Reference Photo Dimension & File Size Specifications (2026)
Online examination portals in India (SSC, UPSC, IBPS, NTA) and international visa authorities enforce binary limits on applicant photograph uploads. Uploading an image even 1 kilobyte above the limit results in automatic system rejection.
Important Notice & Supporting Sources Disclaimer
The presets provided in this tool are algorithmic formatting aids derived from published guidelines (such as the SSC Examination Notice, UPSC Examination Instructions, MEA Passport Seva Photo Guidelines, and US Department of State Travel Specs). Specific examination notices, regional cycles, or consular updates may change pixel dimensions, background colors, date-stamp requirements, or allowed file limits at any time.Always cross-reference your specific official application brochure before final submission. This utility does not guarantee official acceptance.

Why Most Online Photo Compressors Fail Exam Validation
Generic compression websites usually compress images by a crude fixed percentage (e.g. "reduce by 70%"). If your smartphone photo is 8 MB, a 70% reduction leaves a 2.4 MB file—still 48 times larger than the 50 KB threshold.
dontbeac.app solves this with iterative binary-search quantization:
- Our browser engine draws the photograph to an offscreen HTML5 canvas at target pixel dimensions.
- It executes a logarithmic quality convergence loop testing quality steps between 0.05 and 0.98.
- If the image still exceeds the threshold at lowest quality, it dynamically rescales the canvas bounds by 15% intervals until the resulting JPEG strictly conforms to your specified kilobyte budget.
- Zero Privacy Risk: Unlike third-party converter portals that upload your private passport photo and personal likeness to cloud databases, our tool processes 100% of the byte arithmetic locally on your phone or laptop.
