Icon Checker helps developers, designers, and website owners validate favicons, iOS App Store icons, Google Play listing icons, and Open Graph tags before release.

Upload an app icon or enter a public website URL to check size, format, transparency, crawlability, and other measurable requirements. Every result includes the measured evidence, the expected requirement, an official source, and a clear fix. App icon files are analyzed locally in your browser, with no upload or sign-up required.
