Aadhaar Photo Resizer: 3.5 × 4.5 cm, 200 DPI, Under 200 KB
Make a UIDAI-compliant Aadhaar photo or signature-size image in seconds - entirely in your browser. Nothing is uploaded, nothing is stored, no watermark is added. PixelSize hits the exact KB you need and writes 200 DPI into the file metadata, so portals that check resolution accept it first time.

How to resize an Aadhaar photo to 200 KB in 3 steps
- Upload your photo or scan on the Aadhaar-preset tool page. It never leaves your device.
- Confirm the target - the preset already fills 200 KB and switches to Aadhaar mode (200 DPI, correct dimensions). Adjust the KB if your centre asked for a different size.
- Download the compressed JPG. The summary card shows exactly what changed: dimensions, file size, format and DPI.
Why PixelSize passes where other tools fail
- Exact KB, not "about": a binary-search compressor lands on your target size precisely.
- DPI metadata writer: 200 DPI is written into the JPEG header - most online compressors skip this and get rejected.
- True-size preview: see the original and compressed photo side by side before you download.
- 100% private: processing happens in your browser. No server ever sees your face.
Frequently asked questions
What is the maximum file size for an Aadhaar photo?
UIDAI accepts photos up to 200 KB for enrolment and updates. PixelSize can hit any target from 10 KB to 200 KB exactly.
What dimensions and DPI does UIDAI require?
3.5 × 4.5 cm at 200 DPI, which equals 276 × 354 pixels. Aadhaar mode in PixelSize sets both automatically.
Can I make an Aadhaar photo from my phone camera?
Yes. Stand against a light wall in daylight, keep a neutral face, then let PixelSize fix the size, KB and DPI. HEIC iPhone photos are converted automatically.
Is it safe to process my Aadhaar photo online?
With PixelSize, yes: the file is processed inside your browser and never uploaded to any server, so no one else can access it.
A portal rejected my photo for resolution. Will this help?
Very likely. Rejections often come from missing DPI metadata. PixelSize writes 200 DPI into the JPEG header and sets the exact pixel dimensions UIDAI expects.
Does PixelSize add a watermark or logo?
No. The downloaded photo is clean and ready to upload to UIDAI or any enrolment centre.
