## Why architects split a PDF by bookmarks

An architect merges plan sheets and schedules into one issue set, compares two drawing revisions for changes, and exports key sheets to images for a client presentation.

**Built for plan sets.** Whether it's plan sets, schedules, specifications, Arthize's split pdf by bookmark keeps the work inside your private workspace. Designs and client plans are proprietary; private processing protects the practice's work.

## What matters when you split a PDF by bookmarks

Each section becomes its own file.
