Compress Images for Web & Email

Large image files are a major cause of slow websites and full storage.Compressing images online is the smartest way to optimize your photos for the web, email, or social media. Our tool significantly reduces file size while maintaining excellent visual quality.

Why File Size Matters

Optimized images are essential for digital performance:

  • Website Speed: Smaller images load faster, improving SEO rankings and User Experience (UX).
  • Email Limits: Bypass attachment size limits (e.g., 25MB) by shrinking photos before sending.
  • Storage Space: Free up gigabytes on your phone or cloud storage without deleting memories.

When to Compress Images

Use compression whenever speed or space is a priority:

  • Web Optimization: Shrink header images, banners, and product photos to improve Core Web Vitals (LCP).
  • Social Media: Ensure your uploads are fast and don't get crushed by aggressive platform algorithms.
  • Archives: Reduce the footprint of scanned documents or photo backups.
