Converting BMP to WEBP is a common task when you need smaller than jpg/png at the same quality. BMP (Bitmap) is an old, typically uncompressed Windows raster format. It stores raw pixel data, so quality is perfect but files are enormous — which is why converting BMP to PNG, JPG or WebP is so common. WEBP, on the other hand, gives you smaller than jpg/png at the same quality and supports transparency. ZeroUpload performs this conversion entirely inside your browser, so your BMP file is never uploaded to a server.

When should you convert BMP to WEBP?
You should convert BMP to WEBP when you want speeding up website load times but your source is BMP. Typical situations include exporting from legacy Windows software, raw pixel-perfect intermediates, where the destination expects WEBP instead.
BMP vs WEBP
Bitmap Image (BMP)
BMP (Bitmap) is an old, typically uncompressed Windows raster format. It stores raw pixel data, so quality is perfect but files are enormous — which is why converting BMP to PNG, JPG or WebP is so common.
Strengths
- + Lossless, raw pixels
- + Simple, well-documented
Trade-offs
- – Huge file sizes
- – No real web support
- – No compression
WebP Image (WEBP)
WebP is a modern Google format with both lossy and lossless modes. At equal quality it is typically 25–35% smaller than JPG or PNG, supports transparency, and is now backed by every major browser.
Strengths
- + Smaller than JPG/PNG at the same quality
- + Supports transparency
- + Modern browser support
Trade-offs
- – Less universal in old desktop apps
- – Occasionally rejected by legacy tools

What is the difference between BMP and WEBP? +
BMP is an uncompressed raster format that stores pixel data with maximum fidelity. WEBP is a modern Google format offering superior compression and smaller file sizes for the web. Converting from BMP to WEBP trades lossless, raw pixels for smaller than jpg/png at the same quality.
