When Mac Preview is not enough

Preview is useful for quick PDF work, but its compression controls are limited. If you need a smaller upload-ready PDF while still reviewing quality, use a workflow that makes the size and output route clear.

Pick the compression goal

  • Better quality: Use for portfolios, signed packets, and print-oriented files.
  • Balanced: Use for email attachments, portals, and everyday document sharing.
  • Smallest file: Use when a strict upload limit matters more than visual fidelity.

Privacy check

For supported workflows, the compression route is browser-session based. You can inspect network activity while processing a test file to verify whether uploads occur.

Recommended workflow

  1. Open the Compress PDF tool on your Mac.
  2. Select the PDF from Finder or Downloads.
  3. Choose a compression level based on the destination.
  4. Download the optimized file and compare visual quality.
  5. Keep the original until the compressed copy is accepted.

Quality checks

Open the compressed result and inspect logos, signatures, charts, page scans, and small text. These are usually the first areas where aggressive compression becomes visible.
