PDF Squeezer — Mac download

Version 4.9 keeps the same job: shrink PDF files without opening a single settings panel. This build is Intel (x86 64-bit), runs on Apple Silicon through Rosetta 2, and needs macOS 13 or later.

System requirements and compression scope

Most questions before installing come down to two things: where the app works and what it can leave alone. Folder compression covers PDFs inside subfolders, so a batch of invoices or scans does not need manual sorting first. Password-protected files also compress without removing the lock. For web uploads, the smaller output is the point — no export presets, just a smaller file.

Dock it and forget it

A freelance translator receives three marked-up contracts, each touching 20 MB. The client’s portal rejects anything above 8 MB. She drags the folder onto the PDF Squeezer dock icon. The app processes all three files in sequence, keeps the password protection intact, and delivers versions under 3 MB. The translator attaches them to an email and moves on. No export dialogue, no preview — just a folder of lighter files with the original names appended.

Finder Quick Action for one-click compression

The app pairs well with Finder Quick Actions. Select a PDF, right-click, choose PDF Squeezer from the Services menu. The compressed copy lands beside the original. This works without launching the main interface, so a researcher prepping a grant submission can shrink attachments while staying inside a Finder window.

For teams that use Hazel or Automator, the command-line interface opens a quieter door. A shell script can watch a shared folder, compress any PDF that lands there, and move the output to a cloud-synced directory — no manual drag-and-drop required. Think of a design studio where client proofs arrive by email, get saved to a watched folder, and a Hazel rule triggers pdfsqueezer before the files reach the project archive.

macOS integration runs deeper than Quick Actions. The app respects Tags and Spotlight comments: compressed files keep their metadata, so a PDF tagged “urgent” in the Finder stays searchable after processing. iCloud Drive folders work the same as local ones — drop a file stored in iCloud and the squeezed copy syncs back, ready for an iPad or iPhone handoff. For anyone looking to download PDF Squeezer for Mac to plug into an existing workflow, that metadata preservation means the file manager stays in charge.
