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.
Key features
Lossy PNG Compression
Reduces PNG file sizes by 50-80% using smart color reduction while maintaining visual quality imperceptible to the human eye.
JPEG Optimization
Strips metadata and applies advanced compression algorithms to reduce JPEG file sizes by 40-60% without artifacts.
Batch Processing
Upload up to 20 images simultaneously through web interface, or unlimited via API for programmatic optimization.
Developer API
RESTful API with PHP, Ruby, Python, and Node.js libraries for integrating compression into development workflows.
WordPress Integration
Official plugin automatically compresses images on upload and can bulk optimize existing media libraries.
Photoshop Plugin
Export directly from Photoshop with TinyPNG compression applied, streamlining design-to-web workflows.

FAQ
How much can TinyPNG reduce image file sizes?
PNG files typically compress 50-80% while JPEG files see 40-60% reductions. Actual compression depends on image complexity and color palette.
Does TinyPNG affect SEO rankings directly?
No, but smaller images improve page load speed and Core Web Vitals scores, which are confirmed Google ranking factors.
Can TinyPNG handle WebP format?
No, TinyPNG only supports PNG and JPEG formats. For WebP optimization, consider Cloudinary or ShortPixel.
Is the compression reversible?
No, TinyPNG uses lossy compression that permanently removes data. Always keep original files as backups.
What's included in the free tier?
500 image compressions per month through the web interface, with no API access or plugin functionality.
