Large MP4 video files can quickly fill up your storage and slow down workflows. TinyFast offers a simple and secure way to compress MP4 on Mac without relying on any online tools. The app works completely offline, reducing video file size instantly while keeping your content private and safe.

Why MP4 Compression Matters

Videos are among the largest file types used in design, development, and content creation. Compressing them helps free up storage, make sharing faster, and improve performance without noticeable quality loss. TinyFast performs this compression locally on your Mac, so your videos are never uploaded or shared externally.
