Image Compressor
Compress JPG, PNG and WebP images without visible quality loss.
What is Image Compression?
Image compression reduces file size by removing redundant data from the image. There are two types: lossless compression (no quality loss, smaller reduction) and lossy compression (some quality loss, significant size reduction). This tool uses advanced lossy compression optimized to minimize visible artifacts.
How to Use This Tool
- Upload one or more images (JPG, PNG, or WebP).
- Use the quality slider to set your desired compression level.
- Preview the compressed result alongside the original.
- Download the compressed image.
Why Compress Images?
Uncompressed images slow down websites significantly. Google PageSpeed Insights flags oversized images as a top performance issue. Compressing images before uploading to your website or CMS can cut load times by 50–80%, improving both user experience and SEO rankings.
Tips for Best Results
- Start at quality 80 — most users cannot see the difference at this level.
- For images with flat colors (illustrations, screenshots), PNG compression is more efficient than JPG.
- Always keep your original file before compressing.
