A multi-resolution icon container used by Windows applications and traditional website favicons. Conversion runs on this device, so your source images never need to leave the browser.
Choose any combination of six PNG-based sizes from 16px to 256px. Non-square artwork is centered on a transparent square; ICO input uses its largest high-depth image.
Choose one or more image. Nothing is uploaded to WebP Cloud.
ICO output will contain transparent 16px, 32px, 48px, 64px, 128px, and 256px PNG images. Non-square sources are centered with transparent padding.
Accepted inputs: JPG, PNG, GIF, BMP, ICO, SVG, TIFF, WebP, AVIF, HEIC, and HEIF. ICO uses its largest high-depth image; TIFF uses the first page; HEIC/HEIF uses the first top-level still image. Metadata is not preserved.
Choose any combination of 16, 32, 48, 64, 128, and 256px images and store them together in one ICO file. All six are selected by default.
Rectangular source artwork is scaled to fit and centered instead of being cropped or stretched.
An ICO can contain several PNG or Windows bitmap images. The converter selects the largest image and prefers the higher color depth when dimensions match.
Other embedded sizes and icon metadata are not preserved during conversion.
Select files or drag them into the converter above.
The browser loads only the codec needed for the input and ICO output.
A single result downloads directly; multiple results are packaged into a ZIP.
