How is this different from Split PDF?

Divide pages cuts each selected page in half (two halves become two pages). Split PDF extracts or separates whole pages into new files.

Will text stay selectable?

Usually yes—this only changes the visible crop of each copy. Very complex PDFs may behave differently in some viewers.

No. pdf-lib runs entirely in your browser.

Divide pages horizontally or vertically. All processing happens in your browser. No uploads, no signup—your files never leave your device.

Your files never leave your device. All processing happens in your browser.

Choose one PDF. Splitting uses crop boxes in your browser—nothing is uploaded.

Enter which pages to split (e.g. 1-5, 8) or leave blank / type “all” for every page. Pick vertical (left/right) or horizontal (top/bottom).

Each divided page becomes two pages in order. Other pages stay as single pages.
