What this tool does

The tool reads top-level outline destinations, resolves each destination page, and copies the page interval up to the next bookmark.

Section range = bookmark start page through the page before the next distinct bookmark destination.

The PDF must contain resolvable bookmarks. Nested bookmarks are grouped under their top-level parent in this browser version.

Supported formats

Input must be a valid PDF readable by the browser libraries. Processing capacity depends on page complexity and available device memory.

FAQ

Does split pdf by bookmarks upload my documents?

No. The selected files are read and processed by JavaScript in your browser. The page does not send the PDF contents to a processing server.

Can split pdf by bookmarks process password-protected PDFs?

No. Remove the password with the document owner's permission before using this tool. Encrypted or damaged files may be rejected by the PDF libraries.

Why does my PDF show no usable bookmarks?

Some PDFs only display a visual table of contents and contain no outline destinations. This splitter requires actual PDF bookmarks that resolve to pages.

Why can a large PDF fail in the browser?

PDF processing uses device memory. Very long documents, complex vector pages, and high-resolution visual comparisons can exceed the memory available to the browser tab.

Which browsers work best for split pdf by bookmarks?

A current desktop version of Chrome, Edge, Firefox, or Safari is recommended. Keep the tab open until the output download becomes available.
