WebP to ICO Converter (Free Online)

Convert WebP images to ICO icon files in your browser. Build multi-resolution favicons and Windows icons from WebP with transparency preserved. Client-side only.

WebP often gives smaller files than PNG with similar quality, and it supports transparency. This tool rasterizes your WebP into square layers and packs them into one ICO file.

How to convert WebP to ICO

  1. Upload your .webp image (drag and drop or browse).
  2. Select icon sizes — start with Recommended, then add 40, 24, or 20 if you need extra Windows shell sizes.
  3. Download your `.ico**. Nothing is uploaded to our servers.

FAQ — WebP to ICO

Does transparency carry over?

Yes. Each layer is generated as PNG inside the ICO, so alpha from your WebP is preserved in those layers.

Why use ICO instead of uploading WebP as a favicon?

Many setups still expect favicon.ico in the site root, and ICO bundles multiple resolutions in one file. You can still use WebP or PNG separately if your stack supports them.

Which browsers support this converter?

Modern browsers that support canvas, WebP decoding, and downloads (Chrome, Firefox, Safari, Edge) can run the tool. Everything runs locally in your browser.
