About the ICO source
ICO packages icon frames for Windows applications and browser favicon delivery. It is best suited to Windows application icons and favicon delivery.
Accepted extension: .ico

What this ICO to BMP conversion does
ForgeConvert validates and decodes each ICO source before encoding a genuinely new BMP file. Renaming an extension would leave the original format unchanged; this process rewrites the image data for legacy Windows software and uncompressed bitmap interchange. Embedded metadata is not copied to the result.
ICO versus BMP
| Characteristic | ICO source | BMP result |
|---|---|---|
| Typical use | Windows application icons and favicon delivery | legacy Windows software and uncompressed bitmap interchange |
| Transparency | Supported | Not supported |
| Animation | Not supported | Not supported |
| Multipage | Container supports it | Not supported |
| ForgeConvert output | ForgeConvert selects the largest valid input frame and creates a single PNG-backed ICO frame. | Uncompressed 24-bit BMP output preserves RGB pixels but removes alpha transparency. |
| Compatibility | Recognized for Windows icons and favicons; general image workflows vary. | Supported by legacy Windows software but unsuitable for normal web delivery. |
About the BMP result
BMP is a legacy Windows bitmap format that ForgeConvert handles as bounded 24-bit or 32-bit true-color pixels. Choose it for legacy Windows software and uncompressed bitmap interchange.
Output extension: .bmp
When this conversion is recommended
This route decodes ICO with the verified ico engine before writing BMP through bmp. It is useful for legacy Windows software and uncompressed bitmap interchange; remember that forgeconvert selects the largest valid input frame and creates a single png-backed ico frame. Only uncompressed Windows BMP with a BITMAPINFOHEADER or compatible larger DIB header is accepted. Output is 24-bit and does not preserve transparency.
When to keep the ICO
Keep the original ICO when its role is Windows application icons and favicon delivery, or when BMP's constraint is unsuitable: Input may contain alpha; ForgeConvert produces uncompressed 24-bit BMP output without alpha. ForgeConvert does not claim that a larger or lossless-looking BMP result restores detail absent from the source.
Quality and feature behavior
Lossless output: Uncompressed 24-bit BMP output preserves RGB pixels but removes alpha transparency. The decoded ICO source starts with this constraint: ForgeConvert selects the largest valid input frame and creates a single PNG-backed ICO frame.
- Transparency: BMP output has no alpha channel, so transparent ICO pixels are removed during conversion.
- Animation: ICO is a still-image source, and this route produces one BMP image.
- Multiple pages: The largest valid ICO frame is selected explicitly.
How to create the BMP files
- Select up to twenty single-frame ICO images.
- Run the converter; files carried from the homepage begin automatically.
- Save each BMP result separately or download the batch as a ZIP.
ICO to BMP FAQ
What changes when ICO becomes BMP?
ICO decoding produces pixels that are encoded using BMP's rules. This route decodes ICO with the verified ico engine before writing BMP through bmp. It is useful for legacy Windows software and uncompressed bitmap interchange; remember that forgeconvert selects the largest valid input frame and creates a single png-backed ico frame. Only uncompressed Windows BMP with a BITMAPINFOHEADER or compatible larger DIB header is accepted. Output is 24-bit and does not preserve transparency.
Is BMP a good destination for this ICO file?
It is a strong fit for legacy Windows software and uncompressed bitmap interchange. Compare that purpose with your original need for Windows application icons and favicon delivery.
Does ForgeConvert retain uploaded ICO images?
No. Files for this ICO-to-BMP task are processed temporarily in memory and are not permanently stored.
