How to use this preview
- Upload your logo (or a generated icon like favicon-512.png).
- Check the 16×16 and 32×32 pixel previews — these are the most important for browser tabs.
- If it looks muddy, simplify the icon and regenerate a full pack.

Frequently Asked Questions
Do you upload my image?
No. Previews are rendered locally in your browser.
What should I upload?
Upload your logo, or your generated favicon PNG (like favicon-512.png). Square images work best.
Why does 16×16 look bad?
Most icons need a simplified small-size version. Try thicker shapes, higher contrast, and fewer details.
Need a full pack?
Generate a complete favicon ZIP, then validate it before you deploy.
