Advanced JPEG Compression Techniques

Understanding the impact of the quality slider is essential for maintaining a high-performance website. Each percentage point on the slider represents a specific level of Quantization in the JPEG algorithm.

How Quality Affects File Size

When you set the quality to 60%, the compressor aggressively removes high-frequency color information that is less visible to humans. However, if you drop below 30%, you will notice "blocky" artifacts. For professional use, we recommend staying between 70-80% to ensure your Core Web Vitals remain optimized without sacrificing user experience.
