Why Metamorphosis?

🔒

Private by design

Every conversion runs locally on your Mac. Files are never uploaded to external servers and never leave your device.

🧰

One app, many formats

Convert images, audio, video, and documents in one place instead of juggling multiple online tools and apps.

⚡

Native and fast

Drag and drop files, choose output formats, and convert quickly with a focused native macOS experience.

📦

Batch-friendly

Convert single files or batches, choose output folders, and tune quality settings when needed.
