ImageSlim is a free and open source image compression tool that runs on macOS and supports multiple image formats, including .png, .jpg, .jpeg, .heic and .exr. The application has built-in macOS native compression function, and can optionally enable the third-party open source tool pngquant to efficiently compress PNG images, with a compression rate of up to 99%.
Users can quickly import images into the application by dragging and dropping, clicking or pasting images with Command + V. All imported images will be compressed locally immediately to ensure data privacy and not be uploaded. After compression is completed, users can view the images, compare the effects before and after compression, choose to download a single image, or use ZIP batch package to export all images.
ImageSlim provides a wealth of configurable options. Users can adjust the compression rate, set the output directory, enable/disable third-party compression engines, etc. according to their needs. Without enabling pngquant, the application uses the system’s built-in compression capabilities to process images by default to ensure compatibility and processing speed.
This application is completely open source, the source code is hosted on GitHub, and it uses excellent third-party projects such as pngquant and Zip. The picture materials come from Freepik free resources.
ImageSlim is free, ad-free, promises not to upload users’ pictures to third-party servers, and does not actively collect user privacy data. In the unsponsored state, the application limits the import of up to 20 pictures at a time, and the size of a single picture does not exceed 5MB. If ImageSlim is helpful to you, you are welcome to sponsor through the application, and the above restrictions will be lifted after sponsorship.
ImageSlim is an image compression tool that focuses on efficiency, privacy and simple experience. It is suitable for developers, designers, content creators and all people who want to reduce the size of pictures.
