About WEBP to ICO
Convert a WebP image into a standard ICO container directly in your browser. The tool decodes the WebP, renders separate square frames at the selected dimensions and packages them as PNG-compressed images inside one .ico file.
When WebP to ICO is useful
WebP assets are common in websites, downloaded media libraries and modern design exports, while Windows shortcuts and desktop applications often expect ICO. This focused converter avoids an intermediate manual WebP-to-PNG step. It is designed for static logos, app marks and interface graphics rather than animation.
Select Windows or favicon sizes
The Windows preset offers 16, 24, 32, 48, 64, 128 and 256 pixel frames. Browser favicon shows only 16, 32 and 48 pixels, while Large icons shows 64, 128 and 256 pixels. Click the preview cards to keep multiple sizes selected or exclude frames you do not need. The visible previews are rendered independently at their labelled dimensions.
Use the main button to combine selected frames into one ICO. If a target program asks for one exact dimension, use the download icon on that preview card to create a single-size ICO instead.
Transparency and square fitting
Transparent WebP input can retain its alpha channel in the exported ICO. Keep the whole image scales the complete source into a square canvas and uses transparent padding when necessary. Fill the icon square crops overflow so the artwork reaches the edges. Small icons lose detail quickly, so inspect the 16- and 32-pixel previews rather than judging only the large frame.
The optional solid-background removal works from connected image edges. It can help with a simple flat background, but it is not intended to cut out detailed photographs or gradients.
How to convert WebP to ICO
- Add a static WebP file.
- Pick the Windows, favicon or large-icon preset.
- Click individual preview cards to choose the output sizes.
- Select fit or crop and inspect the true-size previews.
- Build the combined ICO or download an individual size.
Browser processing and compatibility
Supported processing stays on your device; the source is not uploaded during the normal conversion workflow. Current browsers generally decode static WebP reliably, but damaged files or uncommon variants may fail. The ICO output uses modern PNG-compressed 32-bit frames. Test it in the destination program, especially when working with older Windows software that may require legacy bitmap frames.
