Resize Image to KB

Make your photo or signature fit exam and government form limits — exact KB and pixel size.

Photo and signature size for common exams

Requirements change with every notification, so always check your exam's official instructions. Typical limits look like this:

FormPhotoSignature
SSC (CGL, CHSL, MTS)20–50 KB, JPG10–20 KB, JPG
Banking (IBPS, SBI)20–50 KB, 200×230 px10–20 KB, 140×60 px
UPSC20–300 KB, JPG20–300 KB, JPG
Railway (RRB)20–50 KB, JPG10–40 KB, JPG

How it works

The tool resizes your image to the pixel size you choose, then finds the highest JPG quality that keeps the file under your KB limit. If the limit is very small, it reduces the dimensions slightly as well. Everything happens in your browser — your photo is never uploaded.

Tips

  • Use a recent photo with a plain, light background and good lighting.
  • For signatures, sign in black ink on white paper and crop tightly before resizing.
  • Need to reduce many photos at once? Try the image compressor.
