FreeScaler
FreeScaler is a macOS image upscaling app that enlarges low-resolution PNG and JPEG images locally using AI models.
What is FreeScaler?
FreeScaler is a native macOS graphics app for enlarging low-resolution images with on-device AI upscaling. It is designed for people who want to improve small photos, scanned pictures, illustrations, and other PNG or JPEG files without sending them to an online service. The app supports single-image work as well as batch processing, so it fits both quick edits and larger folder-based jobs. Its interface lets you compare the original image with the upscaled result, which helps when choosing a model and scale setting. FreeScaler also integrates with Finder so you can start an upscale workflow from the contextual menu. Published by Murus, it is focused on a straightforward local workflow for Mac users who want image enhancement without a cloud account or subscription.

Safety overview
Status: Mostly safe
FreeScaler performs image upscaling locally on your Mac, which is normal for its purpose and can be helpful for privacy because your images do not need to be uploaded to a remote service. Expect it to access the files and folders you choose to import, save, or process from Finder. Batch jobs and AI upscaling can use substantial memory and GPU resources, especially with large images or folders. If you work with sensitive images, review what you import and where you export the results.
Recommendation: Keep FreeScaler if you use it for enlarging photos or artwork on your Mac. If you no longer need AI image upscaling, you can remove it like any other app; doing so will simply stop its Finder-based workflow and local editing features.
