TinyPNG
Image OptimizationSmart PNG and JPEG compression without visible quality loss
Overview
TinyPNG pioneered smart PNG compression when it launched in 2014, using quantization algorithms that reduce color palettes while preserving visual quality. The Amsterdam-based company expanded to JPEG optimization and now processes billions of images annually for developers and content creators focused on page speed optimization.
Unlike simple file compression tools, TinyPNG analyzes each image's color distribution and applies selective lossy compression. For PNGs, it reduces the color palette from 24-bit to 8-bit while using smart dithering to maintain visual fidelity. JPEG processing strips unnecessary metadata and applies perceptually optimized compression that targets areas less sensitive to human vision.
The tool integrates into existing workflows through its web interface, API, and plugins for WordPress, Photoshop, and other platforms. This makes it particularly valuable for teams managing high-volume image optimization without manual intervention.

“The #1 killer of site speed? Unoptimized images. They destroy your LCP score and send mobile users running. The fix: • Compress before uploading (use TinyPNG) • Convert to WebP format (60% smaller files) • Enable lazy loading (built into WordPress now) • Set image dimensions (prevents layout shift)”
