Useful Optimization Tips for Resize Image Dimensions in Pixels
- Online exam portals often mandate exact dimensions such as 200×230px (passport photo) or 140×60px (signature).
- Keep 'Lock Aspect Ratio' checked to prevent unnatural stretching or squishing of your face.
- Downscaling images before file compression ensures clean lines and prevents blurry compression artifacts.

Frequently Asked Questions
What is the difference between resizing and compressing?
Resizing changes the physical pixel dimensions (width × height). Compressing reduces the file weight in KB/MB. For strict portal uploads, resizing dimensions first makes it much easier to hit tight KB limits like 20KB or 50KB.
