Generation loss — quality may degrade
HEIC uses lossy compression and AVIF typically uses lossy mode. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Default format on iPhone 7+ (iOS 11+)
Your device saves files in HEIC by default (iPhone 7+ (iOS 11+), iPad Pro 2017+, macOS High Sierra+). Most people convert because the files won't open on other devices — AVIF is universally supported and will work everywhere.
您是否曾苦恼于iPhone拍摄的HEIC照片在其他设备上无法直接查看？或者在社交媒体分享时，发现它们占据了大量存储空间？HEIC格式虽然高效，但在兼容性和通用性方面，有时确实会给我们的日常数字生活带来不便。而AVIF，作为一种新兴的图片格式，以其卓越的压缩效率和出色的图像质量，正逐渐成为主流。它不仅能让您的照片文件更小巧，加载速度更快，还能保持细节不失真。现在，是时候让您的HEIC照片焕发新生，轻松转换成兼容性更广、性能更优异的AVIF格式了。
