Why Convert BMP to WebP?

WebP gives the best of both worlds for old bitmaps: lossless or high-quality lossy compression with modern browser support, turning huge BMP files into fast-loading web assets.

Common use cases

  • You have a BMP file and need it in WebP format for optimising images for faster web performance.
  • The target software or platform requires WebP but your file is in BMP.
  • You want to reduce file size or improve compatibility without using desktop software.
Keep in mind: Older versions of Safari and some legacy apps have limited WebP support, though compatibility is now near-universal in modern browsers.

How to Convert BMP to WebP

  1. Upload or drop your BMP file into the converter above.
  2. Adjust any output settings for WebP if needed.

About the Formats

BMP (Bitmap Image File)

BMP is an uncompressed raster format from the early days of Windows. Every pixel is stored without compression, which makes BMP files large but completely lossless and trivially simple to read — the reason it survives in embedded systems, scanners, and legacy Windows software.

Compatibility: Supported by all major browsers, Windows, macOS, and virtually every image editor.

WebP (Web Picture Format)

WebP is a modern image format developed by Google for the web. It delivers superior lossless and lossy compression compared to PNG and JPG — WebP images are typically 25–35% smaller than equivalent JPGs at the same visual quality — while also supporting transparency and animation.

Compatibility: Chrome, Firefox, Edge, Safari 14+, and most modern applications.
