For Chrome and Firefox extension makers
Browser extension demo video built from your URL
An extension lives in a tiny toolbar button, which makes it genuinely hard to sell. Rendrio reads your site, scripts the value, and animates your screenshots and brand into a short MP4 that shows what the extension does, ready for your Chrome Web Store listing and social posts.

The problem
A toolbar icon is invisible
Your extension does its magic in a popup or on the page, out of sight until installed. Store visitors cannot picture the benefit from an icon and a paragraph, so installs stall at the exact moment interest peaks.
Store listings without video convert poorly
The Chrome Web Store rewards listings that show the tool in action, yet most extensions ship with screenshots only. Standing beside competitors that demonstrate value, a static listing quietly loses the click to add.
Explaining a subtle workflow
Many extensions improve a task the user already does, so the value is contextual and easy to undersell. A still frame cannot show the before and after, and text alone fails to make the time saved feel real.
What a Browser Extension video is for
Chrome Web Store listing
Add a demo to your store page so shoppers watch the extension work before hitting install. A clear 16:9 MP4 answers the what does it do question instantly and lifts your conversion from browse to add.
Landing page and waitlist
Anchor your marketing site or waitlist page with a short demo that shows the popup and the outcome. Visitors grasp the workflow at a glance, which turns curiosity into installs and early email signups.
Launch and growth posts
Share a vertical cut on X and Reddit where extension users gather. A punchy clip showing the aha moment travels further than a screenshot and drives targeted installs from communities that feel the problem you solve.
How to make a great Browser Extension video
Show the popup and result on your site
Rendrio animates the screenshots on your page, so display both the extension popup and the changed page it produces. Capturing the before and after on your site gives the demo the contrast that makes the value obvious.
Keep the hook about the saved click
Extensions win by removing friction, so let the opening scene name the exact tedious step you erase. Pick the explain tone to keep the script concrete about the task rather than drifting into broad productivity claims.
Match the store aspect ratio
Render 16:9 for the Chrome Web Store slot and a 9:16 cut for social. Having both ready means the same demo serves your listing and your launch feed without a second round of work.
Questions
Can Rendrio demo an extension that only runs inside the browser?
Yes, as long as your site shows the extension in action. Rendrio builds from the screenshots, popup images, and copy on your page. It does not run the extension live or record the browser, so include clear before-and-after shots on the URL you paste.
Does it record the browser or my screen?
No. Rendrio does not screen record or use avatars. It creates motion graphics from your existing screenshots, logo, and brand colors in a clean launch-video style. The quality of the demo depends on the screens you feature on your marketing page.
Which aspect ratio should I use for the Chrome Web Store?
Use 16:9 for the store video slot, since it matches the widescreen player. Rendrio also exports 9:16 and 1:1 from the same script, so you can render a vertical cut for social launches without regenerating the whole video.
How much does an extension demo cost?
Preview for free with no card required. A free signup includes three generations and one HD render. If you want more exports, a Single Render costs nine dollars, and the twenty nine dollar Pack bundles five HD renders with all three aspect ratios.
