Add the BMP
Drop, paste, or choose the bitmap needed for a modern ICO workflow. It stays in your browser during conversion.
Free BMP to ICO converter
Convert BMP to amodern ICO icon family.
Fileverses converts a BMP into a PNG-backed ICO in your browser for a modern Windows icon or favicon workflow. It centers the complete decoded image at four sizes, so inspect small results; it does not crop artwork, remove a background, or target bitmap-only legacy ICO readers.

About this converter
Free BMP to ICO conversion, built for a real workflow.
BMP is a raster bitmap commonly associated with Windows workflows, while ICO is an icon container used by Windows and many favicon workflows. This route decodes the BMP in your browser and packages PNG icon entries at 16, 32, 48, and 256 pixels. Each version uses contain scaling to keep the whole image centered in a transparent square rather than cropping it to fill the frame. That is practical for a modern browser, Windows application, or recipient that accepts PNG-backed Vista-era ICO files, but it cannot remove an opaque BMP background, design a legible icon automatically, create every possible icon size, or support a bitmap-only legacy ICO reader. Check the exported icon in its target browser, app, or packaging pipeline before relying on it.
- The ICO has four PNG-backed entries at 16, 32, 48, and 256 pixels. It is a Vista+ style ICO, not a bitmap-only legacy icon file.
- Each entry contain-scales and centers the full decoded image on transparent padding. Nothing is automatically cropped, reframed, or simplified for small sizes.
- PNG-backed ICO entries can preserve decoded alpha, but an opaque BMP remains opaque. This conversion does not erase or replace a background.
- The result is an icon container only. It does not add browser markup, an app manifest, platform-specific packaging, or editable artwork.
How it works
Upload once.
Export ICO.
Keep ICO selected
ICO is preselected for a browser, Windows, or recipient workflow that accepts PNG-backed icon entries.
Convert and test
Download the ICO and test it where it will be used. Check the 16px version, centering, background, and whether the target accepts Vista+ PNG-backed ICO files.
Made for real pipelines

One workspace.
Convert without uploading your assets. Switch outputs anytime — web, print, icons, and document targets from the same batch.

Good to know
Questions, answered.
Which sizes are in this BMP to ICO file?+−
Fileverses packages PNG-backed icon entries at 16, 32, 48, and 256 pixels. It does not generate a separate size for every browser or operating-system convention.
Will this BMP to ICO result work in every old Windows program?+−
Not necessarily. This encoder creates a Vista+ ICO with embedded PNG images. Test the result if the recipient requires a bitmap-only legacy ICO reader or has its own icon-size rules.
Does the converter crop my BMP to make an ICO icon?+−
No. The complete decoded bitmap is scaled to fit and centered in each square, with transparent padding where needed. Fine details or wide artwork may be difficult to read at 16 pixels.
Can BMP to ICO remove a background?+−
No. ICO's PNG entries can keep decoded transparency, but this route does not detect or erase an opaque BMP background. An opaque source stays opaque.
Can I use the ICO as a favicon?+−
It can suit a favicon workflow that accepts this ICO format, but add it to your site's own favicon configuration and test it in the target browsers. Conversion alone does not install or configure a favicon.
Does Fileverses upload BMP files to create ICO icons?+−
No. BMP-to-ICO conversion runs in your browser, so the source bitmap is not sent to a conversion server.
