Limits

Links are not kept. The text in the PDF is real text, but a hyperlink in the page is not a link in the file.

A video is always a still. Settings decide whether that is the frame it paused on or an empty area.

Text drawn into a canvas is a picture. Some maps, charts and document viewers paint their text into a <canvas>, where it is not text to the browser either.

A wide page on A4 or Letter is scaled down, so a 1920 px layout has small body text on paper. The export sheet shows the resulting size in points before you commit, and a single long page does not scale at all.

Chrome's debugging bar shows during every scan. It is Chrome's notice, not the extension's, and it cannot be hidden.

Only http, https and file pages can be scanned. Chrome keeps every extension out of the rest.

DevTools open on the tab forces the raster fallback, whose PDF holds an image rather than text. Only one debugger can attach to a tab at a time.

An app that scrolls inside a box, as Gmail does with its message list, is captured in full by the vector capture. The raster fallback scrolls the window only, so it gets one screenful of such a page.

A page past 60,000 CSS pixels on a side is captured up to that point, and the editor and the export sheet say how much is missing. The limit exists because an endlessly scrolling page has no bottom.

A full-screen hero can occasionally come out taller than it looks. Before laying the page out, the extension pins anything sized to the screen at its on-screen height. It cannot override a height the page sets inline with !important, or read a stylesheet served from another domain.

Captures are temporary. One is deleted the next time the extension starts if it is more than 12 hours old. That happens at startup rather than on a timer, so a browser left open keeps it longer. Export what you want to keep.
