Compression Techniques Explained
Our tool uses industry-standard compression algorithms optimized for web performance and visual quality.
Lossy vs Lossless
Lossy compression (JPEG, WebP) discards some image data to achieve smaller files—ideal for photos.Lossless compression (PNG) preserves all original data—perfect for graphics, logos, and screenshots where pixel-perfect quality matters.
- • Lossy: Smaller files, slight quality loss
- • Lossless: Larger files, perfect quality
- • Choose based on image type and use case
JPEG Compression
Uses DCT (Discrete Cosine Transform) to convert image data into frequency components, then quantizes high-frequency details that human eyes are less sensitive to. Quality setting controls how aggressively these details are reduced.
- • Quality 60-70%: Small web thumbnails
- • Quality 80%: Standard web images
- • Quality 90-95%: High-quality photos
PNG Optimization
PNG uses DEFLATE compression (same as ZIP files) with predictive filters to reduce redundancy. Our optimizer applies multiple filter strategies and compression levels to find the smallest possible file without any quality loss.
- ✓ Preserves transparency perfectly
- ✓ Ideal for logos and graphics
- ✓ No generational quality loss
WebP Advanced Compression
Google's WebP format combines the best of both worlds: lossy compression better than JPEG and lossless compression better than PNG. Offers 25-35% smaller files at equivalent quality. Supports transparency and animation.
- ✓ Best compression ratios
- ✓ Both lossy and lossless modes
- ✓ Growing browser support (95%+)
Perceptual Quality Optimization
Our tool analyzes image content to apply more compression to areas where human vision is less sensitive (like smooth gradients) while preserving detail in important areas (like faces and text). This perceptual optimization maximizes compression while maintaining perceived quality.
- • Content-aware compression
- • Preserves important details
- • Optimized for human vision
Target File Size Mode
When you set a target file size (e.g., under 100KB), our algorithm iteratively adjusts compression quality to meet your goal. It starts with moderate compression and fine-tunes until the output matches your target, ensuring optimal quality within size constraints.
- • Automatic quality adjustment
- • Precise file size control
- • Perfect for website requirements
