What the India Post GDS KB limits mean in bytes

The India Post GDS photo limit of 50 KB is 51,200 bytes when 1 KB = 1,024 bytes and 50,000 bytes when 1 KB = 1,000 bytes; a file of 50,000 bytes or less passes either way.

The India Post GDS signature limit of 20 KB is 20,480 bytes when 1 KB = 1,024 bytes and 20,000 bytes when 1 KB = 1,000 bytes; a file of 20,000 bytes or less passes either way.

Largest India Post GDS photo under 50 KB

The India Post GDS 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.
