Every Indian government exam portal has its own photo, signature, and document upload specifications — and they differ enough that a photo accepted by NTA NEET will be rejected by the SSC OTRP portal. This page consolidates the exact requirements for every major exam into one reference you can bookmark and share.
How to use this guide: Find your exam in the relevant section. Check the Photo Size, Signature Size, Dimensions, and Format columns. Use the linked tools in each section to compress or resize in one click. Always verify against the official notification for your exam cycle — requirements can change each year.
SSC Exams (Staff Selection Commission)
SSC uses the OTRP (One Time Registration Portal) at ssc.gov.in. The portal validates file size server-side — files outside the allowed range are rejected immediately before any other check. All SSC exams require JPG/JPEG format only.
| Exam | Photo Size | Signature Size | Dimensions | Format |
|---|---|---|---|---|
| SSC CGL (Combined Graduate Level) | 20–50 KB | 10–20 KB | ~200×230 px | JPG |
| SSC CHSL (Combined Higher Secondary) | 20–50 KB | 10–20 KB | ~200×230 px | JPG |
| SSC MTS (Multi Tasking Staff) | 20–50 KB | 10–20 KB | Passport size | JPG |
| SSC GD Constable | 10–20 KB | 10–20 KB | Passport size | JPG |
| SSC CPO (Central Police Organisation) | 20–50 KB | 10–20 KB | Passport size | JPG |
| SSC JE (Junior Engineer) | 20–50 KB | 10–20 KB | Passport size | JPG |
| SSC Steno (Grade C & D) | 20–50 KB | 10–20 KB | Passport size | JPG |
SSC photo rules: Plain white or light background. Full face visible. No glasses (increasingly enforced from 2024 cycle). Colour photograph taken within 6 months. No cap or headgear unless required for religious reasons. Signature must be on plain white paper with dark blue or black ballpoint pen — no lined paper, no gel pens.

IBPS and Banking Exams
IBPS (Institute of Banking Personnel Selection) runs the PO, Clerk, RRB, and SO exams for public sector banks. SBI and RBI conduct their exams independently but follow similar specifications. IBPS portals specifically require 200×230 pixels for photos — one of the few portals that enforces an exact pixel dimension alongside the KB limit.
| Exam | Photo Size | Signature Size | Dimensions | Format |
|---|---|---|---|---|
| IBPS PO (Probationary Officer) | 20–50 KB | 10–20 KB | 200×230 px | JPG |
| IBPS Clerk | 20–50 KB | 10–20 KB | 200×230 px | JPG |
| IBPS RRB PO / Clerk | 20–50 KB | 10–20 KB | 200×230 px | JPG |
| IBPS SO (Specialist Officer) | 20–50 KB | 10–20 KB | 200×230 px | JPG |
| SBI PO | 20–50 KB | 10–20 KB | 200×230 px | JPG |
| SBI Clerk | 20–50 KB | 10–20 KB | 200×230 px | JPG |
| RBI Grade B | 20–50 KB | 10–20 KB | 200×230 px | JPG |
| RBI Assistant | 20–50 KB | 10–20 KB | 200×230 px | JPG |
IBPS/SBI photo rules: Light (preferably white) background. Face must occupy at least 70% of the frame. No dark glasses. Photograph taken within 3 months. Name and date may be printed at the bottom of the photograph — optional but recommended for document verification. IBPS is strict about the 200×230 px requirement — resize before compressing.

NTA Exams (National Testing Agency)
NTA runs NEET UG, JEE Main, CUET, UGC NET, and several other national exams. NTA portals are the most lenient on file size — they allow up to 200KB for photos. This means you can upload a significantly sharper, clearer photo than SSC or IBPS portals allow. Always target close to the maximum for NTA exams — a 150KB photo looks dramatically better than a 20KB one.
| Exam | Photo Size | Signature Size | Dimensions | Format |
|---|---|---|---|---|
| NEET UG | 10–200 KB | 4–30 KB | 3.5×4.5 cm | JPG |
| JEE Main | 10–200 KB | 4–30 KB | 3.5×4.5 cm | JPG |
| CUET UG / PG | 10–200 KB | 4–30 KB | 3.5×4.5 cm | JPG |
| UGC NET | 4–200 KB | 4–30 KB | 3.5×4.5 cm | JPG |
| CMAT / GPAT / CSIR NET | 10–200 KB | 4–30 KB | 3.5×4.5 cm | JPG |
NTA photo rules: White background only. Clear face, full front view. Photo must be recent (within 6 months). Name and date of photograph must appear printed or handwritten at the bottom — NTA is strict about this; missing labels cause problems at exam centre entry during identity verification. Scanned photographs are not accepted — use a digital photo.

