Why does my full page screenshot have the header repeated?

Sticky headers stay glued to the top of the viewport while the page scrolls, so a naive capture records them in every slice. ScrnCap hides fixed elements after the first slice, which is why the stitched image looks like the page you would get by printing it.

Does it work on infinite-scroll pages?

It captures what has actually loaded. On a feed that keeps appending content, scroll to the point you want to stop first, then capture — otherwise the page keeps growing under the capture.

How long can the image be?

Long, but not unlimited — browsers cap how big a single canvas can be, so a page tens of thousands of pixels tall may hit that ceiling. Export as PDF in that case: it pages the content instead of holding it all in one image.

How to take a full page screenshot in Chrome

Chrome can do it without an extension: open DevTools with F12, press Ctrl+Shift+P, type "screenshot" and choose "Capture full size screenshot". With ScrnCap the same thing is one keystroke — Alt+Shift+F — and the result lands in an editor where you can crop and annotate it before exporting.

Doing it manually in Chrome

1Open the page and press F12 (or Ctrl+Shift+I) to open DevTools.
2Press Ctrl+Shift+P to open the command menu.
3Type "screenshot" and pick "Capture full size screenshot".
4The PNG downloads automatically to your Downloads folder.

Where the manual way falls short

It breaks on the pages you most want to capture: sticky headers repeat down the image, elements with their own scrollbars are cut off, and lazy-loaded images come out blank because the page never actually scrolled.
There is no annotation, no format choice and no PDF — you get a PNG, and everything after that happens in some other app.

Doing it with ScrnCap

1Press Alt+Shift+F on the page you want, or open ScrnCap and choose Full page.
2ScrnCap scrolls the page, hides sticky headers and stitches the pieces into one image.
3Crop or annotate in the editor, then export as PNG, JPG, WEBP or PDF.

Free, offline and no account needed — the capture, the annotation and the export all happen on your own machine.
