User Reviews

Formattery is nice file converter, especially for quickly handling different formats without relying on online tools. One feature I’d really love to see is a Mac menu bar mode, because it would make opening the app and converting files much faster and more convenient in daily use.

This app is incredibly useful! I love that everything converts 100% on-device, so my files stay private with no uploads. It handles 80+ formats including images, documents, video, and even ebooks & 3D models. The batch conversion and quality adjustment are lifesavers. Best of all: no subscription, just a one-time Pro upgrade. Highly recommend!
