How to split a long screenshot into pages
A 9,000-pixel-tall image is fine on screen and useless on paper. Cutting it into page-sized slices is the whole point of a scrolling capture.
Even: same height every time
The simplest rule. Pick a slice height and the image is cut at that interval. Use it when the content has no structure to respect — a long chart, a photo, a table with uniform rows.
The slice height comes from the page preset, but you can type an exact number instead of dragging the slider. On a very tall capture one pixel of slider travel can be dozens of pixels of image, so the number box is the only way to nudge a cut a little.
Auto: cut where the page is empty
Automatic splitting scans the image and looks for rows that are blank, then prefers those over the arbitrary height. It considers heading and paragraph boundaries reported by the page, and rows that are uniform in colour across the content column.
It also handles a case that trips up most tools: a capture of a document viewer, where pages are separated by a grey gutter. Those gutters are the correct cut points, and the gutter itself gets trimmed away rather than split in half, so no slice starts with a grey band.
What auto cannot do is understand meaning. It does not know that a heading belongs with the paragraph under it, or that a table should not be broken at all. Expect it to get most cuts right and two or three wrong.
Manual: finish it by hand
Manual mode starts from whatever the even or automatic pass produced, so you are correcting a draft rather than starting from an empty preview.
- Click anywhere on the preview to place a split line.
- Drag a line to move it. It snaps to nearby blank rows and structural boundaries.
- Press the × on a line to remove it.
- Ctrl+Z undoes, Ctrl+Shift+Z redoes — split lines and annotations both.
Exporting the slices
Once the lines are where you want them: Split PDF writes one PDF page per slice, Split images writes a ZIP with one file per slice. There is a setting for whether a short last page is trimmed to its content or padded out to the full page size — trimmed looks better on screen, padded is right if the pages will be printed.
