Frequently Asked Questions

What's the minimum image size?

At least 512×512 pixels is recommended for best results. Smaller images may appear blurry at larger icon sizes.

What format is best?

PNG with transparency works best for favicons. JPG is also acceptable but doesn't support transparency.

Can I generate different formats?

Currently generates PNG only, which is the modern standard for favicons and app icons.

Is my image uploaded?

No. Processing happens locally in your browser using HTML5 Canvas. Your image never leaves your device.
