About Resize Image to KB
Online forms often say your photo must be under 50KB or your signature under 20KB. This free tool lets you resize an image to an exact KB size, so your file is accepted the first time. Choose a target like 20KB, 50KB or 100KB. Everything runs in your browser, and your image stays on your device.
It is made for real form uploads: job applications, government portals, university admissions, exam registrations and visa forms. Use it for your photo, your scanned signature or a copy of your CNIC or Iqama. Many people in Pakistan and the Gulf use it when a portal keeps rejecting a file for being too large.
