About ICO Compression
How it works
Our ICO compressor uses advanced algorithms to reduce file size while maintaining visual quality through adjustable compression levels.
Privacy & Security
All compression happens directly in your browser. Your files are never uploaded to any server, ensuring complete privacy and security of your data.
Quality Control
Adjust the quality slider to find the perfect balance between file size and visual quality for your needs.
Batch Processing
Process multiple ICO files simultaneously. Free users can compress up to 5 files at once, while Pro users enjoy unlimited batch compression.
