Convertify

Open source macOS frontend for FFmpeg. Drag, drop, convert.

Build it yourself · Get it on the App Store

---

What is this?

Convertify wraps FFmpeg in a clean, native interface. No command line needed. It's opinionated where it should be and flexible where it matters.

This project is fully open source. You can clone it, build it, modify it, and use it however you like.

• Drag and drop any video, audio, or image
• Pick a format and hit convert
• Sensible defaults that just work
• Hardware acceleration via Apple VideoToolbox when available

Building

Quick Build

./build-app.sh

This will:

1. Build the app in release mode
2. Create the Convertify.app bundle
3. Generate the app icon
4. Launch the app automatically

Clean Rebuild

If you need to rebuild from scratch (recommended after code changes):

swift package clean
rm -rf .build Convertify.app
./build-app.sh

Or as a one-liner:

swift package clean && rm -rf .build Convertify.app && ./build-app.sh

Build with Xcode

Alternatively, open Convertify.xcodeproj in Xcode and build from there.

Running the App

The build script automatically launches the app. To run it manually:

open Convertify.app

From Finder

Navigate to the project directory and double-click Convertify.app.

Move to Applications (Optional)

To install permanently:

cp -r Convertify.app /Applications/

Then launch from Spotlight or the Applications folder.
