Your Aadhaar card, issued by the Unique Identification Authority of India (UIDAI), is your primary proof of identity and address. If you need to update your biometric details or upload a scanned copy of your Aadhaar card to a bank or government portal, you must follow specific formatting rules. This guide explains the official Aadhaar requirements and document upload specifications.
Aadhaar Photo Update — Official Requirements
If you are updating your photograph at an Aadhaar Seva Kendra, the operator will capture it live. If you are uploading a scanned photo to the myAadhaar portal, it must meet these standards:
- Format: JPEG/JPG format only.
- File Size: Must be under 2MB for portal uploads.
- Dimensions: Clear square crop of at least 200x200 pixels (standard passport photo layout).
- Background: Solid white or very light grey.
- Visibility: Full face visible, neutral expression, eyes open.
How to Update Aadhaar Photo Online (myAadhaar Portal)
To update your details on the UIDAI portal, log in at myaadhaar.uidai.gov.in using your Aadhaar number and OTP. Select the update option, upload the scanned supporting documents, pay the fee, and book an appointment at a local center for biometric validation.
How to Compress Aadhaar PDF for Bank KYC Upload
Many banks and financial portals require your Aadhaar PDF to be under 200KB or 500KB. Scanned documents are often much larger, but you can compress them easily with ResizeKB:
- Go to our Aadhaar PDF Compress tool.
- Upload your e-Aadhaar PDF. Enter your password if prompted.
- Download the compressed, optimized copy. It remains fully readable for official KYC verification.
How to Merge Aadhaar Front and Back on One Page
Most portals require both sides of your card on a single page. Uploading separate files is often not supported. You can merge them easily into a single page PDF or JPEG using our Merge Aadhaar Front & Back utility.
Is It Safe to Upload Aadhaar to Online Compressor Tools?
Uploading Aadhaar files to external servers poses significant security risks. ResizeKB processes your files entirely locally in your browser. Your data is never uploaded or saved, keeping your personal information completely private.
