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.
- 您原来的 BMP 文件不会被更改：您下载的是一份新的 WebP 副本。
