Why Full-Page Screenshots Break (Sticky Headers, Parallax, Blank Sections) and How to Fix Them

You take a full-page screenshot of a beautiful site and get back a mess: the header repeated six times, a section missing, a strange gap halfway down. It's not you. Modern websites are built for scrolling, and most capture tools aren't. Here's what's going on.

First, how full-page screenshots are made

There are two approaches, and each has its own failure modes:

• Scroll and stitch: the tool scrolls the page one screen at a time, captures each screen, and glues them together. Most extensions work this way.
• Render tall: the tool pretends the window is as tall as the whole page and captures it in one shot. Chrome's DevTools command works this way.

Problem 1: the header repeats down the page

Cause: a sticky or fixed header stays at the top of the screen while you scroll. A scroll-and-stitch tool captures it on every screen, so it appears in every slice.

Manual fix: after the first screen, hide the header with your browser's inspector (right-click it, choose Inspect, and set it to display: none), then capture. Fiddly, and you have to do it for every site.

Problem 2: blank or half-faded sections

Cause: many sites fade or slide content in when it scrolls into view. A render-tall tool never scrolls, so that content never gets triggered and stays invisible. A scroll-and-stitch tool may catch it halfway through the animation.

Manual fix: scroll slowly to the bottom of the page and back to the top before capturing, so everything has animated in.

Problem 3: gaps and jumps from parallax

Cause: parallax backgrounds move at a different speed from the rest of the page. When slices are stitched together, the background doesn't line up, leaving seams, repeated strips or gaps.

Manual fix: there isn't a good one. You can try turning off animations in your operating system's accessibility settings (many sites respect "reduce motion"), but plenty of sites ignore it.

Problem 4: missing images

Cause: to load faster, sites often wait to load images until you scroll near them. If the capture happens before they load, you get empty boxes.

Manual fix: scroll through the whole page first and wait a moment for images to load.

Problem 5: a giant stretched hero

Cause: heroes are often set to "100% of the screen height". When a render-tall tool pretends the screen is thousands of pixels tall, the hero grows to match.

Manual fix: use a scroll-and-stitch tool instead for that site.

Problem 6: cookie banners and chat bubbles everywhere

Cause: they're fixed to the screen, so like sticky headers they can appear in every slice.

Manual fix: accept or dismiss the cookie banner and close any chat widgets before you capture.

The one-click fix

We built Pretty Sites because we kept hitting every one of these. When you click Snap full page, it prepares the page first:

• It glides through the page once so lazy images load and scroll animations finish.
• It shows sticky and fixed elements once, then hides them for the rest of the capture.
• It holds parallax, sliders, marquees and playing videos still while it captures.
• It captures at your real screen size, so heroes stay the right height.

Then you get one clean image as a PNG or JPG, or copied to your clipboard. Full-page screenshots are free and unlimited. Add it to Chrome.

You'll still want to close cookie banners yourself first, since only you can choose accept or decline.
