Why Convert ICO to BMP Format?

ICO files only work as Windows icons and favicons, but BMP is the native Windows bitmap format that every version of Windows and virtually all desktop software understands. Converting ICO to BMP lets you:

  • Use icon artwork in legacy Windows applications, resource editors, and tools that only accept BMP.
  • Get uncompressed, pixel-exact output - BMP stores every pixel without any compression artifacts.
  • Extract every embedded icon size as a separate BMP file in one pass.
  • Prepare graphics for embedded systems and industrial software that require plain bitmaps.
The converter outputs standard 24-bit BMP files for maximum compatibility - transparent areas are placed on a clean white background. Need transparency kept? Use the ICO to PNG converter. To go the other way, try BMP to ICO.

FAQ - ICO to BMP Converter

Is this ICO to BMP converter free to use?

Yes! This ICO to BMP converter is completely free with no hidden charges, watermarks, or subscription fees. Convert as many files as you need without any cost.

What happens to transparency when converting to BMP?

The converter outputs standard 24-bit BMP files for maximum compatibility, so transparent areas are flattened onto a clean white background. If you need transparency kept, use our ICO to PNG converter instead.

Will I get multiple BMP files from one ICO?

Yes! ICO files typically contain multiple sizes (16x16, 32x32, 48x48, 256x256, etc.). Our converter extracts each size as a separate BMP file, giving you all available resolutions from the original icon.

Why are BMP files larger than other formats?

BMP is an uncompressed format - it stores every pixel directly, which makes files larger but guarantees pixel-exact quality and universal compatibility with Windows software.

Can I convert a website favicon to BMP?

Absolutely! Use the "Convert from URL" feature to paste any favicon URL (usually at domain.com/favicon.ico) and extract all icon sizes as BMP files.

Can I convert multiple ICO files at once?

Yes, batch conversion is supported. Upload up to 20 ICO files simultaneously and convert them all to BMP format in one operation. When you convert more than 2 files, a ZIP archive with a README is created automatically.
