Frequently Asked Questions
Will my PNG transparency be preserved in the ICO file?
Yes. ICO format supports transparency, and our converter preserves the alpha channel from your source PNG image. Your favicon will have a proper transparent background.
What PNG size works best for favicon conversion?
A square PNG of at least 32x32 pixels works well. If your source image is larger, our converter will automatically resize it to 32x32. For best results, start with a 64x64 or 128x128 square image.
Can I create multiple sizes in one ICO file?
Our converter generates a standard 32x32 ICO file, which is the most commonly used favicon size. For multi-size ICO files, you may need a specialized icon editor.
