Open-source licenses

ToolHub's local processing is powered by open-source projects, including FFmpeg (LGPL, source available at ffmpeg.org), libheif, MozJPEG, Tesseract and its language models, and the WebAssembly ports that bring them to the browser. Word to PDF typesets non-Latin scripts with Heebo by Oded Ezer, and the site itself is set in Inter by Rasmus Andersson, both used under the SIL Open Font License 1.1: the license texts ship with the fonts, at /fonts/Heebo-OFL.txt and /fonts/Inter-OFL.txt. Full attribution and license texts will be listed here as each engine ships.
