When Should You Use 50KB Instead of 20KB?
A lot of people default to 20KB for everything because it's the strictest requirement they've seen. But if your portal allows 50KB, using 20KB unnecessarily trades away photo quality for no benefit. The rule is simple: compress to the maximum size your portal allows, not the minimum.
Portals where 50KB is the right target
UPSC Civil Services allows up to 300KB — 50KB is a comfortable target that gives you much sharper facial detail than 20KB. At document verification, staff compare your photo to your face. A clearer photo helps. NEET UG allows up to 200KB — same logic. JEE Main through the NTA portal also accepts up to 200KB. For all three, 50KB gives significantly better quality while staying well within limits.
College admissions and scholarship portals
Most Indian university application portals — DU, VIT, BITS, and the National Scholarship Portal — accept photos between 50KB and 200KB. The 50KB target on this page works for all of them. If a specific portal says "under 100KB", the slider on this page can be adjusted to any value between 20KB and 100KB.
State government job portals with 50KB caps
Several state PSC portals — BPSC (Bihar), MPPSC (Madhya Pradesh), and HPSC (Haryana) — allow photos up to 100KB. Use 50KB for a quality-size balance that works universally. BPSC specifically accepts up to 100KB, so either this tool or the 100KB tool works. If in doubt, 50KB is the safer choice for state PSC applications.
⚠️ When to Use 20KB Instead
SSC CGL / CHSL / MTS, Railway RRB NTPC and Group D, and most banking portals (IBPS, SBI) cap photos at 20–50KB with a strict automated checker. For these, use the Photo to 20KB tool on the homepage to stay safely within the limit. Don't use 50KB if the portal cap is exactly 20KB.
