ICMR Asian-Specific Health Cut-Offs
Our BMI calculator features ICMR (Indian Council of Medical Research) cut-offs, where South Asian metabolic risk begins at a BMI of 23 rather than the Western 25 benchmark.
Govt Exam & Portal Presets (UPSC, SSC, IBPS)
Instant image compression targeting strict 20KB, 50KB, 100KB, or 200KB thresholds in WebP, PNG, and JPG formats for seamless passport and government application uploads.
