Best Practices for SVG to ICO Conversion

• Use Square Aspect Ratios: Icons work best with 1:1 aspect ratio. Make sure your SVG is square (e.g., 512x512) before converting.
• Keep It Simple: Icons should be recognizable at small sizes. Avoid overly complex designs with fine details.
• Test Multiple Sizes: Always check your icon at 16x16, 32x32, and 48x48 to ensure clarity at all sizes.
• Maintain Transparency: If your SVG has a transparent background, make sure it's preserved in the ICO file.
• Generate Multiple Resolutions: Create ICO files with multiple embedded sizes (16x16, 32x32, 48x48, 256x256) for best compatibility.
