    Image Optimizer 2.1 — Now in Your Terminal

    Image Optimizer now ships with imgopt, a command line tool that uses the same bundled optimizers as the app. Script your image pipeline, optimize a folder before a commit, or just stay in the terminal. 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.

    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.

    Image Optimizer — The Big Comeback

    Four years later, Image Optimizer is back. This is more than a fresh coat of paint: the app now has a completely redesigned interface, a smoother optimization workflow, and a modernized foundation.

    Compression You Can Actually See

    The new workspace keeps the entire process in view: original and optimized sizes, total savings, processing time, and the status of every file.

    The interactive before-and-after comparison makes checking the result just as easy—select an image and drag the slider to inspect every detail.

    Everything You Need, Right Where You Need It

    Optimization controls now live alongside your files. Adjust JPEG and PNG quality, choose the output format, strip metadata, and control where the results are saved without leaving the workspace.

    You can now:

    • Keep the original format or convert JPEG and PNG images to WebP
    • Strip image metadata
    • Choose a custom output folder name
    • Add a .min suffix or replace the original files
    • Drop individual images or entire folders for batch processing

    Updates Without the Treasure Hunt

    Image Optimizer can now notify you when a new version is available, show the download progress, and install the update after restarting the app.

    Fresh Under the Hood, Too

    Electron, Vue, TypeScript, and the build toolchain have all been brought up to date. We also strengthened communication between the interface and the operating system and rebuilt the release pipeline for macOS, Windows, and Linux.

    In short: it’s still the fast, private Image Optimizer you know—just much nicer to use, easier to understand, and more reliable.
