Aadhaar Photo Size and Rules: What UIDAI Flows Actually Accept (Free Checks)
Aadhaar is unusual among Indian ID systems: for enrolment and biometric update, the photo is taken live at the centre on UIDAI equipment, so there is nothing for you to prepare. The confusion starts with online flows, myAadhaar document updates, Aadhaar-PAN linking screens and third-party forms that ask you to upload a face photo or a scan of your Aadhaar letter.
This guide separates what UIDAI captures from what you must upload, lists the working bands recent flows have used, and shows how to prepare a clean, compliant file without handing your Aadhaar scan to a random website.
What UIDAI captures versus what you upload
Enrolment and biometric updates capture your photo, fingerprints and iris live at the centre. No user-supplied photo enters that process, so no size preparation is needed there.
Online flows are different: document update requests, some bank and telecom KYC re-verifications that reference Aadhaar, and printable Aadhaar letter scans all involve files you produce yourself.
- Enrolment centre: live capture, nothing to prepare.
- Online document update and KYC re-verification: your scan or face photo, with size and format rules.
- Aadhaar letter print or scan: treat it as a sensitive document, never upload it to converters that keep copies.
Working bands for face photos in update flows
Face photos requested alongside Aadhaar updates commonly follow the standard Indian ID band: JPEG around 3.5 x 4.5 cm framing, held between 10 and 200 KB depending on the portal, with a plain light background and a neutral expression.
Where a flow states its own numbers, those win. Prepare a mid-band file near 50 KB and you sit inside almost every window without re-encoding.
- Format: JPEG for photos, PDF or JPEG for letter scans where accepted.
- Background: plain light, no shadows behind the shoulders.
- Framing: head and shoulders centred, chin to forehead fully inside the crop.
Preparing the photo without risking the document
- Capture square-on to a window with even light on your face, against a plain wall.
- Crop head-and-shoulders and place it on a clean white background with the background tool, which runs in your browser.
- Compress into the stated KB window with a measured compressor, not a guessing slider.
- For Aadhaar letter scans, mask or share only the fields the flow actually needs | the full letter with your number is identity material.
- Every step above runs client-side | your face photo and Aadhaar scan never leave your device.
Rejections and how to pre-empt them
The usual Aadhaar-adjacent rejections are not about the number on the file: shadow gradients behind the head, spectacles glare, blurred rescans of prints, and stretched crops that change the face ratio all fail reviewer checks even when the KB value is perfect.
Flat light, a true white background, and a crop that keeps the original aspect ratio remove nearly all of them before compression.
If a flow rejects a file that meets every stated rule, re-run the preset rather than editing the exported file by hand | re-encoders on the portal side expect a clean JPEG stream.
