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?
The converter generates 16x16, 32x32, 48x48, 64x64, 128x128, and 256x256 pixel versions.
Can I use this for my website?
Yes! Place the .ico file in your root directory as favicon.ico for automatic browser detection.
Should my source image be square?
Yes, square images work best. Non-square images will be scaled to fit, potentially causing distortion.
