About Divide Pages

Cuts every page in half, or into quarters. The case it exists for is a scanned book: two facing pages land on one sheet, and every reader then shows you a spread at half the size it should be. Dividing down the middle turns each spread back into two pages.

Each half is a full page with the source drawn at an offset, so the other half falls outside the sheet and the reader clips it. Nothing is rendered and nothing is re-encoded — a divided page of text is still text, and a divided vector drawing is still vector.

The other common use is a sheet printed four-up that needs to become four pages again: choose quarters, and the pages come out in reading order, left to right and then down.

Where it helps

  • Lossless: the page content is embedded, not rasterised, so text stays selectable.
  • Halves come out in reading order, which is what makes the result usable without reordering.
  • Works on every page of the document in one pass.
  • Quarters as well as halves, for four-up sheets.
  • The document stays in your browser.

Limits

  • The cut is always exactly down the middle — a spread whose gutter is off-centre needs cropping first.
  • Content that straddles the cut line is split between the two pages rather than duplicated.
  • Every page is divided the same way; a document with a mixture needs splitting first.
  • Links and annotations are not carried onto the divided pages.
  • Password-protected files must be unlocked first.

Frequently asked questions

What if my book scan's gutter is not in the middle?

Crop the page first so the spread is centred, then divide. The cut here is exactly half, which is right for a scanner that was aligned and wrong for one that was not.

Does this lose quality?

No. The source page is embedded as page content and drawn at an offset — the same objects, in a smaller frame. Text, fonts and vectors are untouched.

Is the other half really gone?

It is outside the page and clipped by the reader, in the same way a crop hides content rather than deleting it. Rasterise or flatten the result if the hidden half must not travel with the file.

Can I divide only some pages?

Not in one pass — every page is cut. Split the range out first, divide it, and merge it back.
