What this HEIC 转 JPG tool is planned to do
此服务器工具会解码你的 HEIC 文件，并生成静态的 JPG 图像。只导出第一张图像或第一帧。会应用图像方向，并移除元数据。输出 JPG 时，透明像素会与白色背景合并，并可能带来压缩损失。
何时使用 HEIC 和 JPG / JPEG
从 iPhone 或其他采用 HEIF 图像存储的设备中转移照片时，常会遇到 HEIC。 手机照片、照片图库，以及从受支持设备分享的相机图像。
JPG 是一种得到广泛支持的图像格式，在照片质量和较小的文件体积之间取得平衡。 JPG 不支持透明背景。再次以有损压缩保存可能丢失细节；转换为 PNG 也无法找回这些细节。
处理与限制
Our HEIC tool is planned but unavailable. Our current design would use server processing; its privacy behaviour and limits will be explained before launch.
This conversion needs server processing, which is not available yet. It is planned, and nothing can be uploaded to ConvertMango for this tool at present. Before it is offered we will publish how files are handled, including the limits and how long they are kept.

放入文件之前。
Are my files uploaded?
The tools available now run in your browser, and the contents of your files are not uploaded to our conversion service. Audio, video and advanced document tools would need server processing; they are planned, shown as not available yet, and cannot be used at present.
任何文件都能转换成其他任意格式吗？
No. Only supported pairs are offered, and the pairs marked as not available yet cannot be used today. When available, MP3 to MP4 will create a static-background video using your audio, PDF to Word will extract editable text without preserving original fonts, images or complex layouts, and PDF to Excel will extract structured tables, not entire page designs.
免费吗？
Yes. The free allowance is five successful conversions a day, resetting at 00:00 UTC, and you do not need to sign in. A conversion only counts when it succeeds, and downloading a result again does not count again.
转换会提升质量吗？
更改格式无法找回之前已丢失的细节。重新编码音频、视频或 JPG 文件可能降低质量。请保留原文件，并在使用前检查转换结果。
