}About Chrome Extension Icons
Chrome extensions require icons in specific sizes to display correctly across the browser interface. Our tool automatically generates all the required sizes from a single source image, saving you time and ensuring your extension looks professional.
Required Icon Sizes
- 128x128: Used during installation and in the Chrome Web Store
- 48x48: Used in the extensions management page (chrome://extensions)
- 32x32: Used in the Windows taskbar and other OS UI elements
- 16x16: Used as the favicon on the extension's pages and in the context menu
Simply upload your logo (we recommend a 512x512 PNG for best results), and we'll generate optimized PNG files for all these sizes instantly.
Frequently Asked Questions
