What sizes should I include in my ICO file?

For website favicons, 16x16 and 32x32 are essential. Adding 48x48 helps with Windows taskbar display, and 256x256 provides high-resolution support. For comprehensive compatibility, include all available sizes.

Can I create a multi-size ICO from a single BMP?

Yes, our converter automatically resizes your BMP image to each selected size and embeds all versions into a single ICO file. This ensures your icon displays correctly at any resolution.

Will my BMP transparency be preserved?

BMP files typically don't support transparency. If you need transparent icons, consider converting a PNG image to ICO instead, which preserves alpha channel transparency.

What's the maximum file size for BMP uploads?

Our tool supports BMP files up to 50MB. However, for favicon creation, smaller source images (under 1MB) are typically sufficient and process faster.

Is this BMP to ICO converter free?

Yes, our BMP to ICO converter is completely free with no hidden costs, watermarks, or usage limits. Convert as many images as you need without registration.

Are my images secure during conversion?

Absolutely. All conversion happens locally in your browser using JavaScript. Your BMP images never leave your device or get uploaded to any server, ensuring complete privacy.
