What is AVItools?
AVItools is a native macOS video utility for working with AVI media files. It provides a graphical interface for common video-processing tasks so users can create, edit, convert, and join AVI videos without relying entirely on command-line tools. Typical use cases include preparing AVI files for playback, changing encoding settings, combining clips, and handling subtitle-related workflows alongside related tools in the same suite. The app is aimed at users who manage legacy or mixed-format video libraries and want focused controls for AVI containers and streams. AVItools is published by Emmgunn and is part of the VIDEOtoolbox family of Mac video applications.

Safety overview
Status: Mostly safe
AVItools is a legitimate video-processing app for macOS. It works on media files you choose, so it may read and write large video files and create related processing logs or settings data as part of normal use. That file access is expected for a converter and editor. Use it with copies of important videos if you are changing formats or joining files, since re-encoding or muxing can overwrite output targets or produce results you may want to review before replacing originals.
Recommendation: Keep AVItools if you still edit, convert, or join AVI-based video files on your Mac. If you no longer use it or no longer work with AVI media, you can remove it to free space, and any related preferences or support files can also be cleaned up if you do not need to preserve its settings.
