Compression Quality Comparison
Both Compress Image and Squoosh use industry-standard codecs (MozJPEG, libimagequant for PNG). At the same quality setting, file sizes are comparable. The key difference:
- Compress Image: Simple 0–100% quality slider. Great for quick compression without thinking.
- Squoosh: Granular codec settings (MozJPEG effort level, OxiPNG compression strategy, etc.). Useful for developers or anyone optimizing for specific web performance targets.
Speed and Reliability
- Compress Image: Optimized for batch processing. Handles 5+ images faster than one-by-one.
- Squoosh: Fast for single images. Best-in-class side-by-side preview with zoom.
Bottom Line
Compress Image is better for batch work, target file size compression, and quick uploads. Squoosh is better if you want codec-level control, need to resize images, or want to experiment with AVIF. For most users, Compress Image's simplicity wins; for power users, Squoosh's options shine.
