Browser-based, open source video editor built for privacy. No installs, no account required, works on any platform.

OpenCut is an open source video editor that runs entirely in your browser. Nothing to install. No account to create. Because it works in the browser, it runs on Windows, macOS, and Linux without platform-specific builds or compatibility headaches.
The focus is on keeping things simple. The interface is designed to feel approachable rather than overwhelming, which makes it a practical option for people who need to edit video without learning a complex tool. That said, "simple" here doesn't mean stripped-down. The goal is to cover real editing needs without the friction that comes with heavyweight desktop software like Kdenlive or Shotcut.
Privacy is a core part of the design. Processing happens locally in the browser rather than on a remote server, so your footage never gets uploaded to a third-party service. For anyone editing sensitive or personal video, that's a meaningful difference from cloud-based editors that process files on their own infrastructure.
Being open source means the codebase is publicly available for inspection. You can verify what the tool actually does with your files, and the project can be self-hosted if you want full control over where it runs.
OpenCut suits content creators, journalists, educators, or anyone who edits video occasionally and wants a fast, private, no-install option that works from any device with a modern browser.

Desktop app for lossless video and audio editing. Cut, trim, merge, and remux files in seconds without re-encoding, using FFmpeg under the hood.

Most video editors re-encode your footage every time you make a cut. That process can take hours and degrades quality with each pass. LosslessCut skips re-encoding entirely. It cuts the data stream directly, so trimming a large file takes seconds instead of hours, and the output is bit-for-bit identical to the source.
It runs on macOS, Windows, and Linux, and handles a wide range of formats thanks to FFmpeg doing the heavy lifting underneath. The interface is built around a timeline with zoom, frame jumping, and keyframe jumping, so you can navigate precisely without touching the command line.
Key capabilities include:
One important caveat: cuts are aligned to the nearest preceding keyframe, not to the exact frame you select. For most use cases (removing commercials, trimming intros, splitting long recordings) this is fine. For frame-perfect editing, a re-encoding editor like Kdenlive or Shotcut would be more appropriate.
The app is free to download from GitHub. Paid versions are available through the Mac App Store and Microsoft Store for users who want signed binaries and automatic updates, or who want to support the developer.
