What to expect
- Supported inputs
- JPG and JPEG images, and any other picture: PNG, WebP, HEIC, AVIF, SVG, BMP, or GIF.
- What happens
- The picture is scaled down to each size and stored inside the ICO. A picture that isn't square sits in the middle of a transparent square. Sizes bigger than the picture are left out.
- Limits
- ICO holds up to 256 × 256 pixels. A JPG has no transparency, so its background stays; start from a PNG with a transparent background for an icon without a box around it.
