Spec score 7.7 #21 of 39 in PDF Compression Software

What it is

PDFOptim compresses and optimizes PDF files to reduce their size while retaining visual quality. Four automatic methods analyze a document and apply a compression approach, while a synchronized side-by-side preview lets users compare the original and compressed files before saving. Manual controls include JPEG quality, image downsampling, color profiles, and hidden metadata removal. The Mac app can process folders in batches using multiple CPU cores and 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 the maker describes using the app as a Finder Quick Action. RootRise says processing runs locally, files are not uploaded, and core features work offline; internet is used for purchase validation. The free version allows one compressed PDF export per week and restricts Shortcuts Actions. Premium plans are $0.99 a month, $6.99 a year, or $9.99, paid once.
