📦 Compress Image

Reduce file size without losing quality — all in your browser

🔒 Your image never leaves your device. All processing happens locally in your browser using browser-image-compression (Web Worker). No upload, no server, no tracking.

Features

  • Smart Compression — AI-assisted compression reduces file size significantly while preserving visual quality.
  • Size Comparison — See original vs. compressed file size and the exact percentage saved.
  • Visual Comparison — Side-by-side preview so you can verify quality is maintained.
  • Web Worker — Compression runs in a background thread — the UI stays responsive.

How It Works

  1. Upload your image — Drop any JPG, PNG, or WebP image to compress.
  2. Review results — See the size reduction and compare original vs. compressed quality side by side.
  3. Download compressed image — Save the smaller file — perfect for websites, emails, and faster loading.

Use Cases

  • Optimize images for faster website loading (Core Web Vitals)
  • Reduce file size for email attachments
  • Shrink photos before uploading to social media
  • Save storage space on your device
  • Speed up image-heavy web pages

Frequently Asked Questions

How much can I reduce the file size?

Typically 50-80% reduction for JPEGs and 30-60% for PNGs, depending on the image content and original compression level.

Is there visible quality loss?

The algorithm optimizes for perceptual quality. In most cases, the difference is imperceptible to the human eye even at significant size reductions.

What's the maximum file size?

There's no hard limit since processing happens locally. However, very large files (50MB+) may take a few seconds longer.
