How it Works

1. URL Input and Processing

When you enter a URL, the tool first prepares it by:

  • Trimming any leading/trailing whitespace
  • Ensuring the URL starts with 'http://' or 'https://'
  • Extracting the base URL (e.g., 'https://example.com')

2. Favicon Location Strategies

The tool employs a multi-step strategy to find the favicon:

Standard Paths

It first checks common locations:

  • /favicon.ico
  • /apple-touch-icon.png
  • /apple-touch-icon-precomposed.png
If found, the URL is immediately used.

3. Client-Side Image Checks

For each potential favicon URL (both standard paths and those found in link tags):

  • An Image object is created in JavaScript.
  • The src attribute is set to the favicon URL.
  • onload and onerror events are used to determine if the image exists and is accessible.
  • This is done entirely client-side, avoiding unnecessary server requests.

4. Download Functionality

The download feature works differently for ICO and other formats:

  • ICO: Direct download by creating an a tag linking to the favicon.ico URL.
  • PNG/JPG: If the favicon isn't already a PNG or JPG, a canvas element is used to convert the image, then download it. This ensures cross-origin compatibility and the correct format.
