They can include data shared with other apps and cannot be restored, and it does not guarantee that nothing is left. Back up any data you need first. To keep settings and caches, leave out `--zap`.

No Node.js or extra installs needed. #### Get the Command - **macOS:** choose **Image Optimizer → Install Command Line Tool…** to add `imgopt` to `/usr/local/bin`. Move the app to Applications first. - **Windows:** the installer adds `imgopt` to your user `PATH`. Open a new terminal after installing. The app doesn't need to be running for the command to work. #### A Guided Mode for When You Don't Remember the Flags Run `imgopt` on its own. It asks what to optimize, where the results should go, whether to convert to WebP, which quality to use, and whether to keep metadata. Before it starts, it prints the equivalent command so you can skip the questions next time. ```sh imgopt # guided mode imgopt ./images # writes to ./images/minified imgopt photo.jpg --webp -s # writes minified/photo.min.webp imgopt ./assets --in-place -y # replace originals without asking imgopt ./images --json # machine-readable report ``` #### Safe by Default - Replacing original files asks for confirmation in the terminal and requires `--yes` in scripts and CI. - Clear exit codes: `1` when any file fails, `2` on invalid arguments, `130` when you decline or cancel. - A progress bar in the terminal, and plain output when piped. #### Also in This Release - Default PNG quality is now 85 for new installs. Existing settings are kept. Run `imgopt --help` for all options. #### What's Changed - feat(cli): add imgopt command line tool by @antonreshetov in https://github.com/antonreshetov/image-optimizer/pull/40 **Full Changelog**: https://github.com/antonreshetov/image-optimizer/compare/v2.0.2...v2.1.0 ## Facts and sources - - - · Checked 2026-11-08 - - · Checked 2026-11-07
