Collator

Collator is a fast, one-screen PDF page organizer for your Mac. Drop in a document, see every page as a thumbnail, and fix it in seconds — reorder by dragging, delete the pages you don't need, rotate anything that's sideways, duplicate a page, or split out just the pages you want into a brand-new file.

Everything happens locally. There's no upload, no account, and no cloud round-trip — your documents never leave your Mac.

Collator is built for the PDF chores that come up every day: prepping a scanned form before you send it, pulling a few pages out of a long report, fixing a page a scanner rotated sideways, or combining a cover letter with a resume. One clean screen, real keyboard shortcuts, instant undo — no bloated toolbars, no subscription nag screens.
