ImageOptim
ImageOptim is a macOS image optimization app that shrinks PNG, JPEG, and GIF files by removing extra data and improving compression.
What is ImageOptim?
ImageOptim is a macOS utility for reducing image file sizes without changing the visible quality more than necessary. It helps web designers, developers, bloggers, and anyone preparing images for websites, apps, or sharing use smaller files that load faster and take up less storage. The app works with common formats such as PNG and JPEG, and it can process files by simple drag and drop. It also removes unnecessary metadata such as EXIF information, which can help reduce size and avoid sharing embedded location or camera details when exporting images for the web. For users who need more control, ImageOptim includes preferences for keeping certain metadata or adjusting which optimization tools are used. ImageOptim is published by Kornel Lesinski and is focused on fast, straightforward image compression workflows on Mac.

Safety overview
Status: Safe
ImageOptim is a legitimate Mac utility for local image optimization. It needs access to the files you choose so it can rewrite them with smaller versions, and that access is normal for its purpose. Because it modifies the selected images in place, keep backups of important originals if you may need the unoptimized versions later, especially when preserving metadata matters to your workflow.
Recommendation: Keep ImageOptim if you regularly prepare images for websites, apps, email, or storage savings on your Mac. Remove it if you no longer use it for image compression, but remember that uninstalling the app will not restore images that were already optimized.
