Compress JPEG Images — Free

JPEG compression specifically optimizes the most common photo format for smaller file sizes while preserving photographic quality. Our specialized JPEG compressor uses advanced encoding techniques that reduce files by 40-80% with minimal visible quality loss.

JPEG compression works by reducing detail in areas where the human eye is least sensitive—subtle color variations and high-frequency patterns. The quality slider gives you precise control over the compression/quality tradeoff. Higher quality preserves more detail for printing and archiving, while higher compression creates smaller files for web and email.

Photographers compress JPEGs for web galleries and client proofing. Real estate agents optimize listing photos for MLS uploads with size limits. Event coordinators compress event photos for faster sharing and downloads. Travel bloggers compress vacation photos to fit hosting bandwidth limits. Marketing teams optimize product photography for e-commerce platforms.

Our JPEG optimizer uses mozjpeg, an enhanced JPEG encoder developed by Mozilla that produces smaller files than standard encoders at equivalent quality levels. Additional optimizations include Huffman table optimization, progressive encoding for faster perceived loading, and optional metadata removal for maximum compression.
