PDF Studio credits & licenses
What the PDF Studio is built with, and the licenses that apply.
What we built
LoschaZ designed and wrote the PDF Studio: the page board, the merge and compression logic, the workspace and these pages. Your files are read, rendered and written in your browser; the libraries below are served from our host, unmodified, and run on your device.
Components & licenses
- pdf-lib 1.17.1 (Andrew Dillon) writes the merged PDF and copies pages without changing them: github.com/Hopding/pdf-lib, MIT License.
- PDF.js 5.4.296 (Mozilla) reads PDFs and renders the previews and the pages that become images: github.com/mozilla/pdf.js, Apache License 2.0. It ships with the Liberation fonts (SIL Open Font License 1.1), the Foxit standard fonts (BSD-style license), OpenJPEG (BSD 2-Clause) and qcms (MIT), and Adobe’s character maps (BSD 3-Clause).
- Outfit and Inter, the typefaces of the site: SIL Open Font License 1.1 and SIL Open Font License 1.1.
