Whether you search Aadhaar card photo size, Aadhar scan size for upload, or Adhar card KB limit — the underlying need is the same: a clear, legible scan that passes automated portal checks. Unlike PAN, you cannot change Aadhaar biometrics online; this guide covers scan uploads and enrolment-form photos where resizing is required.
Typical Aadhaar Upload Size Limits by Portal
Bank KYC / Net Banking
50KB–200KB per side, JPG/PDF
EPFO UAN / PF Transfer
Often 100KB–300KB, clear text
Government Job Portals
20KB–100KB scan, 300 DPI preferred
Scholarship / Education
50KB–150KB, both sides
Insurance / Loan KYC
Under 500KB, readable UID
Physical Enrolment Form Photo
3.5 cm × 4.5 cm passport size
Why Aadhaar Scans Get Rejected
Portals use OCR and image validators. A scan that is too large times out; one over-compressed makes the 12-digit UID unreadable. Glare on the hologram, folded edges, and low-resolution phone snaps are the top rejection triggers — not just file size.
Privacy: Never Upload Aadhaar to Random Sites
Your Aadhaar number plus photo enables identity fraud. Use browser-based tools like OptiKit where processing stays on your device — no cloud storage, no account required.
How to Resize Aadhaar Card Scan for Upload
- Photograph flat — both sides on a dark surface, even light, no flash glare on QR.
- Check portal limit — note max KB and whether JPG or PDF is required.
- Open Aadhaar Card Resizer — set target size (50KB, 100KB, etc.) and 300 DPI if needed.
- Verify readability — zoom in: all 12 digits and name must be sharp.
- Upload to official portal only — never email scans to unknown agents.
Aadhaar Scan Quality Tips
- Shoot at 90° angle — avoid perspective skew
- Include full card with small margin — do not crop UID digits
- Use 300 DPI metadata when portal specifies government scan standards
- Mask last 4 digits only when portal allows; never share full OTP
- For enrolment forms: use 3.5×4.5 cm passport photo, white background
