About the ICO to BMP Converter
This ICO to BMP converter turns icons from ICO into BMP without installing software or uploading anything. It solves a common problem: ICO files only open in a handful of programs. Converting to BMP gives you a raw bitmap for legacy software, ideal for legacy Windows software, embedded displays, machine vision and printing tools that need raw pixels.
The converter decodes your ICO with your browser's own image engine and writes the BMP with a small open-source BMP encoder, so quality settings are applied precisely. Because everything happens on your own device, your icons 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: BMP cannot store transparency, so transparent areas are filled with a background colour you pick (white by default); BMP 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 ICO to BMP Converter
- Click "Choose files" or drag your ICO icons onto the box. You can add several at once.
- Pick the background colour for transparent areas and, if you like, a maximum width.
- Press "Convert to BMP". The conversion runs on your device and shows its progress.
- Download each BMP file, or use "Download all (ZIP)" when you converted several.
- Open the result in Windows Paint or Windows Photos to check it; your original ICO is never changed.
Tips & benchmarks
- BMP files are uncompressed and large (a 12 MP photo is about 36 MB); transparent areas are flattened onto white.
- Password-protected (encrypted) archives cannot be converted; extract them with the password first.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the BMP to a website or government portal.

ICO (Windows Icon) is a multi-size icon file best suited to website favicons, Windows shortcuts, desktop apps and folder icons. BMP (Windows Bitmap) is a uncompressed raster image best suited to legacy Windows software, embedded displays, machine vision and printing tools that need raw pixels.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.

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.
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.
