Three things it keeps三样都留住

Most converters give up at least one别的工具往往至少丢掉一样

01 · Cover frame封面帧

The frame you chose还是你选的那一帧

Matched to the exact frame by its original timestamp按原时间戳对齐到对应的那一帧
Missing timing is reported, never guessed时间信息缺失会直接提示，不拿中间帧凑数
Want it sharper? Some photos offer high-res candidate frames, with the motion unchanged想更清晰？部分照片可改选高清候选帧，动态不变

02 · Quality画质

Video never re-encoded视频不重新编码

Original audio and video samples, just rewrapped原始音视频数据直接重新封装
Checked sample by sample before output输出前逐个样本校验
Apple HEIC → Android JPEG re-encodes the still: different format, and Android’s HEIC support is limited苹果 HEIC 转安卓 JPEG 时，静态图需重新编码：格式不同，且安卓对 HEIC 支持有限

03 · HDRHDR

Kept, or clearly flagged能留的都留，留不了就说明

Ultra HDR gain maps kept with their parametersUltra HDR 增益图连同参数保留
Unsupported HDR is flagged, never faked不支持的 HDR 会标出，不假装转好
Apple gain maps converted for Android may not be bit-exact苹果增益图转成安卓格式时，可能无法完全无损
High-res candidate frames carry no HDR gain map高清候选帧不含 HDR 增益图

FAQ常见问题

Can’t I just copy the file to my iPhone?直接拷到 iPhone 不行吗？

No — the formats differ, so it shows up as a still photo不行，格式不同，拷过去只是一张静态图

Will I lose quality?会掉画质吗？

Video and audio: never — they’re rewrapped and verified. Android → iPhone keeps the photo as is; if you pick a high-res candidate cover instead, that frame is decoded to JPEG without the original HDR. iPhone HEIC → Android JPEG must re-encode the still (Android’s HEIC support is limited), and the HDR gain map may not carry over losslessly视频和音频不会，只重新封装并校验。安卓转 iPhone，照片原样保留；若改选高清候选封面，该帧会解码为 JPEG，不带原封面的 HDR；iPhone 的 HEIC 转安卓 JPEG，静态图必须重新编码（安卓对 HEIC 支持有限），HDR 增益图也可能无法完全无损

Are my photos uploaded?照片会上传吗？

No. Everything happens on your Mac不会，全程在你的 Mac 本地完成

Can I convert back to Android?能转回安卓吗？

Yes. Choose Apple → Android and the recipient’s phone brand可以，选择「Apple → Android」和对方手机品牌即可

Is it free?收费吗？

Yes, free and open source (GPL-3.0). Sponsoring on GitHub is welcome, never required免费开源（GPL-3.0），觉得好用，欢迎在 GitHub 赞助
