Convert PNG, JPG, or WEBP images into multi-size Windows .ico favicons
Convert PNG, JPG, or WEBP into a multi-size Windows icon (.ico). Fully in your browser.
PNG, JPG, or WEBP up to 25 MB
Select a PNG, JPG, or WEBP image up to 25 MB.
Choose which icon sizes to include — 16, 32, 48, and 256 px are preselected.
One multi-size icon file downloads instantly — ready to use as a favicon.
The tool resizes the image on an HTML5 canvas for each selected size, encodes each as PNG, and writes a standard ICO file: the ICONDIR header plus ICONDIRENTRY records pointing at each PNG payload. Browsers and Windows select the best size automatically.
Unlike legacy online converters that transmit entire files to third-party cloud servers, our architecture prevents network bottlenecks, provides near-instant processing, and eliminates cloud wait queues.
Optimize and reduce image file sizes with interactive quality controls, percentage saved calculations, and before/after previews. 100% private in-browser compression.
Convert Apple iOS iPhone HEIC/HEIF camera photos into universally compatible JPG images with zero file uploads and batch processing.
