Document Photo Size Guide: Aadhaar, PAN, Passport, Visa & Exam Photos
Every common Indian document photo specification in one place — so you stop guessing dimensions and file-size limits application by application.
Almost every Indian government or institutional form — Aadhaar updates, PAN applications, passport renewals, visa forms, competitive exams, even bank KYC — asks for a photo in its own exact size and file-size limit. Get it wrong, and the portal either rejects the upload outright or silently stretches your photo into something that looks noticeably off. This guide puts every common specification in one place, so you can check the number once instead of hunting through five different application help pages.

File-size caps for Aadhaar, PAN, and passport portals change more often than the pixel dimensions do, and vary by which specific form or update request you're filing — always confirm the current limit stated on your form before submitting.
Why Does Every Form Want a Different Size?
Each document serves a different purpose, and the photo requirement reflects that. Passport and visa photos follow international biometric standards designed for automated facial recognition at border checkpoints, which is why face-framing (roughly 70-80% of the frame) matters so precisely for those two. Aadhaar and PAN photos are sized for small printed ID cards, so the dimensions are driven by physical card layout rather than biometric matching. Exam and signature specs are the strictest on file size, not dimensions — they exist so application portals handling thousands of simultaneous uploads on deadline day don't buckle under the load.
How to Prepare Any of These, Step by Step
- Take a photo against a plain, light-colored background with even, shadow-free lighting.
- Face the camera directly with a neutral expression — most of these specs require both eyes open, mouth closed.
- Open the specific tool for your document from the chart above and upload your photo.
- Adjust the crop so your face is framed correctly for that document's guideline.
- If there's a file-size limit, check the result against it — run it through the Image Compressor if it's still too large.
- Download and upload to your application portal.
Mistakes That Get Applications Rejected
- Using one photo for every document — a passport-cropped photo uploaded to an Aadhaar form (or vice versa) often gets stretched or rejected, since the aspect ratios differ.
- Ignoring the file-size cap — exam and signature portals in particular reject files above their stated KB limit outright, even if the pixel dimensions are correct.
- Smiling where a neutral expression is required — passport and visa photos specifically ask for neutral expression, not a smile.
- An outdated photo — passport and visa photos should typically be recent, closely resembling your current appearance.
- Wrong background color — most of these specs call for a plain, light background; a busy or dark background is a common rejection reason.
Frequently Asked Questions
Can I use the same photo for Aadhaar and PAN applications?
The aspect ratios are close but not identical (3.5×4.5cm vs 2.5×3.5cm), so it's best to crop each one separately using its specific tool rather than reusing one crop for both.
Do these tools upload my photo to a server?
No — every tool listed here crops and resizes entirely inside your browser using the Canvas API. Your photo is never uploaded anywhere.
My exam portal has a different KB limit than listed here — what do I do?
Always follow the specific limit stated on your application form. The ranges here are common defaults, not universal rules — run the result through the Image Compressor if it's still above your form's stated cap.
Is a scanned signature accepted, or does it need to be handwritten digitally?
A scanned or photographed signature on plain paper is standard and accepted by most forms — crop and resize it the same way as a digitally drawn one.
What if my photo doesn't meet the face-coverage guideline after cropping?
Retake the photo standing a bit closer to the camera, then re-crop — cropping alone can't add detail the original photo didn't capture at the right distance.
