Why convert HEIC to BMP?
- BMP is supported far more widely than HEIC, 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 HEIC to BMP
- 转换无法找回 HEIC 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。
