How to Compress Images Online
Image compression reduces file size without significantly affecting visual quality. Smaller images load faster, improve SEO rankings, and save bandwidth.
Why Compress Images?
Google uses page speed as a ranking factor. Compressed images load faster, improve Core Web Vitals scores, and reduce bounce rates. Smaller files also save hosting storage and bandwidth costs.
Lossy vs Lossless Compression
Lossy compression removes some data permanently — smaller files but some quality loss. Lossless compression reduces size without quality loss — larger files than lossy but perfect quality.
Optimal Quality Settings
- Web photos: 70-85% quality — imperceptible difference, 50-70% size reduction
- E-commerce: 80-90% quality — balance between quality and load speed
- Print: 90-95% quality — minimal compression for high-resolution output
