Why convert HEIF to BMP?
- BMP is supported far more widely than HEIF, so the file is easier to open, share and upload.
- BMP is lossless, so the converted image loses no further detail when you edit and save it again.
- BMP is made for older Windows programs, embedded devices and tools that need raw pixels.
What to expect when converting HEIF to BMP
- 转换无法找回 HEIF 压缩已去除的细节：BMP 是图像现状的精确副本，文件通常更大。
- 高动态范围和广色域细节会转换为标准 8 位色彩。

| 动画 | 否 | 否 |
| 颜色 | 每通道 8 或 10 位，广色域 | 1670 万种颜色（24 位） |
| 可用什么打开 | Recent phones and cameras; many PCs, apps and websites need extra software | Windows and macOS apps, older software and browsers |
| 最适合 | storing high-quality photos in less space on phones and cameras | older Windows programs, embedded devices and tools that need raw pixels |
