Why convert JFIF to BMP?
- 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 JFIF to BMP
- 转换无法找回 JFIF 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。
- 您原来的 JFIF 文件不会被更改：您下载的是一份新的 BMP 副本。
JFIF 与 BMP 对比
| 功能 | JFIF | BMP |
|---|---|---|
| 全名 | JPEG File Interchange Format | Windows 位图 |
| 来源 | Defined in 1992 as the standard JPEG file layout | Created by Microsoft for Windows |
| 压缩 | 有损（它就是 JPEG） | 未压缩 |
| 透明度 | 否 | No (in the 24-bit BMPs most apps read) |
| 动画 | 否 | 否 |
| 颜色 | 1670 万种颜色（每通道 8 位） | 1670 万种颜色（24 位） |
| 可用什么打开 | Most image viewers, but many upload forms reject the .jfif extension | Windows and macOS apps, older software and browsers |
| 最适合 | 没有 JPG 做不到的——它保存的是相同的图像数据 | older Windows programs, embedded devices and tools that need raw pixels |
| 主要缺点 | upload forms and some apps reject the .jfif extension | very large files and no transparency |
In short: choose JFIF for nothing a JPG can't do — it holds the same image data; choose BMP for older Windows programs, embedded devices and tools that need raw pixels.
