How to Convert ICO to PNG

A step-by-step guide to extracting the largest image from an ICO file and downloading it as PNG.

What an ICO file contains

An ICO file can bundle multiple raster images at different sizes and color depths. A favicon might include 16x16, 32x32, 48x48, and 256x256 images in one file.

ico2png.com currently selects the embedded image with the largest pixel dimensions and exports that image as one PNG. It does not export every embedded size.

Convert a file in four steps

  1. 1. Select a file. Drag an ICO file onto the converter or use “Browse Files.” The current limit is 10 MB.
  2. 2. Let the browser decode it. The converter reads the ICO header, finds the largest embedded image, and converts supported bitmap data with browser APIs.
  3. 3. Review the preview. Check the dimensions and transparency of the PNG preview.
  4. 4. Download the PNG. Use “Download PNG” and choose where to save the file.
Open the converter

What happens to the file?

The current converter processes the selected ICO file in your browser and does not send it to our servers. If local decoding fails, the site shows an error instead of uploading the file automatically.

Troubleshooting

The file is rejected

Confirm that the file has an .ico extension, is no larger than 10 MB, and is a valid ICO rather than another image format renamed to .ico.

The exported image is smaller than expected

The source ICO may not contain a larger embedded image. Check the dimensions shown in the preview.

Transparency looks wrong

ICO files can store transparency in different ways. Try a different browser or another conversion tool, and keep the original ICO until you have verified the output.

A valid ICO still fails

The browser converter may not support that encoding. Do not send a sensitive file by email; report the ICO format details and browser version instead.

When another tool may fit better

Use a tool that explicitly supports batch conversion, every embedded size, resizing, or editing when you need those capabilities. Recheck its current upload and retention policy before using sensitive files.
