Full Page Screenshot & Webpage to PDF 作者： Apps Publisher

Take a full-page screenshot of any webpage: the whole thing, including everything below what fits on your screen.
Click the toolbar icon or press the keyboard shortcut. The page scrolls itself from top to bottom, each screenful is photographed, and the sections are joined into one continuous image. Your scroll position is put back exactly where it was, and the finished screenshot opens in a new tab. From there you can crop it, draw on it, blur anything private, and save it as a PNG, a JPG or a PDF.

There is no setup, no account and no sign-in.

WORKS ON REAL PAGES

Most pages are not simple, so the capture is built around the things that usually ruin a long screenshot.

Sticky headers and floating navigation bars are captured once, at the top, rather than repeating down the whole image. Images that only load when you scroll to them are given time to arrive first. Animations and transitions are allowed to settle, so nothing is caught mid-fade. Panels that scroll on their own, such as a mail client or a chat window, are captured even when the page behind them does not move. High-density displays are captured at their real pixel density.

When a page is too tall to fit inside a single image, which is a browser limit rather than one of ours, it is split into parts that join edge to edge with nothing missing between them.

SAVING YOUR CAPTURE

PNG keeps every pixel exactly as captured. JPG trades a little quality for a much smaller file, and you choose how much. PDF offers A4, Letter, Legal, or one long page sized to the image itself, in portrait or landscape; page breaks are nudged towards the gaps between lines of text instead of slicing through them.

You can also copy the image straight to the clipboard, and set the pattern used to name saved files.

EDITING

The result page includes crop, pen, line, arrow, rectangle, ellipse, highlight, text and stickers, with undo and redo. There is a blur tool as well, for the practical reason that a screenshot often contains a name or an account number you would rather not share before sending it on.

It is deliberately small. This is a screenshot tool, not an image editor.

PRIVACY

Everything happens on your own computer. There is no server and nothing is uploaded. The extension makes no network requests at all, and its own pages are served with a security policy that blocks outgoing connections at the browser level.

It also asks for no access to websites. Firefox hands it one tab at the moment you press the button, and takes that access back when the capture finishes. No browsing history is read. There is no analytics, no telemetry and no tracking of any kind.

GOOD TO KNOW

Firefox does not let any extension run on about: pages, addons.mozilla.org, or other extensions' pages, so those cannot be captured. Keep the tab in view while it works, because the browser can only photograph the tab you are looking at. Content inside a cross-origin frame is captured as it appears on the page.

Built on Manifest V3, open source, with no third-party code in the package.
