About the BMP format
BMP (Bitmap) is the uncompressed raster format of Windows. Every pixel is stored as is, so the quality is perfect but the files are enormous: a 12 megapixel photo takes about 36 MB. It has no transparency in common use and is rarely accepted by websites or messaging apps.
About the WebP format
WebP is Google's modern image format, supported by every current browser. It compresses photos 25 to 35 percent better than JPG at the same quality, supports transparency like PNG and animation like GIF, and comes in lossy and lossless flavours. Its only drawback is older software that cannot open it.
Frequently asked questions
Why convert BMP to WebP?
WebP makes the smallest files of any widely supported format while keeping transparency, so pages load faster with no visible change. BMP files are uncompressed and therefore huge, and most websites and apps will not accept them.
Does converting BMP to WebP lose quality?
WebP uses lossy compression, so a little detail is discarded to make the file smaller. At 85 percent quality or higher the difference is invisible for most images, and you can push the slider to 100 for maximum fidelity.
Can I convert several BMP files at once?
Yes. Add up to 5 images of up to 30 MB each, convert them in one go, and download the results one by one or all together as a ZIP.
Are my BMP images uploaded anywhere?
No. The conversion runs entirely in your browser, on your own device. Nothing is sent to any server, so your pictures never leave your computer or phone.
Is the BMP to WebP converter free?
Yes, completely. No account, no watermark, and no limit beyond 30 MB per image. PixKit is supported by ads.
