Full screenshot: save an entire web page as a single image
Captura Completa is a free Chrome extension that saves an entire web page as a single image, including all content below the scroll line. It works by scrolling through the page, capturing each screen and merging the screenshots into a single PNG or JPEG file. It requests three permissions (activeTab, scripting and storage), does not declare any host permissions and does not send data to any server: the image is composed within the user’s browser. It is developed by AMDT, a digital marketing consultancy based in Madrid.
Chrome has a limitation you may have encountered at some point: it only captures what fits on the screen. If you need the full layout of a page — header, body and footer — you have to take three or four screenshots and assemble them manually in an editor. With any luck, they’ll line up.
Full Capture is a free Chrome extension that solves exactly that problem: it saves the entire page as a single image, however long it may be, without anything leaving your computer.
Cómo funciona
Click the icon. The extension scans the page from top to bottom, takes a screenshot and merges them into a single file. When it’s finished, it shows you the result in a new tab so you can download it or copy it to the clipboard.
That’s it. There’s no need to configure anything, sign up or create an account.
What it solves that others don’t
It’s clear that merging screenshots sounds simple until you try it on real websites. Problems crop up straight away, and they are as follows:
- Fixed headers and menus. The ones that follow you as you scroll would appear repeated on every screen. The extension removes them after the first screenshot, as well as trust badges and chat windows that float over the content.
- Lazy-loaded images. Those that only load when you hover over them would leave blank gaps. They are preloaded before you start.
- High-density screens and browser zoom. The scale is calculated automatically based on the screenshot itself, so there are no misalignments between strips.
- Pages that change height whilst being scrolled through. This is more common than it seems: the footer of many websites grows just as it becomes visible. The extension re-measures before finalising the screenshot.
Let me explain 🙂 Each of these points is a scenario that caused the screenshot to break during development. These aren’t textbook hypotheses: they’re bugs that cropped up whilst testing on PrestaShop shops, WordPress and Elementor websites, and Shopify Headless stores.
Privacy: three permissions and no server
This is where this extension stands out from most others in its category. Screenshot tools are a field with quite a few extensions that collect browsing data, so it’s worth checking the permissions before installing any of them.
Full Screenshot requests three permissions, and no more:
- activeTab — access to the active tab only when you click the button. Access expires once the capture is complete.
- scripting — injects, only whilst the screenshot is being taken, the script that measures the page and controls scrolling.
- storage — to remember your preferences, stored on your own device.
Basically: it does not request any host permissions, so it cannot read any websites until you invoke it. There are no servers, no analytics, no telemetry and no user accounts. The image is composed in your browser’s memory and is only saved to your hard drive if you click ‘Download’.

Limitations you should be aware of
We’d rather tell you about them before you discover them yourself:
- It does not work on chrome:// pages, in the Chrome Web Store itself or in the PDF viewer. This is not a shortcoming of the extension: Chrome prohibits it at browser level and no extension can bypass this restriction.
- Internal scrolling within a specific container is not captured; only the document’s scrolling is captured.
- On infinite-scrolling pages, up to 150 screenshots are captured, after which it stops.
- Above a certain size, the image is automatically scaled down, as the browser does not support unlimited canvases. The extension itself will notify you when this happens.

Frequently Asked Questions
How do I take a screenshot of an entire web page in Chrome?
Chrome does not include this feature natively: its built-in screenshot function only captures the visible area. To save the entire page, you need an extension that scans the page and stitches the partial screenshots together. ‘Captura completa’ does this in a single click and saves the result as a PNG or JPEG.
¿Es gratis Captura completa?
Yes, it’s completely free and has no paid version, subscription or locked features. All its options are available from the moment you install it.
What permissions does it request, and are they safe?
It requests three: `activeTab`, which grants access to the tab only when the button is pressed and expires once the process is complete; `scripting`, to inject the script that measures the page during the capture; and `storage`, to save preferences on the user’s device. It does not request any host permissions, so it cannot read any websites until explicitly instructed to do so.
Are the screenshots sent to any server?
No. The image is composed in the browser’s memory and is only saved to the hard drive if the user clicks ‘Download’. The extension does not make any outgoing network requests and does not include analytics or telemetry.
Does it work with fixed headers and scroll-following menus?
Yes. Fixed-position elements are disabled after the first screenshot, so the header appears at the top just once and is not repeated on every screen. The same treatment applies to trust badges and floating chat windows.
On which pages does it not work?
It does not work on chrome:// pages, in the Chrome Web Store or in the built-in PDF viewer. This is a restriction imposed by the browser itself that affects all extensions equally; it is not a limitation specific to this one.
