Tips & Best Practices
- 💡Use a square image for best results. Non-square images will be stretched to fit, which may look distorted at small sizes.
- 💡Keep your favicon design simple — fine details disappear at 16x16 pixels. Bold shapes and high contrast work best.
- 💡SVG inputs produce the sharpest results since they can be rasterized at any resolution without quality loss.
- 💡Check the 16x16 preview carefully — this is the size shown in browser tabs and should be clearly recognizable.
- 💡If your source image has transparency, use PNG, SVG, or WebP format. JPG inputs will have a white background.
How It Works
Favicons are generated using the HTML5 Canvas API with high-quality image smoothing. Each size is rendered independently for optimal quality. The ICO file embeds PNG data directly (supported since IE9 / Windows Vista), keeping file sizes small while maintaining full color depth and transparency. The ZIP file is created client-side using the fflate library.
