01
Show the feature, not the settings
The first screenshot should show your extension doing the thing people came for, not its options page.

Your screenshot
A raw capture of your extension popup or of your website works fine. The tool never stretches it: the frame follows your image ratio.

Your screenshot stays on your computer. Every image is composed in your browser and the ZIP is built there too. Nothing is sent to a server.
The visuals the Chrome Web Store asks for
Dimensions are checked at upload. A file one pixel off is rejected, which is why this tool composes at the exact size rather than resizing afterwards.
| Visual | Size | Required |
|---|---|---|
| Screenshot | 1280 × 800 or 640 × 400 | Yes, at least one |
| Small promo tile | 440 × 280 | For promoted placements |
| Marquee promo tile | 1400 × 560 | Optional, featured placements |
| Store icon | 128 × 128 | Yes, see our icon generator |
What makes a screenshot convert
Your screenshots are the only thing most visitors look at before installing. A few rules help.
02
One short sentence per image
A title that names the benefit beats a title that names the screen. Keep it readable at thumbnail size.
03
Keep a consistent background
Using the same color across all your screenshots makes the listing look deliberate rather than assembled in a hurry.
FAQ
Quick answers about Chrome Web Store visuals.
What image sizes does the Chrome Web Store require?
Screenshots must be 1280x800 or 640x400. The small promo tile is 440x280 and the marquee promo tile is 1400x560. This tool produces all four at once from a single screenshot.
How many screenshots should I upload?
Google asks for at least one and accepts up to five. One clear screenshot is enough to publish, but several showing different features usually convert better.
Is the promo tile mandatory?
The 440x280 tile is needed for your extension to appear in the promoted sections of the store. The 1400x560 marquee is optional and only used for featured placements.
Can the images have transparency?
No. Chrome Web Store visuals must fill the whole area. Every file this tool produces is an opaque PNG at the exact required dimensions.
Is my screenshot uploaded to a server?
No. Every image is composed in your browser with Canvas and the ZIP is built there too. Your screenshot never leaves your computer.
