TrimrPixImageOptim Alternative for Mac
TrimrPix is a modern ImageOptim alternative for Mac. It supports JPEG, PNG, GIF, WebP, AVIF, and HEIC with drag-and-drop batch compression, Watch Folder automation, and adjustable quality — all fully offline for $1.99 one-time.
Why look for an ImageOptim alternative?
ImageOptim is a well-known free image optimizer for Mac. It works well for basic JPEG and PNG compression. However, some users need features that ImageOptim does not offer — like AVIF support, a Watch Folder that auto-optimizes new files, or an adjustable quality slider for fine-tuning compression.
TrimrPix is built as a modern native Mac app with these features included.

Format support
TrimrPix handles JPEG, PNG, GIF, WebP, AVIF, and HEIC in one interface. This means you can optimize all modern image formats without switching tools. For a deeper look at when to use each format, see the Image Formats Guide.
Batch compression and Watch Folder
Both TrimrPix and ImageOptim support batch processing — drag in multiple files and optimize them all at once. Where TrimrPix goes further is Watch Folder: set any folder on your Mac to be monitored, and new images added to it are optimized automatically.
This is ideal for screenshot folders, download directories, or export folders from design tools. Learn more in the Batch Image Compression guide.
Pricing
ImageOptim is free and open-source. TrimrPix costs $1.99 one-time on the Mac App Store — no subscription, no in-app purchases. The paid model supports ongoing development and new features.
Who should switch?
Consider TrimrPix if you need:
- AVIF, WebP, or HEIC support — modern formats that ImageOptim does not handle
- Watch Folder automation — auto-optimize without manual drag-and-drop
- Quality control — an adjustable slider (60%–95%) to balance file size and quality
- App Store updates — automatic updates through the Mac App Store
