The PDF corner

Split a PDF or pull pages out of it

Type “1-3, 7, 12-” the way you normally type it. The tool shows you the exact list of pages it is about to take BEFORE it acts, and names the ones you asked for that do not exist.

This file is beyond what this tool does

This tool needs JavaScript to work, and that is precisely because it works ON YOUR DEVICE: without JavaScript, your file would have to be sent to a server. The instructions and the limits of the tool, however, can be read without JavaScript, just below.

How this is built

Your file never leaves your device

This tool works entirely inside your browser. Not one byte of your file is sent anywhere, and nothing is kept once the tab is closed.

Checkable in ten seconds, without taking our word for it:

Open your browser's inspector: the F12 key (or Ctrl+Shift+I, or Cmd+Option+I on a Mac).
Go to the “Network” tab, then clear the list.
Process a file on this page. The list stays empty: no request goes out.
To go further: cut your connection and do it again. The tool still works.

This absence of requests is also checked BY MACHINE before every release: a lock drives a real browser, processes a real file, and refuses to publish if a single byte goes out.

InstructionsHow it works

PDFs only. The range counts pages of the document, not the numbers printed on the pages: if your document starts with two cover pages, the page “1” in the footer is page 3 of the file.
