Image Compressor

How Image Compression Works

Image compression reduces file size by removing unnecessary data or using efficient encoding. This tool uses lossy compression techniques that maintain visual quality while significantly reducing file sizes.

Features:

• Batch compression - compress multiple images at once
• Adjustable quality settings with presets
• Optional image resizing for additional size reduction
• Real-time preview and statistics
• Download individual images or all at once
• 100% client-side processing - images never leave your device
• Support for PNG, JPG, JPEG, and WebP formats

Compression Presets:

• High Quality (95%) - Minimal compression, best for print or archival
• Balanced (80%) - Good balance between quality and file size
• Aggressive (60%) - Significant compression for web use
• Maximum (40%) - Maximum compression for thumbnails or previews

Best Practices:

• Use 80-90% quality for photos intended for web display
• Enable resizing if images will be displayed smaller than original size
• PNG images benefit most from conversion to JPG or WebP
• WebP format offers superior compression compared to JPG
• Always keep original files as backup before compression
