ImgZilla - Image Compressor

About this app

ImgZilla is a 100% local image compressor for macOS. All compression happens on your Mac — your images are never uploaded to any server, keeping your data private and your files safe. **Truly Useful Compression: In-Place Overwrite** Results are written straight back to the original file — same filename, same path, same format. No need to update product links, web code, or archive folders. Originals are moved to the Trash by default, and you can always right-click "Put Back" to restore them — zero risk of mistakes. **See the Quality Yourself — Don't Just Take Our Word** PNG (oxipng) and SVG (svgcleaner) use truly lossless compression — not a single pixel changes. JPEG, WebP, AVIF, HEIC, and GIF use visually lossless tuning (technically lossy re-encoding, but the difference is imperceptible to the eye). A built-in comparison window (⌘D) shows a side-by-side split view, with zoom to actual size for close inspection. You decide if the result is good enough. **Smart Handling, Thoughtful Design** - **All formats supported**: JPG, PNG, GIF, SVG, HEIC, WebP, and AVIF — 8 formats in total. - **True format detection**: Reads the file's magic bytes to detect its real type, so even a mislab
