Image Compressor

The tool reduces file size by removing redundant data. Lossy compression (JPG): reduces quality slightly for major size savings (60-90% reduction). Lossless compression (PNG): reduces size without quality loss (10-50% reduction). The tool shows before/after comparison.

JPG quality 80-85%: best balance of quality and size for web. Quality 60-70%: acceptable for thumbnails. Quality 90%+: minimal compression, large files. The tool shows file size at each quality level. Most users cannot see differences above 80%.

JPG: typically 60-80% size reduction at quality 80. PNG: 10-50% with lossless optimization. WebP: 25-35% smaller than equivalent JPG. A 5 MB photo can often be reduced to 500 KB-1 MB with no visible difference at web viewing sizes.

Lossy (JPG, WebP lossy): permanently removes data for smaller files. Cannot recover original quality. Lossless (PNG, WebP lossless): reduces size without data loss. Original quality is preserved. Choose based on whether you need to edit the image later.
