Managing large sets of images can quickly fill up your storage and slow down your projects. TinyFast provides an easy way to bulk compress images on Mac without uploading them to the internet. The app runs fully offline, allowing you to optimize hundreds of PNG or JPEG files in one go while keeping every file private and secure.

Why Bulk Image Compression is Important

Images make up a large portion of most app and website assets. High-resolution images improve quality, but they also increase storage use and loading times. Compressing them in bulk saves space and improves performance without affecting visual fidelity. TinyFast automates this process, scanning all images in your selected folders and optimizing them instantly.
