Most file converters make you upload your files to a website. convt runs on your own computer instead. Right-click a photo, video, audio file or document, pick a format, and the new file appears next to the original. It handles 40 formats, from HEIC and MOV to PDF and DOCX, works offline and converts whole folders at once. Want more control? Set quality and size in the app, or script it with the convt command line tool. Open source, with a 7-day free trial.
