Frequently Asked Questions
How much smaller will a BMP file be as WebP?
WebP files are typically 95-99% smaller than BMP files. A 30MB BMP could become as small as 300KB-1MB as a WebP file, depending on the quality setting and image content.
Can I choose between lossy and lossless WebP?
Yes. Use the quality slider to control compression. A quality of 100% gives near-lossless results that preserve every detail, while lower values apply lossy compression for even smaller files.
Is WebP supported everywhere?
WebP is supported by all modern browsers and most image editing applications. Support exceeds 97% of global browser users. For legacy systems, consider converting to JPG or PNG instead.
Will transparency be preserved from BMP to WebP?
If your BMP has an alpha channel (32-bit BMP), it will be preserved in the WebP output. WebP supports full alpha transparency, unlike JPG.
Is this BMP to WebP converter free and private?
Yes. The converter is completely free with no limits. All processing happens in your browser, so your BMP files are never uploaded to any server.
How It Works
This converter uses your browser's built-in Canvas API to process files locally. Your BMP files are decoded and re-encoded as WebP entirely on your device. Nothing is uploaded to any server.
