How to compress a passport photo to 15 KB

NYSC online registration asks for a passport photograph saved under 15 KB, and other forms set similar limits for signatures. This page is set to 15 KB and keeps the photo as clear as that size allows.

  1. Crop the photo to head and shoulders, then add it here.

  2. Check the size box shows 15 KB.

  3. Click Compress images and check the KB and pixel size shown before you upload.

A passport photograph in 15 KB

The best-known 15 KB rule is NYSC online registration in Nigeria, which asks for a passport photograph saved under 15 KB. A phone photo is hundreds of times larger, so the picture will be scaled down as well as lowered in quality; that is unavoidable at this size. What you control is how much of the frame is face. A square crop of head and shoulders against a plain white or off-white wall leaves little for the compressor to throw away.

After compressing, the result shows the final size in KB together with the width and height in pixels. Expect a small image, a few hundred pixels on each side at most; that is normal for a 15 KB photograph.

If the photo looks blurred

Blur at this size nearly always traces back to the original picture:

  • Retake it in daylight, facing a window; grain from a dim room uses up bytes that should go to your face.
  • Stand close to a plain wall so the background is one even tone, with no furniture, curtains or shadows.
  • Crop in your phone's gallery to a square around head and shoulders before adding the photo; this tool compresses but does not crop.
  • For a signature with a 15 KB cap, crop to the ink alone; it fits far more easily than a face does.
