Why convert BMP to PDF?
- PDF is supported far more widely than BMP, so the file is easier to open, share and upload.
- The PDF page is sized to your image, so it prints and previews without cropping or extra borders.
What to expect when converting BMP to PDF
- You get one page per image, with the picture embedded as a high-quality JPEG. To combine several images into one PDF, use the Image to PDF tool.
- Your original BMP file isn’t changed: you download a new PDF copy.
BMP vs PDF
| 功能 | BMP | |
|---|---|---|
| 全名 | Windows Bitmap | Portable Document Format |
| Origin | Created by Microsoft for Windows | Created by Adobe in 1993; an ISO standard since 2008 |
| 压缩 | Uncompressed | Document page with the image embedded at high quality |
| Transparency | No (in the 24-bit BMPs most apps read) | No — transparent areas get a solid background |
| 动画 | 否 | 否 |
| 颜色 | 16.7 million colours (24-bit) | Full colour |
| Where it opens | Windows and macOS apps, older software and browsers | Built-in viewers in browsers, phones and computers |
| 最适合 | older Windows programs, embedded devices and tools that need raw pixels | emailing, printing and attaching images to forms and applications |
| Main drawback | very large files and no transparency | the picture isn’t editable as an image until you convert it back |
In short: choose BMP for older Windows programs, embedded devices and tools that need raw pixels; choose PDF for emailing, printing and attaching images to forms and applications.
