How much smaller will WebP be compared to BMP?
WebP can achieve 95-98% file size reduction compared to BMP. A 10MB BMP could become as small as 200-500KB in WebP lossy mode, or 1-2MB in lossless mode. It's the most efficient modern format.
Should I choose WebP lossy or lossless?
For photographs, lossy WebP provides the best size-to-quality ratio with nearly invisible quality loss. For screenshots, graphics, and images requiring pixel-perfect accuracy, choose lossless WebP.
Is WebP widely supported?
Yes. All modern browsers (Chrome, Firefox, Safari, Edge) support WebP. Most modern image editors and operating systems also handle WebP natively. Only very old software may lack support.
