What LosslessCut is

LosslessCut is a free desktop video and audio editor for Linux, macOS, and Windows. It cuts and copies streams without re-encoding, preserving the source quality, and supports trimming, cutting, merging, concatenation, and combining tracks from multiple files. The app can extract tracks, remux compatible formats, capture full-resolution JPEG or PNG snapshots, and change rotation metadata. Its timeline includes zoom, frame or keyframe jumping, thumbnails, and an audio waveform. Users can label segments, save them in projects, and exchange segment data through CSV, CUE, XML, and chapter-mark formats. LosslessCut serves as a graphical interface for FFmpeg, keeps a modifiable log of recent commands, and lists a basic command-line interface and HTTP API. Common formats include MP4, MOV, WebM, Matroska, OGG, and WAV, depending on codecs and file details. Privacy information says personal data is not collected and settings remain on the computer.

Who it suits

LosslessCut suits desktop users who need fast, quality-preserving media cuts and joins on Linux, macOS, or Windows. It also fits users who want FFmpeg access, segment files, or automation interfaces.

Verdict

LosslessCut offers broad lossless editing and FFmpeg-based controls at no cost. Its key limitation is keyframe-rounded cuts, so it is unsuitable when frame-exact timing is required.
