File tools overview
Ferrocast converts images, audio, video, documents, spreadsheets, subtitles and folders, and edits them with 26 tools and 7 file actions, all on your Mac. Nothing is uploaded. Built-in macOS tools come first (sips, afconvert, avconvert, textutil, ditto); ffmpeg, LibreOffice and cwebp are optional, and a missing one shows its install command.
Drag files and tap a key: ⇧ Shift for conversions, ⌘ Command for file tools, ⌃ Control for file actions. Or press ⌘ T on a file result, run Convert Files, or press ⌥ ↵ on a file result to open the format wheel.
Output rules
Section titled “Output rules”The result is written next to the original with the same base name and the new extension, and never overwrites: if that name is taken, it appends 2, 3 and so on. A toast shows the result with a Reveal action.
