A whole page in a single frame.
FullSnapper does not scroll the page and does not stitch tiles together. There are no seams to line up, so nothing repeats and nothing drifts out of alignment halfway down.
Free. Firefox 140 or later. Three permissions.
How
Firefox can render an entire document in one pass and hand it back as a single image. Chrome has no equivalent, so screenshot extensions there scroll the page and paste the pieces together.
A 4,900 pixel page takes 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 - 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
- activeTab
- Read the page you are looking at, and only when you press the button.
- scripting
- Measure the page and wake up lazy images before the shot.
- storage
- Remember your options.
No host permissions and no downloads permission, so the install prompt has nothing alarming in it. FullSnapper makes no network requests. The privacy policy has the details.
Where it stops
Firefox limits how large a single image can be. A page taller than that comes out as numbered parts that line up exactly, and a 124,000 pixel webtoon chapter makes four to eight of them.
Pages that keep loading content as you scroll can only be captured as far as they had loaded. FullSnapper wakes those images first, then reports how far it reached, instead of handing back an image with a blank strip at the bottom.
There is no editor yet. No crop, no blur, no arrows.
