TinyFast offers a fast and reliable way to bulk compress PDFs on Mac without relying on any online services. The app works entirely offline, enabling you to optimize lots of PDF documents in one go while keeping every file private and secure.

Why Bulk PDF Compression Matters

PDF documents often contain high-resolution images, detailed layouts, or embedded fonts that increase file size significantly. While these features improve readability and quality, they can also slow down file sharing and take up unnecessary space. TinyFast automates the entire process by scanning your selected folders and optimizing every PDF locally, with no uploads or external servers involved.
