ICSI student photo and signature size

The ICSI student form takes a photo file of 20 KB–50 KB and a signature file of 10 KB–20 KB, both as JPG/JPEG, PNG, GIF, BMP or PDF. A file of 50,000 bytes or less passes whether the portal counts 1 KB as 1,000 or 1,024 bytes.

ICSI student photo

JPG · 20-50 KB (20,480-50,000 bytes) · original pixel size · white background

PixelFit aims between 20,480 and 50,000 bytes, so the file passes whether the form counts 1 KB as 1,000 or 1,024 bytes.

ICSI student upload specifications

Values for the ICSI student registration (Company Secretary course), copied from ICSI SMASH portal: Student registration instructions, checked 31 October 2026; "not stated" means the source gives no figure for it.

Upload	Pixel size	Print size	File size	Format	Background
Photo	not stated	not stated	20 KB–50 KB	JPG/JPEG, PNG, GIF, BMP or PDF	not stated
Signature	not stated	not stated	10 KB–20 KB	JPG/JPEG, PNG, GIF, BMP or PDF	not stated

What the ICSI student KB limits mean in bytes

The ICSI student photo range of 20 KB–50 KB is 20,480 to 50,000 bytes if you want a file that passes whether the portal counts 1,000 or 1,024 bytes per KB: a window of 29,520 bytes to aim for.

The ICSI student signature range of 10 KB–20 KB is 10,240 to 20,000 bytes if you want a file that passes whether the portal counts 1,000 or 1,024 bytes per KB: a window of 9,760 bytes to aim for.

Largest ICSI student photo under 50 KB

The ICSI student 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 50 KB up to about 461 × 592 px (48.7 KB), so any common camera photo has to be scaled down before it fits.
