About the BMP to ICO Converter
Need to turn a BMP file into ICO? This free converter changes BMP images into ICO in a few seconds, right in your browser. People usually convert because BMP files are huge and cannot be used on most websites, while ICO gives you a multi-size favicon.ico. ICO files open in Windows Explorer, every browser (as a favicon), Visual Studio and icon editors.
The converter decodes your BMP with your browser's own image engine and writes the ICO with a small open-source ICO encoder, so quality settings are applied precisely. Because everything happens on your own device, your images are never uploaded, stored or seen by anyone else, which makes it safe for ID photos, Aadhaar or PAN scans and personal pictures.
What to expect: ICO stores the pixels without further quality loss; camera metadata such as GPS location is removed because the image is re-encoded.
How to use the BMP to ICO Converter
- Click "Choose files" or drag your BMP images onto the box. You can add several at once.
- Optionally set a background colour; all standard icon sizes are generated automatically.
- Press "Convert to ICO". The conversion runs on your device and shows its progress.
- Download each ICO file, or use "Download all (ZIP)" when you converted several.
- Open the result in Windows Explorer or every browser (as a favicon) to check it; your original BMP is never changed.
Tips & benchmarks
- Start from a square image of at least 256×256 px; the converter packs 16, 32, 48, 64, 128 and 256 px sizes into one ICO.
- For a website favicon, upload the ICO to your site root as /favicon.ico and add a 180×180 PNG apple-touch-icon as well.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the ICO to a website or government portal.

What is a BMP file?
BMP is the classic Windows bitmap format. It stores raw pixel data with little or no compression, so files are large, but almost every old program, embedded device and industrial machine can read it.
What is a ICO file?
ICO is the Windows icon format, and it is still the standard favicon.ico that browsers request for every website. One ICO file can hold several sizes, such as 16, 32 and 48 pixels, so the icon looks crisp everywhere.
