Convert PNG to ICO for a favicon
Websites and Windows shortcuts use .ico icon files, which hold several sizes of the same picture. Photostar saves an ICO from any image, with every standard size from 16 to 256 pixels in one file.
Photostar is a free online Photoshop alternative that runs in your browser. There is no account to make, and your files stay on your device.

- Open your logo. Use the button above, or drop the PNG or SVG onto Photostar. A square image with a transparent background works best.
- Make it square. If it is not square, use Image → Canvas Size to add space so the width and height match.
- Export as ICO. Choose File → Export As, pick ICO and click Export.
- Add it to your site. Upload favicon.ico to the top folder of your website. Most browsers look for it there.

Questions
How do I convert PNG to ICO?
Open the PNG in Photostar, choose File → Export As, pick ICO and click Export. The .ico holds six sizes from 16 to 256 pixels.
What size should a favicon be?
Start from a square image of at least 256 × 256 pixels. The ICO file then carries the smaller sizes browsers use.
Does the ICO keep transparency?
Yes. Transparent areas of your PNG stay transparent in every size.
