How to Resize an Image to an Exact KB Size (100KB, 50KB)

Published in Guides · EzSizer Toolkit

The Challenge of Upload Limits

Many government portals, university admissions, and job application sites have strict upload limits. Often, you need your photo or signature to be exactly between 20KB and 50KB. Standard compression tools just give you a 'Quality' slider, making it a guessing game.

The Exact KB Solution

EzSizer uses a binary search algorithm. It repeatedly compresses your image in the background in milliseconds, checking the resulting file size, and adjusting the quality until it hits your exact target size down to the byte. It even uses standard trailing padding if the image is too small!

How to do it

1. Open EzSizer.
2. Select the 'Resize to Exact KB' tool.
3. Upload your photo.
4. Enter your target size (e.g. 50).
5. Download your perfectly sized image.
