Smooth captures.

Screenshots and scroll videos of any website, at exactly the size you pick. A free Chrome extension.

Chrome on phones doesn’t run extensions.

It records the sites other tools can’t.

WebGL, custom scrolling, heavy animation. Set a scroll speed, press record, and it comes out smooth.

Any size you need.

Pick a preset or type your own. The page resizes, so a phone-sized capture shows your phone layout.

Four steps,
right next to your page.

LamaCap opens in Chrome’s side panel, so you can click around the site while you capture it.

  1. 1Pick a size

    Choose desktop, phone or a social format. A 9:16 story gets your site’s phone layout.

  2. 2Take over the tab

    Chrome draws the page at that size, however big your window is. Press Cancel and your tab goes back to normal.

  3. 3Capture

    Take a screenshot, or record a video that scrolls by itself at a steady pace. You can keep the page’s sound too.

  4. 4Trim and download

    Cut the start and end, pick a file size, and download an MP4 that works anywhere.

I made this for myself. You can have it too.

Privacy

Nothing you capture leaves your computer. The LamaCap extension has no servers, no accounts, no analytics and no tracking, and it sends nothing to its developer or to anyone else.

What LamaCap handles, on your computer

Where your captures go

Stills go straight to your Downloads folder. A recording stays in the memory of the panel until you download or discard it, and is gone when you close the panel. Files you download are yours; LamaCap has no copy of them.

How LamaCap reaches the page

While you have a size applied to a tab, LamaCap uses Chrome’s debugger on that one tab to render it at your size, take stills, scroll it and read its host name. Chrome shows a bar saying LamaCap “started debugging this browser” for as long as this lasts. Press Cancel on that bar, or release the tab in the panel, and it stops.

Sharing

The extension doesn’t sell, share or transfer any of this. It has no way to: nothing is sent anywhere. The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.

This website

This website has no accounts, analytics or tracking. If you paste a link into the Try it window, our server asks that site whether it can be shown inside another page, and doesn’t save the link. The site then loads in your browser, and its own privacy policy applies. Like any web host, ours may keep short-lived request logs.

Changes

If this ever changes, this page will say so before an update does anything different.
