How to Use

1
Select an image: Click the upload area to choose a source image, or drag an image into it. A PNG with a clear subject and clean edges is recommended.
2
Set sizes: Select preset sizes such as 16x16, 32x32, 64x64, 128x128, and 256x256, or enter a custom width and height.
3
Choose a fit mode: For non-square images, use transparent fill, color fill, crop to fill, or stretch to fit. Transparent fill keeps the original aspect ratio.
4

5
Download results: Download a single size, the multi-size ICO file, or a ZIP package with all files.

FAQ

Common image formats such as PNG, JPG, GIF, WEBP, and BMP are supported. PNG images with transparent backgrounds help preserve clean edges for favicons and app icons.

You can use it for website favicon.ico files, software icons, desktop shortcut icons, project resource icons, and other cases that require .ico format.

You can choose transparent fill, color fill, crop to fill, or stretch to fit. Transparent fill centers the full image, while crop to fill makes the icon cover the canvas.

This usually happens when the source aspect ratio differs from the target size, or when transparent fill is selected. Use crop to fill, or crop the source image first, for a fuller icon.

ICO directory entries are commonly handled within 256px. Sizes from 16x16 to 256x256 also cover most favicon and software icon needs.

The tool creates one ICO file containing multiple sizes and also provides separate ICO files for each selected size, so you can download the version you need.
