How to check and set photo file size in KB for exam form
Exam portals check the file size of your uploaded photo in kilobytes (KB). A typical requirement is "20KB minimum, 50KB maximum". Here's how to check your current photo size and resize it to the exact KB range.
Step-by-step fix
How to check file size in KB (Windows)
Right-click the photo file → Properties. Look for "Size" under the General tab. It shows KB or MB.
How to check file size in KB (Android)
Open Files or My Files app. Long-press the photo → Details or Properties. File size is shown.
How to check file size (iPhone)
In Photos app, tap the photo → swipe up to see Details. Or use Files app → long-press → Get Info.
Resize to target KB range
Open the photo resize tool. Select your exam preset. The tool automatically compresses to the exact KB range required.
Common causes and fixes
Photo is too large (500KB–5MB)
Run through the resize tool — it compresses to your exam's required range in one step.
Photo is too small (under minimum KB)
Most portals only have a maximum, not a minimum. If there is a minimum, the tool ensures the KB is above it.
Not sure what KB your exam requires
Select your exam in the tool — the requirements are shown with the preset applied.
Frequently asked questions
What is the photo KB requirement for SSC CGL?
SSC CGL requires 20KB minimum, 50KB maximum, JPG format, 200×230px. Select SSC CGL in the resize tool for auto-apply.
What is the difference between KB and pixels?
Pixels (px) are the dimensions — width × height. KB is the file size — how many kilobytes of data. Both are checked by exam portals separately.
My photo is 48KB but the portal says "file too large — max 50KB". Why?
The portal may count differently (e.g. including metadata). Try the resize tool with max set to 45KB to give a small margin.
