ICO File Inspector

Parse Windows ICO structure locally and report each embedded image without uploading or executing file content.

ICO file

Choose an ICO fileReads the ICO directory and embedded image headers locally; file contents are not executed.

Before shipping the icons

Create from artwork, inspect tiny sizes, generate platform assets, then audit the local package and manifest declarations before deployment.

Local checks are not deployment checks

These tools do not fetch your live site, verify HTTP headers, confirm browser cache refresh, test service workers, or certify installability across every platform.
