PDFOptim
PDFOptim is a macOS app for compressing and optimizing PDF files so they take up less storage space and are easier to share.
What is PDFOptim?
PDFOptim is a native PDF compression app for Mac that helps users reduce PDF file sizes while keeping documents readable and practical for sharing. It is designed for people who email PDFs, upload documents to websites, store large collections of files, or need smaller files for everyday work. The app supports batch processing, so you can compress multiple PDFs in one session instead of handling them one by one. It also offers automatic compression modes for quick results and manual controls for users who want to adjust image quality and output size more precisely. PDFOptim runs locally on the device for its core file-processing work, which suits workflows where privacy and offline use matter. Published by RootRise Technologies, it fits best as a focused productivity tool for document cleanup and size reduction on macOS.

Safety overview
Status: Mostly safe
PDFOptim’s normal job is to open, read, and save PDF files that you choose, so file access is expected for this kind of app. Its core compression work is described as local processing, which is helpful for privacy when working with sensitive documents. As with any document tool, review the output before replacing originals, especially if you are compressing files that contain scanned images or fine visual detail. Keep backups of important PDFs if exact fidelity matters.
Recommendation: Keep PDFOptim if you regularly need to shrink PDF files for email, uploads, or storage. If you do not use it, removing it is usually reasonable and mainly means losing its compression workflows and any app-specific settings.
