About this tool
Upload a PNG image, pick the icon sizes you need, and a proper multi-resolution .ico file is assembled right in your browser.
Frequently asked questions
- What's the file size limit?
- 8MB for the source PNG.
- What sizes are included in the ICO?
- Whichever of the 7 standard Windows icon sizes (16×16 through 256×256) you select — the exported .ico packs every selected size into one file, so Windows can pick the right one for each context.
- What happens if my image isn't square?
- Pad letterboxes the image onto a transparent square background, keeping its full content visible. Crop scales the image up and trims the edges to fill the square exactly.
- Is my image uploaded anywhere?
- No. The conversion runs entirely in your browser using the Canvas API — the file never leaves your device.
