Why Compress Images?
Faster Page Load
Images often account for 50%+ of page weight. Smaller images mean faster loading times and better user experience.
Better SEO
Google uses page speed as a ranking factor. Optimized images help improve your Core Web Vitals and search rankings.
Lower Bandwidth Costs
Smaller images reduce CDN and hosting costs. Less data transfer means more savings at scale.
How It Works
Your images are processed entirely in your browser - nothing is uploaded to any server
We use canvas-based compression to reduce file size while maintaining visual quality
Images are converted to JPEG or WebP for maximum compression - PNG can't be compressed with quality settings
Download your compressed images instantly - no waiting, no account required
