Full Page Screenshot - FullSnapper 作成者: Minor Software

FullSnapper takes the whole page in a single frame. It never scrolls the page and never stitches tiles together, so there are no seams, no repeated sticky headers, and no drift halfway down the image.

This works because Firefox can render an entire document in one pass. Chrome has no equivalent, so screenshot extensions there scroll the page and paste the pieces together. In testing, a 4,900 pixel page is captured in under half a second.

What you get

PNG, JPEG or WebP at 1x, 2x, 3x, or whatever your display uses
PDF on A4, Letter or Legal, with margins, and page breaks that avoid cutting through a line of text
The page address and capture time in the PDF footer
Filename templates: {host} {title} {date} {time} {width} {height}
Copy to clipboard, with an optional size cap so Google Docs accepts the paste
Shift-click the button, or press Alt+Shift+V, for the visible area only
Inner scroll boxes unclamped first, so app layouts come out whole
Lazy images woken before the shot
A measurements panel after every capture: height, duration, resolution, and a warning when something looks wrong


Three permissions, and what each one does

activeTab: reads the page you are looking at, and only when you press the button
scripting: measures the page and wakes up lazy images before the shot
storage: remembers your options


No host permissions. No downloads permission. No alarming install prompt.

Privacy

FullSnapper has no server. Nothing is uploaded, nothing is tracked, and no fonts or scripts are loaded from anywhere. Your captures stay on your machine.

Requires Firefox 140 or later. Bug reports and questions: support@minorsoftware.com
