ImgZilla: Mac Image Compression Tool, In-place Compression Without Changing File Paths
Core Features and Design Philosophy
ImgZilla is a macOS image compression tool that also provides an online compression entry. The reviewer's original words are that the macOS client "focuses on local processing and in-place compression." This means that after compression, the original file is directly replaced, with the filename and directory structure remaining unchanged. This is very practical for projects that already have a large number of references.
The Advantage of In-place Compression
Using traditional online tools to compress images generally involves the steps of "Upload → Download → Replace → Update References." ImgZilla handles everything locally, eliminating these steps. You can simply drag in an entire folder, and it will recursively process the images in batch. The reviewer believes it is particularly suitable for developers maintaining WordPress media libraries, GitHub projects, or frontend code.
Supported Image Formats
| Format | Compression Method |
|---|---|
| PNG | Lossless |
| SVG | Lossless Optimization |
| JPEG / WebP / AVIF / HEIC | Visually Lossless |
| GIF | Supported |
Note that the tool does not have a slider to manually adjust compression quality; the entire optimization process is fully automatic.
