Why convert BMP to WebP?
- WebP files are usually smaller than BMP for the same picture, so pages load faster and uploads finish sooner.
- WebP is made for websites, online stores and blogs that need fast-loading images.
What to expect when converting BMP to WebP
- WebP uses lossy compression by default; raise the quality or switch on lossless in Settings for a closer copy.
- Your original BMP file isn’t changed: you download a new WebP copy.
BMP vs WebP

| Origin | Created by Microsoft for Windows | Released by Google in 2010 |

| Transparency | No (in the 24-bit BMPs most apps read) | Yes — smooth, partial transparency |
| 动画 | 否 | 是 |
| 颜色 | 16.7 million colours (24-bit) | 8 bits per channel |
| Where it opens | Windows and macOS apps, older software and browsers | All current browsers; some older desktop apps and upload forms reject it |
| 最适合 | older Windows programs, embedded devices and tools that need raw pixels | websites, online stores and blogs that need fast-loading images |
