Before you resize anything for RRB NTPC, know this: the portal does not want a photo file. It takes your photograph live, through a webcam or by handing you a QR code to open on your phone, and matches it against Aadhaar. There is nothing to upload and nothing to prepare.
That is from the current notification, CEN 07/2025, read on 7 September 2026. Around fourteen sites publish requirements for exams like this one, and they still carry photo dimensions for RRB. Those figures belong to a cycle that has ended, and following them costs you an afternoon spent making a file the portal will never ask for.
A dimension for a form that no longer takes a file is not a small error.
UPSC captures live too, and we could not verify the rest
A UPSC advertisement confirms live photo capture as well, so there is no photograph to upload there either. Its signature figures we could not confirm: the page carrying them refuses automated requests, and the numbers quoted elsewhere could not be traced to any UPSC document. So UPSC sits on our registry as unverified, with the reason written out, rather than filled in with whatever the aggregators agree on.
NEET and JEE specify a size and no dimensions at all
NTA's bulletins for NEET (UG) 2026 and JEE (Main) 2026 ask for a JPG photograph of 10 to 200 KB and a signature of 10 to 100 KB. The photo wants a white background for NEET, white or light for JEE, with the face filling about 80% of the frame, ears visible and no mask. There is no pixel requirement and no centimetre requirement in either bulletin.
Which means an exact pixel figure published for NEET was invented, or copied from someone who invented it. Where the document is silent, the useful answer is that the document is silent — not a number that looks precise.
Both also take a live capture at the portal: NEET matches it against Aadhaar, and JEE does it by webcam or a QR handoff to your phone. NEET additionally asks you to bring 6 to 8 passport-size and 4 to 6 postcard-size prints of the same photograph to the centre, which is the requirement people find out about last.
The six exams, as their own documents state them
| Exam | Photo | Signature |
|---|---|---|
| RRB NTPC (UG), CEN 07/2025 | No file — captured live | 30–49 KB · 35 × 20 mm · at least 140 × 60 px · 100 dpi |
| NEET (UG) 2026 | 10–200 KB · no dimension given | 10–100 KB · no dimension given |
| JEE (Main) 2026 | 10–200 KB · no dimension given | 10–100 KB · no dimension given |
| GATE 2026 | 5–600 KB · 35 × 45 mm · 200 × 260 to 530 × 690 px | 3–300 KB · 250 × 80 to 580 × 180 px |
| IBPS PO / MT 2026 | 20–50 KB · 200 × 230 px | 10–20 KB · 140 × 60 px |
| SSC CGL 2026 | No size or dimension found in the notice | 10–20 KB · 60 × 20 mm |
All six want JPG. A few carry rules that reject a technically correct file: GATE wants the face filling 60 to 70% of the frame and the signature between 1:2.75 and 1:3.75 in ratio; RRB wants running handwriting in black or blue and treats block capitals as grounds for rejection; IBPS allows no cap, hat or dark glasses, and takes a live capture that it matches against your upload.
SSC states the signature and barely mentions the photograph
The SSC CGL notice is precise about the signature — 10 to 20 KB, 60 × 20 mm — and says only that the photograph must be recent and in colour. We could not find a photo dimension in it, so none is listed. That may well mean SSC does not set one. It also says candidates using Aadhaar-based authentication are exempt from rejection on photo or signature grounds, which is the most useful line in the document and the one no aggregator quotes.
Where each figure came from
| Exam | Source | Checked |
|---|---|---|
| RRB NTPC | rrbajmer.gov.in | 7 Sep 2026 |
| NEET (UG) | neet.nta.nic.in | 7 Sep 2026 |
| JEE (Main) | jeemain.nta.nic.in | 7 Sep 2026 |
| GATE | gate2026.iitg.ac.in | 7 Sep 2026 |
| IBPS PO / MT | ibpsreg.ibps.in | 7 Sep 2026 |
| SSC CGL | ssc.gov.in | 7 Sep 2026 |
Four of the six were read directly from the official document. Two — IBPS PO and SSC CGL — came off the official domain without every figure being byte-verified, and they are marked that way on the page rather than presented as equal to the rest. A date matters as much as a number here: requirements move with each notification cycle, so a figure with no date is a figure you cannot rely on, including ours once it ages.
Two exams are missing on purpose
UPSC, for the reason above. And CTET: the official bulletin is on ctet.nic.in but its text could not be extracted, and the figures other sites publish for it come from aggregators rather than from that bulletin. Both are listed on the page with the reason, because someone arriving for CTET deserves to know we could not confirm the numbers rather than assume we forgot the exam.
Six entries with a link beat fourteen without one. The site that publishes the most exams is the site that has copied the most from other people who copied.
Once you know the number
Knowing you need 20 to 50 KB does not produce a 20 to 50 KB file, which is the part the registry links out for: compressing to an exact kilobyte target, setting dimensions, or cropping to the right shape. Those run on your device, and for these two files in particular — a photograph of your face and your signature — that is not a detail.
And check the notification yourself before you upload. Ours points at it for exactly that reason: a summary's job is to send you to the source, not to replace it.
