Typical photo and signature limits
Exam bodies and document authorities usually publish a PDF or information bulletin with exact specifications. Those instructions are always the final reference point. However, candidates often find the wording confusing or need a quick reminder while sitting at a cyber café. The table below summarises the ranges most people encounter in practice.
Aadhaar Card Photo Requirements (UIDAI)

Aadhaar Card Photo Resize Online – UIDAI Guide
The Unique Identification Authority of India (UIDAI) mandates specific photo requirements for Aadhaar card enrollment and updates. Whether you're updating your address, name, or photo, the uploaded image must meet the portal's validation checks.
How to Resize Photo for Aadhaar Update
- Take a clear photo: Use a white background with even lighting. Remove spectacles and caps.
- Upload here: Our tool accepts JPEG and PNG formats.
- Target 200KB: This ensures high quality within the 500KB upper limit.
- Download and upload: Use the resized image on the UIDAI or myAadhaar portal.
Common Aadhaar Photo Issues
- "File too large": Most camera photos are 2-5MB. Our compressor reduces them to under 500KB.
- Blurry after resize: Always start with a high-resolution original for best results.
- Wrong format: The portal accepts both JPEG and PNG. We output JPEG by default.
Who this online tool helps
This page is designed for candidates and applicants who already have a decent quality photo but are stuck on the final upload step. Instead of visiting a studio every time an exam notification appears, you can prepare compliant files yourself in a few minutes.
- Citizens updating Aadhaar photo through myAadhaar portal or Aadhaar Seva Kendra.
- Aadhaar correction applicants who need to upload a new photograph.
- Parents updating children's Aadhaar card photos after age 5 or 15.
- NRIs updating Aadhaar details online from abroad.
Step-by-step: prepare your image
- Capture or scan clearly. Use natural daylight or soft indoor light. Avoid harsh shadows, coloured bulbs and heavy filters.
- Crop to the right framing. Your head and shoulders should be comfortably inside the frame with a little space above the head. For signatures, crop to just the handwriting on white paper.
- Open the main PhotoResizer.in tool. Use the quick links in the header or go directly to the image resizer page.
- Select a suitable target KB value. If your notification states 20–50KB, you can safely start with 40–45KB to maintain clarity, or pick a lower option if the portal is very strict.
- Keep aspect ratio locked. This protects your picture from looking stretched when reduced to exam dimensions.
- Download and zoom in to verify. Open the final file, zoom in on your face or signature, and make sure edges remain sharp and text is readable.
Practical tips before final submission
Once your image is ready, a few small checks can save you from last-minute technical issues:
- Test the upload once on a desktop browser and once on mobile, if possible.
- Keep both the original and resized images in a clearly named folder so you can reuse them for future forms.
- Avoid editing the file further in apps that may enlarge it again or change the format.
