Your images stay on your Mac — only the size shrinks
Images too big to send or eating up disk space? Drop them into ImgZilla and they shrink instantly — up to 90% smaller with quality intact. Originals go to the Trash so you can always recover them, and 100% local processing means not a single pixel is uploaded.
Supports all major image formats
Image compression built for real work
From privacy to batch processing, ImgZilla shrinks file size effectively while keeping quality and privacy intact.
Privacy first, processed locally
Compression runs entirely on your Mac — no network, no cloud upload. Not a single pixel leaks, so sensitive material stays safe.
Smooth batches, drag and drop
Whether a handful of images or a whole folder, just drop them in. Multi-threaded processing gets through large batches fast.
Strong compression, quality intact
Deep optimization tuned per format keeps images sharp while averaging over 50% compression, up to 90%+.
Broad format support
Handles JPG, PNG, GIF, SVG, HEIC/HEIF, WebP, AVIF and other mainstream formats in one place.
Automatic original backup
Originals can be saved to the Trash before compression, recoverable anytime — compress with confidence.
Before / after comparison
The built-in image compare tool shows exactly what changed, with trackpad pinch and scroll to zoom and pan around the cursor.
Big savings, complete peace of mind
The built-in image compare tool lets you see exactly how each image changed, with trackpad pinch and scroll zooming around the cursor. Originals are backed up to the Trash and recoverable anytime, so compression comes with no regrets.

“I run project image assets through ImgZilla first — they end up less than half the size, and first paint is visibly faster.”
“Originals get backed up to the Trash automatically, so I never worry about over-compressing — I can always get the original back.”
“The built-in compare tool shows the before/after clearly — the difference is barely visible, and AVIF's file sizes are stunning.”
