About BMP
BMP is the device-independent bitmap format of Windows. It usually stores every pixel uncompressed.
Legacy Windows software, simple paint programs and embedded systems.
Without compression a BMP is many times larger than a PNG of the same image.
Convert BMP to WebP online free, no account required — WebP is Google's web image format with lossy or lossless compression.
Change BMP to WebP without losing quality — convert BMP to WebP free in your browser.
Why is my BMP file so enormous compared to the same picture as PNG? The Windows bitmap stores pixels raw with no compression at all, so even a small screenshot can weigh megabytes that PNG stores in kilobytes.
About WebP
WebP is an image format released by Google in 2010. It supports lossy and lossless compression, transparency and animation.
Websites use it to serve images smaller than the equivalent JPEG or PNG; all current browsers display it.
Some older desktop software and many print services still do not accept WebP files.
Why convert images to WebP? It cuts file sizes by a quarter to a third compared with JPG at the same quality, and every current browser displays it.
What changes when you convert BMP to WebP
- The BMP picture is re-encoded as WebP at the default quality settings, so it looks close to the original but is not bit-identical.
Settings you can change
Before you convert BMP to WebP, you can adjust: Width, Height, Scale fit, Crop position, Never enlarge, Quality, Lossless, Progressive, Remove metadata, Auto-orient from EXIF, Rotate, and Background.
Limits
Each plan sets a maximum file size and a number of conversions per day, and video and audio files also have a maximum length. Guests can convert files up to 100 megabytes and 5 per day; a free account raises this to 500 megabytes and 25 per day; paid plans go up to 100 gigabytes.
Your converted WebP file is kept for 2 hours, then deleted.
