Features
Simple conversion, done locally.
Built on AVFoundation and ImageIO, so there are no command-line tools to install and nothing leaves your Mac.
Video, audio and image formats
Video to MP4 (H.264), MP4 (HEVC) or MOV. Audio to M4A, WAV or AIFF. Images to JPEG, PNG, HEIC or TIFF.
Presets for size and quality
Choose 1080p, 720p or Original Size for video, and a quality slider and maximum dimension for images. Set defaults in Preferences.
A queue with live progress
Up to two conversions run at once, each with its own progress bar and Cancel button. Reveal in Finder appears when a row is done.
Never overwrites your files
Output goes next to the original or into a folder you choose. If a name is taken, a counter is added, like name 2.mp4. Cancelled or failed jobs leave no partial file.
Extract audio from video
Videos with an audio track can be exported straight to M4A, WAV or AIFF. Files without audio are reported clearly instead of failing silently.

FAQ
Questions, answered.
Is DropMediaConverter really free and open source?
Yes. It is released under the MIT license, and the full source is in the GitHub repository. There are no ads, accounts or paid tiers. If it saves you time, an optional Support button links to Ko-fi.
Does it need any special permissions?
No. It does not ask for Accessibility, Screen Recording or Microphone access. It only reads the files you drop or pick, and writes output next to them or in the folder you choose. macOS may show its usual prompt for protected folders.
Where is my data stored?
Your files stay where they are, and converted copies are saved next to the originals or in your chosen folder. The app makes no network calls and has no analytics. Only your default settings are saved in standard macOS preferences.
Why isn't the app notarized?
Notarization requires a paid Apple Developer account, and this is a free project. Right-click the app and choose Open once to get past Gatekeeper, or build it yourself from source with Xcode and XcodeGen.
Was this written by AI?
Yes. DropMediaConverter was generated by Claude Code from a written spec as a clean-room reimplementation, with no code or assets from any commercial app. The full source is on GitHub under MIT, so you can read every line before you run it. It has had less human review than a hand-written app, so bug reports are welcome.
