Aadhaar photo size requirements: a complete guide

The exact specifications

For Aadhaar enrolment and biometric updates, the Unique Identification Authority of India accepts a passport-style photograph with these specifications:

• Dimensions: 3.5 cm × 4.5 cm (35 mm × 45 mm)
• File size: Most online portals accept up to 100 KB. Some legacy enrolment systems still cap at 50 KB or even 20 KB. The mAadhaar app accepts up to 100 KB.
• Format: JPEG (the universally accepted format)
• Background: Plain white or off-white. No patterns, gradients, or coloured backdrops.
• Face coverage: Face should occupy 70–80% of the frame, centered horizontally, eyes roughly one-third from the top.
• Recency: Must be a recent photograph — UIDAI guidance says within the last 6 months.

How to take a usable photo

A smartphone camera is fine. Stand 1–1.5 meters from a plain white wall in even, soft light — facing a window during daytime is ideal. Avoid direct overhead lighting that creates shadows under your eyes and chin. Look directly at the camera with a neutral expression, mouth closed, eyes open, eyebrows visible. Hair should not cover your eyes or eyebrows. Spectacles are allowed if they don't have heavy frames or reflections; tinted lenses are not.

Common rejection reasons

• Background not white. Even a slight cream or beige tint can fail. Use a plain white wall, white sheet, or white screen.
• Smiling or showing teeth. Aadhaar photos must be neutral expressions.
• Wearing accessories. Sunglasses, hats, caps, dupatta over hair are not accepted. Religious head coverings are allowed if they don't obscure facial features.
• Photo too dark or too light. Auto-exposure on phones can over-expose against a white wall, blowing out skin tones. Tap on your face to set exposure manually.
• Photo too small or too pixelated. If you've already compressed it heavily, restart from the original.
• Wrong aspect ratio. Phone cameras default to 4:3 or 16:9. Aadhaar wants approximately 7:9. Most photo-resizing tools centre-crop automatically.

What to do if your file is too large

This is the most common issue. A modern smartphone JPEG can easily be 3-5 MB, while Aadhaar portals accept up to 100 KB. Three options:

• Use a browser-based resizer. Tools that compress to a target KB (like our Aadhaar Photo Resizer) do this automatically. The compression happens in your browser, not on a server, so your photo doesn't leave your device.
• Use phone built-in editor. Most Android and iPhone gallery apps let you "save lower-quality copy" — usually drops 5 MB to under 1 MB but rarely under 100 KB.
• Don't email it to yourself "to compress". Email attachments are not the same as a true resize — Gmail can attach 25 MB happily, and the Aadhaar portal will still reject it.

Photo for online vs in-person enrolment

If you're booking an enrolment appointment at an Aadhaar Seva Kendra or post office, the operator will photograph you fresh on their webcam — you don't need to bring or upload a photo at all. The 3.5×4.5 cm photo is needed for: online address updates, photo updates after age 5/15 (mandatory biometric refresh), online correction requests, and PVC card orders.

Tools we recommend

Use any browser-based resizer that processes images locally — meaning no upload to a server. This protects the privacy of your face photo. Once you have a 50–100 KB JPEG with a white background and 3.5:4.5 aspect ratio, you're set.
