Frequently Asked Questions

Why do exam portals enforce a strict 30KB or 40KB file size limit?

Exam registration systems handle millions of applicants concurrently and enforce strict file size thresholds to prevent database congestion. ImgMin uses iterative bicubic downsampling to hit the exact 30KB target while keeping facial features razor-sharp.

Is it safe to compress sensitive biometric photos with ImgMin?

Yes, 100%. ImgMin Pro executes entirely in your browser using client-side Canvas and WebAssembly. Zero bytes are uploaded to any server, eliminating any risk of identity data theft.

Will compressing to 30KB cause blurry facial features?

No. ImgMin prioritizes high-frequency facial edge retention so that eyes, eyebrows, and contours remain distinctly sharp for biometric machine verification.
