Omniverto: A self-hosted file converter

Most online file converters upload your files to someone else's server. Omniverto is a free converter you can run yourself, with a simple web interface.

It handles more than 450 conversions between image, document, audio and video formats, including RAW camera files and HEIC. Around the converter there are in-browser editors for images, videos, PDFs and LaTeX, plus a CAD and 3D viewer for STL, STEP and DXF files. It is written in Python and runs on my own server.
