BMP to ICO Favicon Converter
Convert a BMP image into a downloadable 32×32 ICO favicon.
Making an ICO favicon from BMP
ICO files are used for browser favicons and many Windows-style icons. BMP images often store large uncompressed pixel arrays, so converting them can reduce download or storage size.
Choose an icon size appropriate to your target application. Small icons lose fine detail when scaled down, so simple, high-contrast artwork often works better than detailed photographs.
Before you download
- Inspect the icon at its final small display size before deploying it to a website.
Instructions
- 1

The favicon is scaled to 32×32 pixels and may lose detail.
Practical questions
What changes between BMP and ICO?
The tool decodes a BMP image and encodes its pixels into a new ICO file. Changing the extension alone would not perform this conversion. The browser must successfully decode the source format before the export can run.
What should I check before using the result?
This tool produces a small icon, typically 32 × 32 pixels. Fine detail and thin lettering may disappear when reduced to favicon size.
