convertfile43

2026 · live · github

Convertfile43 is a free macOS menu bar app that batch converts audio, video, images, and documents without opening a window.

When I switched to Mac I could not find a simple file converter like file-converter.io on Windows, a right-click context menu tool that just works. So I made this. Copy files in Finder, click the menu bar icon, pick a format. Converted files appear next to the originals.

It ships with FFmpeg, ImageMagick, Ghostscript, and Potrace bundled. No Homebrew needed. Supports hardware-accelerated video via VideoToolbox on supported Macs.
