Web vs Desktop

Use web for fast tasks. Download the App for heavy duty.

The browser is great for quick, daily tasks like generating a UUID, verifying a hash, or converting a color. But if you need video/audio conversion, archive compression, larger files, or long batches, the Nua Convert desktop application gives those jobs a native local workspace without browser memory limits.
