How to Compress an Image to 20KB
Job portals, visa and exam applications, and many web forms cap photo uploads at 20KB. Upload your image and the tool searches for the highest quality setting whose file size stays at or below 20KB. If even the lowest quality is too large, it reduces the pixel dimensions step by step until the file fits. Images already under 20KB are returned untouched.
