PDFOptim
What PDFOptim is
PDFOptim is a PDF compression and optimization app from RootRise Technologies for macOS, iOS, and Windows. It reduces PDF file sizes while retaining visual quality. Four automatic methods analyze a document and apply a compression algorithm, and a synchronized side-by-side preview lets you compare the original and compressed versions before saving. Manual controls include JPEG quality, image downsampling, color profiles, and removal of hidden metadata.
The Mac app can process PDF folders in batches using multiple CPU cores, with drag-and-drop queues. Scanned documents can be converted to grayscale, monochrome, or bitonal profiles; RootRise says this can produce files up to 40 times smaller. A five-level vector optimization feature removes excess anchor paths and structural data from vector-heavy PDFs. Apple Shortcuts can trigger compression, and RootRise describes a Finder Quick Action workflow.
RootRise says processing runs locally, files are not uploaded, and core features work offline; internet access is used for purchase validation. The free version permits one compressed PDF export per week and restricts Shortcuts Actions. The monthly and yearly plans offer unlimited compressed PDF exports: $0.99 a month or $6.99 a year. Lifetime access costs $9.99, paid once.
