OpenCapture › Guides
Four jobs that look like one job. Getting a web page out of the browser and into a file you can keep, send or print sounds simple until the output arrives with the colours missing, the images blank, or a table cut in half by a page break. These guides cover what each browser can already do, where it stops, and what to do then.
Every one of these guides leads with the built-in method, because it is free, it is already installed, and for a short page it is often enough. An extension earns its place at a specific point — long pages, editing before you send, or an output format the browser will not produce — and each guide says where that point is rather than assuming you are past it.
Two different things people mean by this, and they produce different files. Covers the built-in print-to-PDF route, the four ways it goes wrong on long pages, and when capturing the page as one image is the better answer.
Edge has the best built-in, Firefox is two clicks, and Chrome has nothing in its menus at all. What each browser can do without an extension, and the one preparation step that fixes most bad captures.
Firefox ships a real full-page capture tool, no extension needed. How to reach it, and the three limits you will hit: PNG only, no editing, and a canvas ceiling that silently truncates long pages.
If the output has to be a document — something to attach, file or archive — start with the PDF guide, which explains the trade-off between selectable text and a file that looks like the page. If it just has to be looked at, a single image is the least fragile container, and the scrolling screenshot guide covers it.
If you are on Firefox specifically, start there: it is the only browser with a proper full-page capture built in, and it is worth knowing what it can do before installing anything.
All four guides describe the same product where it comes up: OpenCapture captures a full page, lets you crop, annotate and blur before exporting, and produces PNG or PDF. It is free, needs no account, runs on your device, and the source is public. Where a browser’s built-in tool does the job, the guides say so.
