Frequently Asked Questions
We support PNG, JPEG, and WebP formats. For best results, use a square image with transparent background. The final icons will always be exported as PNG files to meet Chrome Web Store requirements.
Chrome extensions require a 128×128 pixel icon with the actual artwork being 96×96 pixels (16-pixel transparent padding). The icon must work on both light and dark backgrounds and should be front-facing without dramatic perspective angles. For complete technical specifications, see the official Chrome extension icons documentation.
Our tool generates all required Chrome extension icon sizes: 16×16 (toolbar), 32×32 (address bar), 48×48 (extensions management), and 128×128 (Web Store listing). Each size is optimized for its specific use case.
Ensure your original image is high quality and at least 128×128 pixels. Simple, bold designs work best for small icons. If details are lost at 16px, consider simplifying your design or using a more geometric approach.
Currently, we don't offer in-browser image editing. We recommend using an editor like GIMP, Photoshop, or Canva to prepare your image before uploading. Make sure it's square and has good contrast.
Yes! This tool runs entirely in your browser using client-side JavaScript. Your images are processed locally on your device and never uploaded to our servers. The icons are generated instantly in your browser memory and downloaded directly to your computer.
After downloading, place the icon files in an "icons" folder within your extension directory. Then copy the provided manifest.json code snippet into your manifest file to declare the icon paths.
The Chrome Web Store applies automatic formatting to icons. Make sure your 128×128 icon has proper transparent padding and works on both light and dark backgrounds. Avoid adding your own borders or frames.
