About the Formats
⚡ What is WebP?
WebP is a modern web format by Google (2010) offering excellent compression. It supports transparency and is great for web graphics, but not directly usable as Windows icons.

💡 Pro Tips
- Include 16, 32, and 48px sizes at minimum — they cover most Windows display settings and favicon use.
- For highest quality, start with a square WebP image. ICO works best with square proportions.
- ICO supports 8-bit transparency (256 levels) in 32-bit mode. We preserve full alpha from your WebP.
- If your WebP is animated, only the first frame will be used — ICO is static.
- Browsers request favicon.ico automatically. Place the file in your root directory for instant branding.
- For Retina displays, include 64x64 or 128x128 sizes — they scale better on high-DPI screens.
- You can also convert ICO back to WebP with our ICO to WebP converter for web use.
How WebP to ICO Conversion Works
ICO files are containers holding one or more bitmap images in different resolutions. When you convert WebP to ICO, our servers decode the WebP image, resize it to your chosen dimensions (preserving aspect ratio), and encode each size as a BMP-like image inside the ICO container.
Transparency is handled via an alpha channel in 32-bit icons. If your WebP has transparency, it will be preserved in all generated sizes.
The process is fast and server-side. Files are automatically deleted after 10 minutes.
WebP vs ICO: Different Purposes
WebP is a compression-focused format for web images. ICO is a container format specifically for icons and favicons. While WebP offers better compression, ICO is the only format universally recognized for Windows icons and website favicons.
Converting WebP to ICO bridges the gap: you keep the source in a modern format, but deliver in the required legacy format where needed.
Best Practices for ICO Creation
Always include multiple sizes: 16x16 (small icons), 32x32 (standard), 48x48 (high-DPI), and optionally 64x64, 128x128 for very high resolution. Modern Windows can scale down larger sizes, so including a 256x256 master ensures quality everywhere.
For favicons, 16, 32, and 48 are sufficient. Browsers will pick the best size automatically. Explore our ICO tools for more icon utilities.
