The swiss army knife of lossless video and audio editing without re-encoding.

LosslessCut is a high-performance, cross-platform video and audio editing utility designed for surgical precision without the overhead of re-encoding. Architecturally, it serves as a sophisticated Electron-based graphical interface for FFmpeg, enabling users to perform 'stream copying' operations. By manipulating the underlying bitstream instead of decoding and re-encoding frames, it maintains 100% original quality and operates at the speed of disk I/O. As we move into 2026, LosslessCut has solidified its position as a critical tool for AI data preparation—specifically for computer vision engineers who need to extract clean, uncompressed training segments from massive datasets. Its support for a vast array of containers (MP4, MOV, WebM, MKV, OGG, WAV) and its ability to extract specific streams (subtitles, multi-track audio) without synchronization loss makes it indispensable for professional workflows. Unlike traditional Non-Linear Editors (NLEs), LosslessCut does not require rendering, making the export process nearly instantaneous even for 4K/8K RAW footage. Its lightweight footprint and lack of cloud dependency ensure data privacy and maximum operational efficiency for edge-computing developers and privacy-conscious creators.

Explore all tools that specialize in ffmpeg gui. This domain focus ensures LosslessCut delivers optimized results for this specific requirement.
Utilizes FFmpeg's -codec copy functionality to transfer data packets without re-encoding.
Experimental re-encoding of only a few frames around cut points to achieve frame-accurate cuts while keeping the rest lossless.
Integration of FFmpeg blackdetect filter to identify scene changes or commercial breaks automatically.
Recursive copying of EXIF, GPS, and creation time metadata during the cut process.
Interactive GUI to discard or re-order specific audio tracks and subtitle streams.
Export cut timestamps and segment data into machine-readable formats.
Optimized seeking algorithm that jumps between keyframes for rapid navigation through multi-gigabyte files.
Download the binary for your OS (Windows, macOS, or Linux) from GitHub or App Stores.
Launch the application; no installation is required for the portable version.
Drag and drop a video or audio file into the main interface.
Use the 'I' and 'O' keys to set start and end points for segments.
Add multiple segments to the list for batch cutting or merging.
Use the 'Tracks' menu to toggle specific audio, subtitle, or data streams on/off.
Preview segments using the high-speed player (Keyframe-seeking enabled).
Set the output folder and naming convention in the settings tab.
Click 'Export' to begin the lossless stream copy process.
Verify the output files; the process is usually complete in seconds regardless of file size.
