Why convert TIFF to BMP?
- BMP is made for older Windows programs, embedded devices and tools that need raw pixels.
- BMP needs no decoding, so very simple or older software can display it.
What to expect when converting TIFF 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）。
- Expect a bigger file: BMP usually takes more space than TIFF for the same picture.
- 多页 TIFF 只会转换第一页，CMYK 印刷色彩会转为标准 RGB。

- 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）。
