How to use WebP to BMP

  1. Drop your images onto the page, or click to pick them from your device
  2. Use the default settings, or adjust the options for your file type and target result
  3. Download the finished images one by one, or save the full batch as a ZIP

What WebP to BMP is for

Use this tool when an old app or device needs an uncompressed bitmap from a WebP image. It decodes the WebP and writes a standard 24-bit BMP on your device, placing transparent areas on white.

  • Create a standard 24-bit BMP from a WebP image.
  • Give an old app or device the uncompressed bitmap it needs.
  • Convert modern WebP files into legacy-friendly BMPs locally.
  • Batch-convert WebP images to BMP in one pass.
Privacy note: This tool runs locally in your browser. Your selected image files are not uploaded to CompressImage.ca. Read more on our promise page.

Best practices for better results

Image optimization works best when you choose the right balance between file size, visual quality, dimensions, format compatibility and privacy. These tips help you get a cleaner result.

  • Only create a BMP when a specific app or device needs an uncompressed bitmap.
  • Transparent areas are placed on white, so confirm that works for your image.
  • Expect a much larger file than the WebP; that is how raw bitmaps work.
  • For everyday use, the smaller WebP is the better file to keep.

What happens to your images?

When you choose a file, your browser reads it locally and creates the processed version on your own device. CompressImage.ca does not receive the original image or the finished file.

That local-first approach is useful for personal photos, client work, screenshots, documents, product images and other files you do not want to upload to a third-party server.

When to use another tool

The best tool depends on what you are trying to fix. Compression reduces file size, resizing changes dimensions, conversion changes format, cropping changes framing, and metadata removal cleans hidden information from the file.

WebP to BMP FAQ

What kind of BMP does this create?

A standard 24-bit, uncompressed BMP that opens in any Windows app or legacy program expecting a raw bitmap.

What happens to WebP transparency?

BMP does not support transparency in practice, so transparent areas are placed on a white background during conversion.

Will the BMP be much larger?

Yes. BMP is uncompressed, so it is normally many times larger than the WebP. That size is simply how raw bitmaps work.

Is my image uploaded?

No. The WebP is decoded and the BMP is written entirely in your browser, so nothing is sent to a server.
