DropMachine • Reduce Size

DropMachine shrinks oversized PDFs in seconds so they are easier to email, upload, archive, and store. It can also reduce image files when you need a quick cleanup, while PDF compression remains the main workflow. Just drop one or more PDF files, or the occasional JPG, PNG, HEIC, or TIFF image, onto the DropMachine Dock icon or into the app window. DropMachine reduces them locally on your Mac, replaces the original only when a smaller version is actually produced, and keeps a recoverable backup for as long as you choose. Why people choose DropMachine: - Fast drag-and-drop PDF compression - Made for scanned and image-heavy PDFs - Secondary image reduction for JPG, PNG, HEIC, and TIFF files - On-device processing for privacy - Recoverable originals with configurable retention - Recent file history with size-reduction details - Automatic cleanup of temporary backups - Simple workflow with no subscription Built for everyday PDF bottlenecks Large PDFs can block email attachments, portal uploads, client submissions, insurance claims, expense systems, and long-term storage. DropMachine removes the friction without making you open a full PDF editor. What DropMachine does: - Compresses PDFs directly on your Mac - Reduces common image files when they can be made smaller - Works from the Dock for a one-step workflow - Queues multiple files dropped together - Replaces the file only when the result is smaller - Lets you reveal the optimized file, reveal the backup, or recover the original copy - Shows recent files, size changes, and all-time space saved Best results DropMachine works especially well on scanned PDFs, OCR documents, and PDFs that mix text with images. Image reduction is useful for oversized screenshots, photos, and exports. Text-only PDFs or files that are already highly optimized may shrink less, or not at all. Private by default Your files stay on your Mac. No cloud upload required. If your PDF is too big and you want the fastest fix, DropMachine is built for that moment.
