The information and tools on SizeToKB (sizetokb.in) are for general guidance only.
Not an official exam body
SizeToKB is an independent free utility. We are not affiliated with SSC, UPSC, NTA, IBPS, RRB, state PSCs, banks, or any recruiting organisation. Official notifications always override any sizes shown here.
Verify before you submit
Photo size (e.g. 20KB–50KB), signature size (e.g. 10KB–20KB), dimensions (cm/px), and format (JPG/JPEG) can change every recruitment cycle. Always cross-check the latest PDF notification and the live application portal before uploading.
No guarantee of acceptance
A file that meets the KB range on SizeToKB may still be rejected due to portal-side validation, crop rules, live photo capture, background colour, face detection, or other checks outside our control.
Technical limitations
Compression quality depends on your source image. Extremely small, blurry, or already heavily compressed photos may not land inside a portal's min–max KB window.
