How to Compress JPG to 40kb

  • Lossy compression reduces file size dramatically
  • Still maintains decent image quality at small sizes

I compress hundreds of JPG images every month.

This method works consistently.

How Long Does It Take to Reduce the Size of a JPEG Image?

Processing Times:

  • Small images (under 5MB): 5-10 seconds
  • Medium images (5-20MB): 10-30 seconds
  • Large images (20MB+): 30-60 seconds

Factors That Affect Speed:

  • Original file size
  • Your internet connection
  • Image resolution and complexity
  • Whether you’re using a mobile device or computer

Real-World Example: Last week I compressed 50 images for a client’s real estate website.

Each image went from 2MB to 40KB in about 15 seconds.

Total time for the entire batch? Under 15 minutes.

That’s faster than manually resizing even one image in Photoshop.
