About BMP and WebP
- BMP
- BMP is the simple, uncompressed Windows bitmap format. Files are large, but almost any program can open them, including very old ones.
- WebP
- WebP is a modern web image format from Google. It makes smaller files than JPG or PNG at similar quality, supports transparency, and opens in every current browser.
Frequently asked questions
Is the BMP to WebP converter free?
Yes. You can convert 3 files every 24 hours for free, without an account. Pro removes the daily limit.
Are my BMP files uploaded to a server?
No. The conversion runs in your browser with standard web technology, and the file never leaves your device.
Will the WebP file lose quality?
WebP uses lossy compression. At the default quality of 90% the difference is hard to see; set it to 100% for maximum detail.
Can I convert several files at once?
Yes. Add as many files as you like and they are converted one after another. Pro runs up to 3 at the same time and can download all results as one ZIP.
Does it work on my phone?
Yes, in any up-to-date browser. Phones have less memory, so very large files may need a computer.
