What is convertisseur-fichiers?

Convertisseur de fichiers is a simple command line tool for converting files on your own computer, so you never have to upload personal files to an unfamiliar website just to change their format. Everything runs locally, which matters if you care about keeping your documents, photos, or videos off someone else's server. The tool covers four kinds of conversion. It can switch image formats such as PNG, JPG, and WebP. It can merge several PDF files into one. It can convert audio between formats like MP3, WAV, OGG, and FLAC, and video between formats like MP4, AVI, MOV, and MKV. There is also an option to convert every file in a whole folder at once, which saves you from running the same command over and over on individual files. For people who are not comfortable typing commands, the project also includes a graphical application, described in the README as built for people who find command line tools difficult to use. To install it, you clone the repository from GitHub, move into the project folder, and install the Python dependencies listed in the requirements file. Audio and video conversion also depend on ffmpeg, a separate free program that needs to be installed on your system first. Once set up, using the tool is a matter of running a single Python command with your input file and desired output file as arguments, for example converting a PNG photo to JPG, or turning a video from MP4 to AVI. The project is licensed under MIT, so it can be used, modified, and shared freely, including in commercial projects, as long as the original copyright notice stays attached.
