Questions

Good to know.

Is Nabi really free?

Yes. No account, no ads, no subscription. Download it, drag it into Applications, and it's yours.

macOS says it can't check Nabi. Is that safe?

Nabi isn't from the App Store yet, so the first time you open it macOS asks you to confirm. Open System Settings → Privacy & Security, scroll down and click Open Anyway. You only do this once.

Which Macs does it run on?

Macs with Apple Silicon on macOS 14 Sonoma or later.

Does Nabi upload my files?

Never. Every conversion happens on your Mac with Apple's own frameworks, and Nabi works without an internet connection.

Why does it ask for Accessibility?

That's what lets Nabi notice ⌃⌘ and see which file you've selected or are dragging. Nabi never reads what you type.

Do I need anything else installed?

No. Pages documents go through Apple's free Pages app, and a handful of extra video and audio formats (WebM, MKV, burned-in captions, 9:16) use a small optional add-on Nabi installs for you.

Why a butterfly?

Nabi (나비) is Korean for butterfly. Butterflies are all about transformation, and so is Nabi. It also flaps its wings while it works, which we consider essential.

Your files deserve better
than upload sites.

Nabi is free. Download it, and the butterfly is one ⌃⌘ away.

Download Nabi for Mac
FreemacOS 14 Sonoma or laterApple Silicon
  1. 1

    Open the download

    Drag the butterfly into your Applications folder.

  2. 2

    Say hello once

    macOS asks you to confirm apps from outside the App Store: System Settings → Privacy & Security → Open Anyway.

  3. 3

    Allow Accessibility

    So Nabi can hear ⌃⌘. Then select any file and press it.
