5 Ways to Reduce Image File Size

1. Compress the Image

Reduce quality slightly without noticeable visual difference. JPG compression can reduce file size by 70-90%.

Recommendation: Use 80-85% quality for JPG. Virtually no visible difference but much smaller files.

2. Resize Dimensions

Reduce pixel dimensions. A 4000x3000 image resized to 2000x1500 is 4x smaller with little quality loss.

Recommendation: For web use, 1920x1080 is plenty. For email, 1200x900 is often enough.

3. Convert Format

PNG to JPG conversion can reduce file size by 50-80%. Use JPG for photos, PNG only when transparency is needed.

Recommendation: Convert PNG to JPG for photos. Keep PNG for logos and graphics with transparency.

4. Use Modern Formats

WebP and AVIF formats are 25-35% smaller than JPG with same quality. Great for websites with modern browser support.

Recommendation: Use WebP for web. Provide JPG fallback for older browsers.

5. Remove Metadata

Photos contain EXIF data (camera info, GPS, etc.) that adds kilobytes. Removing it slightly reduces file size.

Recommendation: Strip metadata for privacy and small file size reduction (usually 10-50KB).
