Chrome Web Store Screenshot Size

Everything you need to know about creating screenshots for your Chrome extension listing.

Accepted Dimensions

1280 × 800

Best quality on high-DPI screens. Use this unless you have a specific reason not to.

640 × 400

Half the standard size. Acceptable but will look less sharp on Retina/HiDPI displays.

Format	PNG or JPEG
Max file count	5 screenshots per language
Aspect ratio	16:10 (both sizes)
Max file size	No official cap, but keep under 1 MB for fast loading
Color space	sRGB recommended

Lead with the most compelling screenshot — it appears first in search results and on the listing page.
Show the extension in action, not just a settings page or logo splash.
Add concise captions or annotations to highlight key features.
Use consistent branding (colors, fonts) across all screenshots.
Avoid excessive whitespace — fill the canvas with useful information.
Test how screenshots look at thumbnail size, since many users see them small first.

Using the wrong aspect ratio — the store will reject anything that is not exactly 16:10.
Low-resolution screenshots that look blurry on modern displays.
Including browser chrome (address bar, tabs) which wastes space and dates quickly.
Text too small to read, especially when the screenshot is shown as a thumbnail.

Yes. You can upload up to 5 screenshots per locale, and each set can use either 1280×800 or 640×400 independently.

Not directly, but compelling screenshots increase click-through and install rates, which do influence ranking.

PNG for screenshots with text and sharp edges (most common). JPEG for photo-heavy screenshots where file size matters.

Yes. You can update screenshots at any time through the developer dashboard. Changes are reflected after review.
