What to expect
- Supported inputs
- PNG images, and any other picture: JPG, WebP, HEIC, AVIF, SVG, BMP, or GIF.
- What happens
- The picture is scaled down to each size and stored as a PNG inside the ICO, with transparency kept. A picture that isn't square sits in the middle of a transparent square. Sizes bigger than the picture are left out, so it's never blown up.
- Limits
- ICO holds up to 256 × 256 pixels. Start from a square picture at least 256 pixels wide for the sharpest icon.
