## Why architects repair a corrupted PDF

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 repair pdf keeps the work inside your private workspace. Designs and client plans are proprietary; private processing protects the practice's work.

## What matters when you repair a corrupted PDF

Repair rebuilds a PDF's cross-reference table and object structure.

It can recover files that won't open due to interrupted downloads or transfers.

Recovery depends on how much of the file is intact.
