Free Image Compressor

Why Compress Images?

Large images are one of the most common causes of slow websites. A page that takes more than 3 seconds to load loses over half its visitors. Compressing images reduces file size without significant loss of visible quality — making your site faster and your Google rankings better.

• Faster page load — smaller images download faster, especially on mobile
• Better SEO — Google uses page speed as a ranking factor
• Lower bandwidth — reduces hosting costs and data usage
• Better Core Web Vitals — improves LCP (Largest Contentful Paint) scores

How the Image Compressor Works

This tool uses your browser's built-in Canvas API to re-encode images at a lower quality setting. All processing happens locally on your device — your images are never uploaded to any server.

• Upload your image (JPG, PNG, WebP, GIF, BMP)
• Adjust the quality slider — lower = smaller file, higher = better quality
• Choose the output format (JPG, PNG, or WebP)
• Click Compress — preview both versions side by side
• Download the compressed image in one click

Compression Tips

• JPG at 70–80% — ideal for photos. Barely visible quality loss, significant size reduction.
• PNG — use for images with text, logos, or transparency. PNG compression is lossless.
• WebP — best overall format. Smaller than JPG at the same quality, supports transparency.
• Start at 70% quality and reduce until the preview looks acceptable for your use case.
