IGNOU photo and signature size

The IGNOU form takes a photo file of at most 100 KB and a signature file of at most 100 KB, both as JPG/JPEG. It also takes supporting documents (at most 200 KB).

IGNOU photo

JPG · under 100 KB (at most 100,000 bytes) · original pixel size · white background

PixelFit aims at 100,000 bytes or less, so the file passes whether the form counts 1 KB as 1,000 or 1,024 bytes.

Saving presets is part of Pro.

Pick a photo to fit it to under 100 KB (at most 100,000 bytes).

The result appears here: the exact byte count, pixel size and quality, the size before and after, a preview and a download button.

IGNOU upload specifications

Values for the IGNOU online admission, copied from IGNOU Admission Portal: Frequently Asked Questions, checked 31 October 2026; "not stated" means the source gives no figure for it.

What the IGNOU KB limits mean in bytes

The IGNOU photo limit of 100 KB is 102,400 bytes when 1 KB = 1,024 bytes and 100,000 bytes when 1 KB = 1,000 bytes; a file of 100,000 bytes or less passes either way.

The IGNOU signature limit of 100 KB is 102,400 bytes when 1 KB = 1,024 bytes and 100,000 bytes when 1 KB = 1,000 bytes; a file of 100,000 bytes or less passes either way.

The IGNOU supporting documents limit of 200 KB is 204,800 bytes when 1 KB = 1,024 bytes and 200,000 bytes when 1 KB = 1,000 bytes; a file of 200,000 bytes or less passes either way.

Largest IGNOU photo under 100 KB

The IGNOU source gives a file-size limit but no pixel size for the photo. Measured on a public-domain portrait, a 7:9 (35 × 45 mm shape) JPG at quality 85 stays under 100 KB up to about 716 × 920 px (97.5 KB), so any common camera photo has to be scaled down before it fits.

IGNOU rejection checklist

Upload checks computed from the IGNOU specification; a file that fails any one of them is usually refused at upload or flagged later.

  • Photo: File type is JPG/JPEG (a PNG or HEIC renamed to .jpg is still rejected).
  • Photo: The IGNOU photo file is no larger than 100 KB (100,000 bytes is safe under both KB definitions).
  • Signature: File type is JPG/JPEG (a PNG or HEIC renamed to .jpg is still rejected).
  • Signature: The IGNOU signature file is no larger than 100 KB (100,000 bytes is safe under both KB definitions).
  • Supporting documents: File type is JPG/JPEG or PDF.
  • Supporting documents: The IGNOU supporting documents file is no larger than 200 KB (200,000 bytes is safe under both KB definitions).

What the IGNOU source also says

  • Photo: Recent passport size photograph.

IGNOU compared with similar forms

Of these 5 forms, the IGNOU photo limit of 100 KB is the strictest, level with GST registration and CTET; a file made for a stricter form usually passes a more generous one only if it also meets the minimum and the pixel size.

Where the IGNOU figures come from

Verify with the official IGNOU notice before you submit: forms change between application cycles and the check on the live portal is final.
