LosslessCut

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:

• Lossless trimming and cutting of video and audio files, with labeled segments and CSV export/import for edit decision lists
• Merge and concatenate multiple files with identical codec parameters, no re-encoding required
• Stream editing: pull tracks from multiple files and combine them into one output
• Remux into any compatible container format, such as converting an MKV to MP4 or TS to MOV
• Extract tracks individually, whether that's audio, video, or subtitles
• Full-resolution snapshots exported as JPEG or PNG
• Audio waveform and video thumbnails in the timeline for easier orientation
