AVIF 转 JPG 转换器
将 AVIF 图像转换为通用兼容的 JPG 格式。AVIF 是最佳网页格式,但缺乏软件支持——JPG 在任何地方都能使用。免费、即时、隐私保障。
什么是 AVIF?
AVIF(AV1 图像文件格式)是一种基于 AV1 视频编解码器的下一代图像格式。它在相同质量下比 JPEG 压缩率高出约 50%,比 WebP 高出约 20%。然而,AVIF 仍是较新的标准,除网页浏览器外的软件支持有限——Photoshop 于 2021 年才加入对 AVIF 的支持,许多其他工具仍无法打开 AVIF 文件。
何时将 AVIF 转换为 JPG
当您需要在不支持 AVIF 的软件中打开图像(如旧版 Photoshop、Lightroom、许多图像查看器)、通过电子邮件或聊天应用分享、上传到不接受 AVIF 的平台,或在要求 JPEG 输入的打印实验室打印时,将 AVIF 转换为 JPG。
AVIF 输入的浏览器要求
AVIF 解码需要 Chrome 85+、Firefox 93+ 或 Safari 16+。如果使用较旧的浏览器,AVIF 文件可能无法在工具中加载。遇到问题请升级浏览器,或使用桌面应用程序进行转换。
常见问题
AVIF is a relatively new format (standardized in 2019) and desktop software support is still catching up. Windows 10 requires a codec update, older Photoshop versions don't support it, and most image viewers don't recognize AVIF yet. Converting to JPG instantly makes the image compatible with all software.
Yes - AVIF achieves 50% better compression than JPEG, so the JPEG output will typically be 50–100% larger than the AVIF source at equivalent quality. For example, a 200 KB AVIF at quality 80 might become a 400–450 KB JPEG at quality 90.
AVIF input decoding requires Chrome 85+, Firefox 93+, or Safari 16+. Older browsers cannot decode AVIF files. The tool will display an error if your browser lacks AVIF support. Update your browser to the latest version if you encounter issues.
Keep your original AVIFs if file size matters - they're your smallest copy. Use the JPEG versions only for compatibility purposes (sharing, printing, software that doesn't support AVIF). AVIF is the right archival format if your workflow supports it.
