Compress Image to 20KB

A 20KB target is very strict. It usually works only for tiny profile photos, signatures, low-detail logos, or document-system uploads where the display area is small.

Start with dimensions, not quality

Reducing width and height is the fastest way to hit a 20KB target while keeping the image usable. For many website contexts, an image that small should also be shown small.

Best settings to test

• JPG for photographs without transparency.
• WebP when the receiving platform supports it.
• PNG only for simple graphics that need sharp edges or transparency.

When not to force it

If the page needs a cleaner visual result, use a larger allowance like 50KB or 100KB. A harsh limit can do more damage than good when the image is part of a premium-looking page.
