF natively supports alpha channel transparency, making it an excellent replacement for PNG images as well. When converting JPEG to AVIF, no transparency is added, but the format capability is available for future editing.
Should I keep my original JPEG files after converting to AVIF?
It’s recommended to keep original JPEG files as master copies since AVIF browser support is still growing. Many websites serve AVIF to supported browsers with JPEG fallbacks for compatibility.
Does AVIF support the same metadata as JPEG files?
AVIF supports metadata storage including EXIF data, color profiles, and other image information from JPEG files. The conversion process can preserve camera settings, GPS coordinates, and other metadata embedded in your original JPEG images.
Is AVIF suitable for print materials like JPEG?
While AVIF offers superior quality and color depth capabilities, JPEG remains more universally supported for print workflows. AVIF is primarily optimized for digital display, though its enhanced color support makes it excellent for high-quality digital viewing before print conversion.
