Why convert GIF 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 GIF to BMP
- BMP 无法存储透明度，因此透明区域会用您在“设置”中选择的背景色填充（默认为白色）。
- BMP 无法保存此动画，因此动态 GIF 会保存为其第一帧。
- 转换无法找回 GIF 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。

|---|---|---|
| 全名 | Graphics Interchange Format | Windows 位图 |

| 压缩 | 无损，但仅限 256 种颜色 | 未压缩 |
| 透明度 | 只有开/关（一种透明色） | No (in the 24-bit BMPs most apps read) |
| 动画 | 是 | 否 |
| 颜色 | 每帧最多 256 种颜色 | 1670 万种颜色（24 位） |
| 可用什么打开 | All browsers, email apps and messaging apps | Windows and macOS apps, older software and browsers |

- 质量滑块范围: 20–100 · 默认: 90
- For JPG, WebP, AVIF and image-to-PDF output: higher keeps more detail but makes a bigger file; 60–80 suits most photos. Documents (Publisher, XPS, EPS…) become PDFs with every page and sharp text, with no quality setting.
- 无损模式开／关
- For WebP and AVIF output: keeps every pixel exactly (best for logos, graphics and transparency) at the cost of a larger file.
- 背景填充取色器
- 适用于无法存储透明度的 JPG、BMP 和图片转 PDF 输出：用于填充透明区域的颜色（默认为白色）。
模式
