HEIC
High Efficiency Image Container自 iOS 11 起 iPhone 默认拍摄使用的格式 —— 在相同质量下体积大约只有 JPEG 的一半，并支持深度图和实况照片。Windows 和大多数网站至今仍无法打开它，这也是为什么转换为 JPG 是需求量最大的图片转换。

关于 HEIC 转 TIFF 的常见问题
这个 HEIC 转 TIFF 转换器是免费的吗？
是的。在这里把 HEIC 转换为 TIFF 完全免费，无需账号、没有水印、也没有每日次数限制。处理在你自己的设备上完成，因此不存在需要转嫁给你的服务器成本。
我的 HEIC 文件会被上传到任何地方吗？
For browser-based pairs, your file is read locally and converted by Squoosh in this tab. No file payload is uploaded; you may still see analytics and engine downloads in network logs.
HEIC 转 TIFF 有文件大小限制吗？
There is no imposed upload cap when it runs in-browser, but each conversion still depends on your device and browser memory. Large videos are the first practical limit, then memory-heavy documents or images.
把 HEIC 转换为 TIFF 会损失质量吗？
It depends on your selected settings and codec path. Many engines can write either lossy or lossless output for TIFF, so you can usually increase quality if this file is your final version.
可以一次把多个 HEIC 文件转换为 TIFF 吗？
Yes. Drop in several files and each gets its own row; they are processed one after another on your device. You can download them one by one or as one ZIP.
HEIC 转 TIFF 能在手机、Mac 或 Chromebook 上使用吗？
Most modern browsers on Windows, macOS, Linux, ChromeOS, Android and iOS work. Very large videos are often more reliable on desktop or a browser with more memory.
Why do some conversions take longer on first run?
The conversion engine has to download first. Small codec bundles are fast, while ffmpeg is commonly 12–30 MB; later conversions of similar type use the cached engine.
I converted a file and the output is blank or unusable. What should I check?
Start over with default settings, then change one option at a time (quality, bitrate, page size, or codec) to isolate what changed behavior. If it keeps failing, retry with a smaller file and confirm the source format matches the pair.
