Chrome Extension Toolbar Icon Previewer

Create perfect toolbar icons for Chrome extensions with instant preview and customization tools.

Chrome Extension Toolbar Icon Previewer helps extension developers test how their icons will look in the Chrome toolbar before publishing. Upload your own 32×32 icon or use our auto-resize feature to see exactly how your extension will appear to users. With customizable borders, real-time previews, and easy drag-and-drop functionality, perfecting your extension's visual presence has never been easier. Stop guessing how your icon will look—see it live in Chrome's toolbar and make adjustments instantly.

➤ How it works Simply upload your icon through our intuitive interface. The extension instantly displays your icon in a realistic Chrome toolbar preview, allowing you to see exactly how it will appear to users. Toggle borders on or off, change border colors, and reset to default with a single click.

➤ Go beyond basic icons Chrome Extension Toolbar Icon Previewer goes far beyond manual testing methods. Instead of repeatedly building and loading your extension to check icon appearance, instantly preview changes in real-time. Our border customization tools help you ensure your icon stands out clearly against any background, and the auto-resize feature automatically converts non-standard dimensions to the required 32×32 format.

For developers: The preview accurately simulates Chrome's toolbar environment, showing you exactly how your icon will appear alongside other extensions. This saves valuable development time and helps you perfect your extension's visual branding before release.
