HEIC 转 JPG 转换器
将 iPhone HEIC 照片转换为通用兼容的 JPEG 格式。可在 Apple 设备的 Safari 中使用。免费,无需上传,完全私密。
什么是 HEIC,为什么 Windows 打不开它?
HEIC(高效图像容器)是 Apple 自 iOS 11 起在 iPhone 和 iPad 上默认使用的照片格式。它采用 HEVC(H.265)压缩,在相同质量下文件大小约比 JPEG 小 50%。然而,Windows 10(除非安装付费解码器)、大多数 Android 设备以及许多桌面应用都不原生支持 HEIC。
浏览器对 HEIC 转换的支持情况
重要提示: HEIC 解码需要平台级支持。此工具在 macOS 或 iOS 的 Safari 中使用时可以转换 HEIC 文件,因为 Apple 操作系统自带 HEIC 编解码器。在 Windows 或 Android 上,浏览器无法解码 HEIC 文件——此时会出现错误。Windows 用户最可靠的做法是直接在 iPhone 上启用 HEIC 兼容模式(设置 → 相机 → 格式 → 最兼容)。
可选方案:在 iPhone 上直接转换 HEIC
Windows 用户最简便的解决方案是将 iPhone 设置为拍摄 JPEG 而非 HEIC:前往 设置 → 相机 → 格式 → 选择“最兼容”。这样照片会自动保存为 JPEG,根本不需要再转换。
常见问题
HEIC decoding requires the HEVC codec which is built into Apple's operating system (macOS and iOS) but not available in Windows browsers by default. This tool works correctly in Safari on Mac or iPhone. For Windows, the simplest solutions are: (1) use the iPhone's "Most Compatible" camera setting to shoot JPEG instead, (2) use Apple's iCloud.com to download photos as JPEG, or (3) install the HEIF Image Extensions from the Microsoft Store.
Open this page in Safari on your iPhone, then tap the upload button and select your HEIC photo from Photos. The tool will convert it to JPG in your browser. Alternatively, you can AirDrop the HEIC to a Mac and convert it there. The simplest long-term fix is to set your camera to shoot in JPEG: Settings → Camera → Formats → Most Compatible.
Yes - HEIC achieves the same visual quality as JPEG at roughly half the file size, thanks to the more efficient HEVC codec. However, this efficiency comes at the cost of compatibility. For photos you want to share widely or use in non-Apple software, converting to JPG is the practical choice.
Some quality loss occurs because JPEG uses a different, less efficient compression algorithm. At quality 92 (this tool's default), the JPEG output is visually excellent and the loss is imperceptible under normal viewing conditions. Only at very high zoom levels on detailed photos might you notice subtle differences.
