Why Convert PNG to ICO?

ICO (Icon) format is the standard for Windows icons and website favicons. Unlike single-size images, ICO files contain multiple resolutions of the same icon, allowing systems to display the best size for each context - from tiny browser tabs to large desktop icons.

Technical Details

ICO files are containers that hold multiple PNG or BMP images at different resolutions. Our converter generates sizes: 16x16 (browser tabs), 32x32 (taskbar), 48x48 (desktop), 64x64, 128x128, and 256x256 (high-DPI displays). All sizes are embedded in a single .ico file.

FAQ

What sizes are included?

Can I use this for my website?
