WebP to BMP Converter

Convert WebP images to BMP (Bitmap) format for maximum compatibility with legacy software and applications. BMP is an uncompressed format supported by virtually all image editors. Need other formats? Try our WebP to PNG or WebP to JPG converters.

How to Convert WebP to BMP

  1. Upload your WebP images by dragging and dropping or clicking the upload area. You can select up to 10 files at once for batch conversion.
  2. Choose color depth: Select 24-bit for standard BMP without transparency, or 32-bit to preserve alpha channels (limited software support).
  3. Set background color: For 24-bit BMP, choose a background color to replace transparent areas in your WebP images.
  4. Optional resizing: Enable resize options to change dimensions during conversion using our image resizer technology.
  5. Convert and download: Click convert and download individual files or all as a ZIP archive.
Pro tip: Use our WebP Analyzer first to check if your image has transparency. If not, 24-bit BMP is the best choice for compatibility.

WebP vs BMP Comparison

WebP

Modern image format by Google with excellent compression. Supports both lossy and lossless compression, transparency, and animation. Ideal for web use but may not be compatible with older software. Convert to other formats using our WebP converters.

BMP

Bitmap format with no compression, resulting in larger file sizes but universal compatibility. Supported by virtually all image editors and applications since Windows 3.0. Best for legacy software, simple graphics, or when you need raw pixel data.

Understanding Color Depth

24-bit BMP

Maximum compatibility. Uses 8 bits each for red, green, and blue channels (16.7 million colors). No transparency support - transparent areas are filled with your chosen background color. Works with all software that supports BMP.

32-bit BMP

Preserves transparency. Adds an 8-bit alpha channel to store transparency data. However, many applications don't support 32-bit BMP properly. For reliable transparency, consider converting to PNG instead.

When to Use BMP Format

Legacy Software

Older applications and systems that don't support modern formats like WebP, AVIF, or even PNG.

Print Applications

Some older print software and hardware requires uncompressed BMP files for proper output.

Development

Raw pixel data access without compression artifacts. Useful for image processing and analysis.

Game Assets

Some game engines and tools prefer BMP for textures and sprites due to its simplicity.

Frequently Asked Questions

BMP is an uncompressed format that stores every pixel's color value directly, while WebP uses sophisticated compression algorithms. A 1000x1000 pixel image in 24-bit BMP will always be about 3MB (1000x1000x3 bytes), regardless of content. For smaller files, use WebP to JPG or WebP to PNG instead.

With 24-bit BMP, transparent areas are filled with your chosen background color (default: white). With 32-bit BMP, transparency is preserved in the alpha channel, but many programs don't display it correctly. For reliable transparency, we recommend using PNG format instead.

BMP doesn't support animation. When you convert an animated WebP, only the first frame is extracted. For animated content, consider keeping the WebP format or converting to GIF using our GIF tools.

Choose 24-bit for maximum compatibility - it works with virtually all software. Only use 32-bit if you specifically need to preserve transparency and know your target software supports it. Check your WebP for transparency using our WebP Analyzer first.

Each WebP file can be up to 20MB, and you can upload up to 10 files at once. Keep in mind that the resulting BMP files will be significantly larger. For large images, consider using the resize option to reduce dimensions first.

Conversions happen primarily in your browser for privacy. Any files temporarily uploaded to our servers for fallback processing are automatically deleted within 24 hours. We don't keep copies of your images.
