100% local, no uploads. Compress images in place — same name, same path. Visually lossless PNG/JPG/WebP/HEIC/SVG, batch processed, fully offline. 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 mislabeled extension (e.g. a PNG that's actually a JPEG) still compresses correctly. - **No pointless compression**: If the savings would be under 0.4%, the file is skipped and marked "Already Minimal" — no wasted re-compression. - **External drive friendly**: Works great with external drives and NAS. If a file can't be moved to the Trash, you can choose a custom backup folder or overwrite directly. **Flexible Privacy & Interface Settings** - **EXIF handling**: Metadata (including GPS location) is stripped by default for smaller, safer files. Want to keep shooting info and color profiles? Turn it on with one tap. - **Multi-language interface**: 19 built-in languages (Simplified & Traditional Chinese, English, Japanese, and more) — switch instantly, no restart needed. **Free Tier & Paid Benefits** The free version compresses 10 images per day (only successful compressions count). Once you hit the limit, tasks pause automatically — get the lifetime unlock or a monthly subscription and it picks up right where it left off, no need to re-add files. Restore your purchase across devices anytime, even after a reinstall. System requirements: macOS 12.3 or later.
