How to capture webpages

Chrome can take a full page screenshot without any extension: open DevTools with F12, press Ctrl+Shift+P, type "capture full size screenshot" and press Enter. It works on simple pages. On pages with sticky headers, lazy images or nested scrolling panels it fails, which is when an extension is worth installing.

To screenshot an entire webpage: load the page fully, dismiss any cookie banner or modal, then run a full page capture that scrolls the document and joins the results. If the content sits inside a panel with its own scrollbar, click inside that panel first so the capture targets it rather than the page behind it.

To screenshot a very long webpage, load all of its content first, then capture. Past about 16,384 pixels of height the browser cannot hold the result as a single image, so the capture must split into tiled parts — or you export to PDF instead, which paginates the content at a readable size.

Press Ctrl+P and choose "Save as PDF" to convert a webpage to a document with searchable text. Use a full page capture exported to PDF instead when the document has to match what you actually saw, because printing re-renders the page through its print stylesheet and often changes it substantially.
