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

Arthize lets designers and creative 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 designers split a PDF by bookmarks

A designer sends a proof as a fixed PDF, exports selected pages to high-resolution PNG for a client preview, and compresses the print layout for email approval — keeping the originals private.

**Built for proofs.** Whether it's proofs, portfolios, print layouts, Arthize's split pdf by bookmark keeps the work inside your private workspace. Client work and unreleased designs are confidential; private processing keeps proofs off public tools.

## 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.
