How to Convert WebP to ICO Favicon - Step by Step Guide

Step 1

Upload Your WebP Image

Start by uploading your WebP image. For best favicon results, use a square image (256×256px or 512×512px recommended):

•
Click to upload: Click the upload area or "Upload" button to select your WebP file
•
Drag and drop: Drag your WebP logo or image directly into the upload area
•
Try the sample: Click "Sample" to see demo favicon generation
•
Transparency support: WebP transparency is fully preserved in the ICO file

Recommended WebP Sizes for Favicons

For best quality at all sizes, start with:

→
Optimal: 512×512px square WebP with transparent background
→
Minimum: 256×256px for all standard favicon sizes
→
Modern format: WebP provides smaller file size than PNG
Step 2

Preview Your Image

Once uploaded, you'll see a preview of your favicon source image. The converter will display:

•
Image preview: Visual preview of your WebP image
•
File information: Original file name and size
•
Image dimensions: Width and height verification
Step 3

Automatic Multi-Size Generation

The conversion happens automatically and instantly after upload! Our custom ICO encoder creates a professional multi-resolution favicon using the HTML5 Canvas API:

•
6 standard sizes: 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 pixels
•
High-quality scaling: Uses advanced image smoothing for each size
•
Single file output: All sizes packed into one favicon.ico file
•
32-bit RGBA: Full transparency support preserved from WebP

ICO Size Usage Guide

Each size serves a specific purpose as recommended by MDN Web Docs:

16×16: Browser tabs, bookmarks
32×32: Taskbar, address bar
48×48: Desktop shortcuts
64×64: High-DPI displays
128×128: Chrome Web Store
256×256: Retina displays
Step 4

Download & Use Your Favicon

Once conversion is complete (happens automatically!), you have these options:

•
Download as favicon.ico: Click "Download" to save your multi-size favicon
•
Copy to clipboard: Click "Copy" for quick usage
•
Place in root: Upload favicon.ico to your website's root directory
•
Convert more: Use "Clear" to create another favicon

How to Use Your Favicon

Frequently Asked Questions

What size should my WebP be for best results?

For optimal quality at all favicon sizes, start with a square WebP at least 256×256 pixels. A 512×512px source provides even better quality. WebP's efficient compression means you can use larger source images without worrying about file size.

Does this converter support WebP transparency?

Yes! WebP transparency is fully preserved in the ICO file. The ICO format stores each size as a 32-bit RGBA image, maintaining full alpha channel support for transparent backgrounds.

Why use WebP for creating favicons?

WebP is a modern image format that provides superior compression compared to PNG and JPG. It's perfect for storing high-quality source images before converting to ICO. However, for maximum browser compatibility, ICO remains the recommended favicon format.

Is this favicon generator free?

Yes, absolutely! This WebP to ICO converter is completely free with no watermarks, registration, or file limits. All processing happens in your browser for maximum privacy.

Are WebP favicons supported by browsers?

While modern browsers support WebP images, ICO format is still recommended for favicons to ensure compatibility with older browsers and all platforms. Check WebP browser support and favicon format support for details.

How do I test my favicon?

Upload favicon.ico to your website's root directory and clear your browser cache. Check browser tabs, bookmarks, and history. You can also use online favicon testers or browser developer tools to verify it loads correctly. If you need to extract your favicon later, use our ICO to WebP converter.
