OCI Photo Resizer Online — 350x350 & 51x51mm Signature Fix

Targeting the "Black Hole" of OCI Upload Errors

If you are applying for an OCI (Overseas Citizen of India) card through VFS Global or the official Indian Government Portal, you know how frustrating the image upload process is. The portal often throws errors like "Invalid Dimensions" or "Unsupported File Format".

This is because modern iPhones take photos in HEIC format, while Indian portals only accept JPG/JPEG.

⚡ OCI Quick Specs:
  • Photo Size: 2x2 inches (51x51mm) - Square.
  • Signature: Aspect ratio 3:1 (e.g., 600x200 pixels).
  • Format: JPEG/JPG only (HEIC not allowed).
  • File Size: Between 10 KB and 500 KB.

Resolving the 3:1 Signature Ratio

One of the most common reasons for OCI application rejection is the signature ratio. The portal requires a 3:1 aspect ratio. Our converter allows you to crop and scale your signature to these exact proportions without losing clarity.

OCI Application FAQ

Why does the OCI portal say "Invalid File Size"?

The OCI portal is very strict. If your photo is too small (under 10KB) or too large (over 500KB), it will fail. Our tool uses binary search compression to find the perfect quality that stays within this window.

Can I take the OCI photo at home?

Yes! With a plain white background and good lighting, you can take a photo on your iPhone. Use our tool to convert it to the required 2x2 inch JPG format.
