Chrome Web Store screenshots, answered
How do I create screenshots for my Chrome extension?+
You capture your extension's UI at the exact sizes the Chrome Web Store requires — 1280×800 or 640×400 pixels — and present each one clearly with a short caption. The fastest way is a purpose-built tool: with Markee you paste your Chrome Web Store listing URL, it pulls your real UI, and it exports a complete, correctly-sized kit in minutes instead of building each frame by hand in Figma or Canva.
What are the official Chrome Web Store image sizes?+
The Chrome Web Store needs screenshots at exactly 1280×800 or 640×400 pixels (24-bit PNG with no alpha, or JPEG), a store icon at 128×128, a small promo tile at 440×280, and an optional marquee promo tile at 1400×560. You must supply at least one screenshot and may supply up to five. Markee generates every one of these sizes in a single kit.
How do I make a 1280×800 screenshot without Figma or Canva?+
Use an automated Chrome Web Store screenshot generator instead of a general design tool. Markee takes your listing URL, rebuilds your screenshots around your actual extension UI on styled backgrounds with readable captions, and outputs pre-cropped 1280×800 (and 640×400) images — no canvas setup, grid alignment, or manual export required.
What is Markee?+
Markee is a Chrome Web Store screenshot and asset generator for extension developers. You paste your store listing URL and Markee produces a polished listing kit — screenshots, the small promo tile, and the marquee — sized to Chrome Web Store spec, wrapping your real UI in clean backgrounds and clear feature captions.
Do better screenshots actually increase Chrome extension installs?+
Yes — the Chrome Web Store shows screenshots prominently and users decide within seconds, so clearer, benefit-led screenshots measurably lift install rates. One developer on r/chrome_extensions reported roughly doubling daily installs after replacing raw screen captures with polished, captioned ones.
Is Markee free to try?+
Yes. Every new account gets 10 free credits on signup — enough for a full kit — with no credit card required. After that, Markee offers a one-time 20-credit pack at $4.99 and monthly or yearly Starter and Pro plans.
Does Markee use my real extension UI or generic mockups?+
Markee builds the screenshots around your real UI, not stock placeholders. It reads your live Chrome Web Store listing and existing screenshots, then redesigns them with backgrounds, framing, and captions while keeping your actual interface at the center.
What image formats and dimensions does Markee export?+
Markee exports Chrome Web Store-ready files: 1280×800 screenshots (the recommended size), the 440×280 small promo tile, and the 1400×560 marquee tile, delivered as a downloadable kit. Every asset matches the Web Store's required pixel dimensions so uploads pass validation on the first try.
