## Description

**PDFOptim** provides a straightforward way to compress and optimize PDF documents on iPhone and iPad. It supports Auto Compression with four predefined methods and a Manual mode to customize image color model, resolution, JPEG quality, and vector optimization, all while preserving document integrity. It also features an in-app PDF viewer with search and side-by-side previews for original vs. compressed files.

Sharing and portability are built in: compressed PDFs can be exported as ZIP files, opened in other apps via Open In, shared via AirDrop, or copied to iTunes. The app supports password-protected PDFs and can import documents from other apps. Note: the free version limits exports to one compressed PDF per week; Premium unlocks unlimited exports.
