LosslessCut
The swiss army knife of lossless video/audio editing
Thanks to my supporters and everyone who purchased LosslessCut!
For Linux these are some alternatives:
If you prefer to download the executables manually, this will of course always be free:
- Mac OS X: Intel DMG / Apple Silicon DMG (note that universal.pkg does not work)
- Windows: 7zip (Windows 7, 8 and 8.1 is no longer supported after v3.50.0)
- Linux: x64 tar.bz2 / x64 AppImage / arm64 tar.bz2 / Raspberry Pi armv7l
- More releases (note that APPX for Windows and PKG for MacOS do not work)
If you find LosslessCut useful, I'm very thankful for your support.

Supported operating systems
Supported formats
LosslessCut uses Chromium's HTML5 video player, and not all FFmpeg supported formats and codecs are natively supported. Generally, the following formats should work: MP4, MOV, WebM, Matroska, OGG and WAV. The following audio codecs: FLAC, MP3, Opus, PCM, Vorbis and AAC. Video codecs: H264, AV1, Theora, VP8, VP9 and H265 (needs hardware decoder). More information about Chromium supported formats / codecs. What's the difference between a codec and a format?
Codecs and formats not listed above can still be converted to a supported format/codec from the File menu. (Try the fastest option first.) A low quality version of the file (with/without audio) will then be created and opened in the player. The actual cut/export operation will still be performed on the original file, so it will be lossless. This allows for potentially opening any file that FFmpeg is able to decode.

Typical workflow
- Drag drop a video file into player or use ⌘/CTRL+O.
- Press SPACE to play/pause or ◀▶, ,. or mouse/trackpad wheel to seek back/forth.
- Select the cut segment's start and end time by moving the time marker and then pressing I to set start time, and O to set end time.
- Note that all segments you create will be preserved and exported as new files. You can change this behavior with the Yin Yang symbol ☯️, in which case it will instead remove all selected segments and export the parts between segments.
- Note also that start times will not be accurate, see Known issues
- (optional) If you want to add more than one segment, move to the desired start time and press +, then select the next segment start/end times with I/O.
- (optional) If you want to re-merge all the selected segments into one file after cutting, toggle the button
Separate files to Merge cuts.
- (optional) If you want to export to a certain output folder, press the
Working dir unset button (default: Input file folder)
- (optional) If you want to change orientation, press the rotation button
- (optional) By default, audio, video and subtitle tracks from the input file will be cut and exported. Press the
Tracks button to customise and/or add new tracks from other files.
- (optional) select a new output format
- (optional) In the right-hand segments panel, right click a segment for options, or drag-drop to reorder. Segments will appear in this order in the merged output.
- When done, press the
Export button (or E) to show an overview with export options.
- (optional) adjust any export options
- Then press
Export again to confirm the export
- Press the Camera button (or C) if you want to take a JPEG/PNG snapshot from the current time
- If you want to move the original file to trash, press the trash button
- For best results you may need to trial and error with another output format (Matroska takes nearly everything), change keyframe cut mode or disable some tracks (see known issues).
- Press SHIFT + / to view all keyboard & mouse shortcuts.
- Note: The original video file will not be modified. Instead, a file is created file in the same directory as the original file with from/to timestamps in the file name.
