Empowering Simple & Lossless Video Editing
Our mission is to provide the most reliable, secure, and up-to-date distribution channel for MP4Joiner—the world’s favorite open-source tool for merging videos without quality loss.
Born from the Open Source Community
MP4Joiner is a core component of the MP4Tools project, originally envisioned and developed by Alex Thüring. The software was created to solve a common digital headache: how to join video files without the agonizingly slow process of re-encoding.
Driven by the GNU General Public License (GPL), MP4Joiner has evolved through years of community feedback. This license ensures that the software remains free for everyone—forever—protecting users from the hidden costs and privacy invasions often found in proprietary alternatives.
