Why convert ICO to BMP?
ICO is lossless (icons and favicons that need the ICO container). BMP is lossless (Windows-centric legacy interchange). Converting ICO to BMP remaps pixels into the target container in your browser. Transparency from ICO will be flattened because BMP has no alpha channel.
What changes in the file
- Both formats are lossless; pixels stay bit-stable aside from color-space handling
- Alpha from ICO is flattened onto an opaque background
- You can resize, adjust quality where relevant, and strip EXIF on export
- Conversion runs on this device — the file is not uploaded
How to convert ICO to BMP
- Drop one or more ICO files onto the converter (or pick them from disk).
- Confirm the output is set to BMP, then adjust quality, size, or metadata if needed.
- Download the converted BMP file — processing never left your browser.
About ICO
ICO is the Windows icon container format. It can hold one or more raster images at different sizes and is still used for favicons and desktop shortcuts.
About BMP
BMP is an uncompressed Windows bitmap format. It is simple and widely readable on Windows, but files are large compared with modern compressed formats.
Common questions
Is this ICO to BMP converter free?
Yes. Formatly converts ICO to BMP in the browser at no charge and without an account.
Do you upload my ICO files?
No. Decoding and encoding run locally with browser APIs and WebAssembly codecs when needed. Files stay on this device.
Will converting ICO to BMP reduce quality?
BMP is lossless, so the export keeps the decoded pixels. If the source was already lossy (ICO), prior compression artifacts remain.
