Chrome Theme Asset Cropper
Upload one image and crop it for all required Chrome Web Store asset sizes
How to Crop Chrome Theme Assets
Upload Your Image
Click the upload area or drag and drop any image file. Use a high-resolution image for the best results across all asset sizes.
Adjust Each Crop
Four croppers appear automatically — one for each required Chrome Web Store asset. Drag and resize the crop area to frame the perfect portion of your image for each size.
Download Your Assets
Download each asset individually or click "Download All" to get all four images at once. Each file is saved as a PNG at the exact pixel dimensions required by the Chrome Web Store.

Frequently Asked Questions
Is this Chrome theme asset cropper free?
Yes, completely free. No account, no watermarks, no limits. Use it as many times as you need.
What image sizes does the Chrome Web Store require?
The Chrome Web Store requires four image assets for theme submissions: Icon (128×128 px), Screenshot (1280×800 px), Small Promo Tile (440×280 px), and Marquee Promo Tile (1400×560 px). This tool generates all four from a single image.
Are my images uploaded to a server?
No. All image processing happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device and are never sent to any server.
What image format should I upload?
You can upload any common image format — PNG, JPG, JPEG, or WebP. For the best quality, use a high-resolution PNG or JPG image (at least 1400 pixels wide). All exported assets are saved as PNG files.
Can I use this tool for Chrome extensions too?
Yes! The icon (128×128), screenshot (1280×800), and promo tile sizes are the same for Chrome extensions and themes. This tool works perfectly for both.
