How the 200KB Compression Works
- Binary search on JPEG quality: the tool re-encodes your photo at progressively lower JPEG quality (start at 85%, drop until file fits 200 KB).
- Auto-downscale if needed: if even quality 5% can't reach 200 KB, the tool reduces pixel dimensions in 15% steps.
- Output as JPG: universally accepted by all Indian government and exam portals.
- Browser-only: all work happens in your browser via Canvas API — your photo never leaves your device.
Frequently Asked Questions
What is the Aadhaar photo size?
100-300 KB JPG/PNG. UIDAI doesn't mandate exact pixel dimensions but recommends 600×600 px (1:1 square) for clearest display. Plain background. Recent photo within last 12 months.
Can I update Aadhaar photo online?
Yes for some details (address, mobile, email). For photo update specifically, you must visit an Aadhaar Enrolment Centre — UIDAI doesn't allow remote photo updates to prevent identity fraud. The online "photo upload" is for supporting documents, not the Aadhaar photo itself.
What background for Aadhaar photo?
Plain light background (white or light grey preferred). UIDAI is less strict than Passport — light cream or pale blue acceptable. Use the background remover for a clean white background.
Is my Aadhaar photo public?
No. Aadhaar photo is stored encrypted by UIDAI. e-Aadhaar PDF you download has your photo visible — protect this file. Don't share Aadhaar PDF on social media.
Compress Aadhaar photo without quality loss?
For 200 KB target, JPEG quality remains ~88 — visually indistinguishable from original. The tool maintains face sharpness while reducing file size.
