Open source

Software we build on

FiveMinFree uses established open-source software where it provides a strong foundation for useful, reliable tools.

PDF tools

The PDF Editor uses Mozilla PDF.js to render PDF pages in the browser and pdf-lib to create and modify exported PDFs. PDF.js is available under the Apache License 2.0 and pdf-lib under the MIT License.

Media and file processing

Server-side tools may use established open-source software including FFmpeg, ImageMagick and LibreOffice for media, image and document processing. Individual projects retain their own licences and copyrights.

Privacy-minded processing

Open-source components do not automatically mean a file is uploaded. Several FiveMinFree tools use browser-side libraries so the work can stay on your device when practical.
