Mac app converts video, audio, and images entirely on your own computer
A developer built a Mac app that converts video, audio, images, GIFs, and image sequences without sending files to any server. Everything happens locally on your Mac, so your files never leave your device.
Most online file converters require you to upload your files to a third-party server, which raises privacy concerns — especially when dealing with client materials or sensitive business assets. This app runs entirely on your Mac, meaning no uploads, no internet required, and no risk of your files being stored or seen elsewhere.
It supports a wide range of formats including video, audio, images, GIFs, and image sequences. For solo business operators, this is a practical tool for converting product photos, client videos, or marketing assets without relying on a paid subscription service or worrying about data privacy.
