Features
Massive Size Reduction
Reduce image file sizes by up to 80% using advanced compression algorithms while preserving visual quality.
Strip Metadata
Remove EXIF data, GPS coordinates, camera info, and other metadata to protect your privacy and reduce file size.
Batch Processing
Drag and drop multiple images at once. Process entire folders of images in seconds with progress tracking.
Quality Control
Fine-tune compression quality with an intuitive slider. Preview results before saving to find the perfect balance.
Format Conversion
Convert between JPEG, PNG, HEIC, and WebP formats. Choose the best format for your needs.
Safe Processing
Create optimized copies by default, keeping your originals safe. Optional in-place replacement for power users.
Advanced Compression Engines
SlimPix uses industry-leading open-source compression libraries
🚀 MozJPEG
Mozilla's optimized JPEG encoder produces files 5-10% smaller than standard encoders with no quality loss. Uses advanced Huffman table optimization and progressive encoding.
✨ Zopfli
Google's Zopfli algorithm creates the smallest possible PNG files. Takes longer but achieves 3-8% better compression than standard deflate - completely lossless.
🍎 Native Encoders
Fall back to Apple's built-in encoders for maximum speed when you need quick results. Full support for HEIC and WebP formats.
