Technical Specifications & Insights
Image compression reduces file size to save storage space and decrease network transfer times. This tool applies optimization algorithms depending on the file format: JPEG images are optimized by scaling quantization matrices, PNG images are compressed using color-palette reduction and DEFLATE filtering, and WebP images use predictive coding. This allows you to strip unnecessary metadata and optimize pixel storage to make files much lighter without compromising visual quality.
