Frequently Asked Questions
At quality 80, expect 95-98% reduction. A 10MB BMP typically becomes 200-500KB in WebP.
Converting directly from BMP to WebP avoids any intermediate quality loss from a two-step process. Going BMP to JPG to WebP would apply lossy compression twice. Direct conversion gives you the best possible WebP output from the raw source.
BMP to WebP achieves one of the highest compression ratios of any conversion. A 24-bit BMP at 1920x1080 is always 5.9MB, but the same image as a WebP at quality 80 is typically 150-400KB — a 15:1 to 40:1 compression ratio depending on image complexity.
Yes, you can choose lossless WebP compression to preserve every pixel from the BMP source. Lossless WebP files are larger than lossy but still 50-70% smaller than the original BMP, making them a great middle ground between quality and size.
