Third-party software licenses

QuickToolio is built on several open-source libraries. Most are permissively licensed (MIT, Apache, BSD) and need no special action. This page documents the two that carry a copyleft license (GPL/LGPL) and where their corresponding source code is published.

• FFmpeg (with libx264), GPL-2.0-or-later: the video and audio tools use a custom, codec-minimal build of FFmpeg, compiled by us from the unmodified official source. The corresponding source code, the exact build recipe, and verification checksums are published at github.com/ikergm00/quicktoolio-ffmpeg-core-build, with a copy archived under our own control in its v2.0.0-quicktoolio release.
• heic-to (wrapping libheif), LGPL-3.0: the HEIC to JPG and HEIC to PNG tools use this library unmodified, loaded dynamically. Its source code is published by its author at github.com/hoppergee/heic-to.

For any question about these licenses, write to us at contacto@quicktoolio.com.
