Shrink everyday files, clean hidden Office document bloat, and find large files inside folders you choose—all in one focused native utility. COMPR3SS is a native Mac utility for reducing file size and reclaiming storage space without juggling separate tools for every format. Drag in files or folders, preview the result, compare original and compressed sizes, and save a smaller copy when you are ready. COMPR3SS supports common business, creative, and media formats, including PDF, PNG, JPEG, HEIC, TIFF, GIF, SVG, MP4, MOV, M4V, WAV, AIFF, DOCX, XLSX, PPTX, Pages, Numbers, Keynote, and ZIP. SMART COMPRESSION • Add individual files or entire folders • Preview compressed results before saving • Compare original and compressed file sizes • Tune available quality and compression settings by format • Keep originals untouched unless you explicitly choose to replace them OFFICE DOCUMENT CLEANUP Reduce unnecessary package data in Word, Excel, and PowerPoint files. COMPR3SS can remove safe-to-discard document bloat such as embedded fonts, thumbnails, printer settings, custom properties, and editing-session metadata while preserving the document package. FIND WHAT IS USING YOUR SPACE Use Discover to locate large supported files indexed by Spotlight inside a folder you choose. Filter by size and send chosen files directly to the compression queue. BUILT FOR macOS COMPR3SS is designed for the Mac with drag and drop, Finder integration, native previews, keyboard-friendly controls, and an interface that stays out of your way. Compression results depend on file contents and format. Files that are already highly compressed may not become smaller.
