Add, edit, remove bookmarks and navigate your PDF easily. Build the outline a reader shows down the side of the window, nest sections under chapters, and jump straight to any part of the document. No sign-up or login required. No payment required.
Your PDF opens straight into the bookmark workspace.
Leave the title empty and the new bookmark is named for you — rename it below.
Select a bookmark on the right to edit it.
Changes apply as you type — the list on the right updates with you.
Bookmarks can also be dragged into a new order in the list on the right.
A JSON file holding the titles, pages and nesting — the same shape this tool exports.
