When Should You Use 100KB?
100KB is the standard ceiling for visa application photos, corporate HR portals, and several defence recruitment portals. The US DS-160 B1/B2 visa form requires a JPEG photo under 240KB — 100KB gives excellent quality with comfortable headroom. The UK Standard Visitor visa has a 120KB guideline. For most Indian applicants going through visa applications, 100KB is the safest and best-quality choice.
NDA and AFCAT applications accept photos up to 200KB — a 100KB file lands in the safe middle range with sharp quality. Private company HR portals — Infosys, TCS, Wipro, and most IT company campus hiring forms — typically accept 100KB to 500KB. A 100KB file works universally across all of them without guessing each portal's limit.
At 100KB, the algorithm doesn't need to reduce dimensions significantly — it mainly optimises the JPEG encoding. The photo you download will look nearly identical to the original on screen, which is why visa interviewers and HR staff rarely flag photos compressed to this size.
Portals That Need 100KB — and Why Quality Matters Here
100KB is the right target when the portal has a higher size limit and quality actually matters for the outcome. Visa applications, defence exam shortlisting, and corporate HR uploads all fall into this category. A slightly blurry 20KB photo on a government job portal is usually fine — a blurry photo on a US visa application is a different problem.
US Visa (DS-160) and international visa applications
The DS-160 form for US B1/B2 visa requires a JPEG photo under 240KB — 100KB is the standard recommended target because it gives excellent quality without approaching the ceiling. UK Standard Visitor visa has a similar guideline. The photo goes to a consular officer who physically examines it — image clarity directly affects the process. Start with a high-resolution original for best results at 100KB.
NDA, AFCAT, and Services Selection Board portals
Defence recruitment portals through SSB and the Services Selection Board accept photos between 20KB and 200KB. 100KB gives sharp facial features that hold up well during physical document verification — which is more rigorous for defence selections than for most civilian exams. AFCAT uses the IAF portal which similarly accepts up to 200KB.
Corporate and campus recruitment portals
Infosys InfyTQ, TCS iON, Wipro NLTH, and most company HR portals accept photos up to 500KB. 100KB covers all of them. The same compressed photo also works for LinkedIn profile uploads and most Indian job portals like Naukri.com which allows up to 5MB but recommends smaller files for faster loading.

- 20KB: Clear enough for automated portal check — face recognisable, works for SSC, Railway, IBPS
- 50KB: Noticeably sharper — good for UPSC, NEET, JEE where portal allows more
