Why Image Compression Matters

Large images slow down websites, increase bandwidth costs, and hurt SEO. Here's how to optimize without sacrificing quality.

Understanding Compression Types

Lossy Compression

Removes some image data permanently. Best for:

  • Web photos
  • Social media images
  • Email attachments

Lossless Compression

Reduces file size without data loss. Best for:

  • Professional photography
  • Print materials
  • Archival purposes

Best Practices for Quality Compression

1. Choose the Right Quality Setting

  • 90-95%: Nearly indistinguishable from original
  • 80-89%: Good balance for web
  • 70-79%: Noticeable quality loss, smaller files

2. Resize Before Compressing

Don't upload a 4000px image if you only need 800px. Resize first, then compress.

3. Use Modern Formats

WebP offers 25-35% better compression than JPG while maintaining quality.

4. Remove Metadata

EXIF data (camera info, GPS) adds unnecessary file size. Remove it for web use.

Pro Tips

  2. Compare Side by Side: Always check quality before publishing
