_Updated July 2026 · Arthize · https://arthize.com/for/engineers/split-by-bookmark_

Arthize lets engineering teams split a PDF by bookmarks in a private workspace — free, with no watermark. Splitting by bookmark divides a document at its chapter or section markers, producing one file per bookmarked section automatically.

## Why engineers split a PDF by bookmarks

An engineer merges drawings and specs into one submittal, compares two revisions to catch changes, and archives the final set as PDF/A so it stays readable for the project's lifetime.

**Built for drawings.** Whether it's drawings, specifications, reports, Arthize's split pdf by bookmark keeps the work inside your private workspace. Project documents can be commercially sensitive; a private workspace protects designs and client data.

## What matters when you split a PDF by bookmarks

Splitting by bookmark uses the document's own structure to define the cuts.

It saves counting page ranges for chaptered documents.

Each section becomes its own file.
