BMP vs. WEBP: Technical Comparison
Understanding the technical differences between BMP and WEBP helps you decide when conversion is beneficial and what to expect from the output.
- BMP: None (uncompressed) compression | No transparency | Very large (uncompressed pixel data)
- WEBP: Lossy and Lossless compression | Supports transparency | 25-35% smaller than JPEG at equivalent quality
- BMP introduced: 1986 by Microsoft
- WEBP introduced: 2010 by Google
- BMP best for: legacy Windows applications, simple image storage
- WEBP best for: web images, page speed optimization, modern web design
BMP uses none (uncompressed) compression while WEBP uses lossy and lossless compression. Both support lossy and lossless modes.
100% Private: No File Uploads
Your images often contain personal photos, proprietary designs, confidential screenshots, or sensitive visual data. Uploading these to a cloud-based converter exposes them to third-party servers where they might be stored, logged, or accessed by unauthorized personnel. Our tool eliminates this risk entirely. The conversion uses your browser's native Canvas API and FileReader API — everything runs in client-side JavaScript. You can verify this by checking the Network tab in your browser's DevTools during conversion. You will see zero outbound requests. For maximum confidence, you can even disconnect from the internet after loading the page and the conversion will still work perfectly.
Your images are processed entirely on your device using the browser's Canvas API. No files are uploaded to any server. You can disconnect from the internet and the converter will still work.