UPSC Exams
UPSC (Union Public Service Commission) exams — Civil Services (IAS, IPS, IFS), CAPF, CDS, NDA, and ESE — are more lenient on file size than SSC or IBPS. The DAF (Detailed Application Form) for Civil Services also requires scanned copies of degree certificates, marksheets, caste certificates, and other supporting documents, each within the size limit.
| Exam | Photo Size | Signature Size | Document Scans | Format |
|---|---|---|---|---|
| UPSC Civil Services (IAS / IPS / IFS) | up to 300 KB | up to 300 KB | up to 300 KB each | JPG |
| UPSC CAPF (AC) | up to 100 KB | up to 100 KB | up to 100 KB | JPG |
| UPSC CDS | up to 100 KB | up to 100 KB | up to 100 KB | JPG |
| UPSC NDA / NA | up to 100 KB | up to 100 KB | up to 100 KB | JPG |
| UPSC ESE / IES | up to 100 KB | up to 100 KB | up to 100 KB | JPG |
UPSC photo rules: Passport-size photograph with plain white background. Recent photo within 3 months for DAF. Name printed at bottom. For the Civil Services DAF, each document scan (degree, marksheet, caste certificate, etc.) must be a JPG under the allowed KB — use the PDF to JPG converter to convert PDF documents before uploading.

Railway Exams (RRB)
Railway Recruitment Board exams attract 10–30 million applicants per cycle — the highest volume of any Indian exam category. RRB portals follow SSC-like specifications and face the same high-traffic congestion during registration windows. Pre-compressing your photo before opening the form is especially important for RRB applications.
| Exam | Photo Size | Signature Size | Dimensions | Format |
|---|---|---|---|---|
| RRB NTPC (Non-Technical Popular Category) | 20–50 KB | 10–40 KB | Passport size | JPG |
| RRB Group D | 20–50 KB | 10–40 KB | Passport size | JPG |
| RRB JE (Junior Engineer) | 20–50 KB | 10–40 KB | Passport size | JPG |
| RRB ALP (Assistant Loco Pilot) | 20–50 KB | 10–40 KB | Passport size | JPG |
| RPF / RPSF Constable | 20–50 KB | 10–40 KB | Passport size | JPG |

Passport and Visa Applications
Passport Seva (passportindia.gov.in) and visa applications follow the ICAO international standard for passport photographs. Unlike exam portals, passport photos must meet strict dimensional and print quality rules — the photo is physically examined by an officer.
| Application | Dimensions | File Size | Background | Format |
|---|---|---|---|---|
| Indian Passport (Passport Seva) | 35×45 mm | up to 1 MB | White only | JPG |
| Schengen Visa (Europe) | 35×45 mm | under 500 KB | White or light grey | JPG |
| US Visa (B1/B2/F1) | 51×51 mm (2×2 inch) | under 240 KB | White only | JPG |
| UK Visa | 35×45 mm | under 6 MB | Cream or light grey | JPG |
| Canada Visa | 35×45 mm | under 4 MB | White only | JPG |
| OCI Card | 35×45 mm | under 1 MB | White only | JPG |

State PSC Exams
State Public Service Commission exams each manage their own portals with independent specifications. Most follow SSC-like format but with varying KB limits. The table below reflects typical requirements — always read the specific notification PDF for your exam cycle, as state PSC requirements change more frequently than central government exams.
| State PSC | Photo Size | Signature Size | Format |
|---|---|---|---|
| TNPSC (Tamil Nadu) | 20–60 KB | 10–30 KB | JPG |
| UPPSC (Uttar Pradesh) | up to 50 KB | up to 30 KB | JPG |
| MPSC (Maharashtra) | 20–200 KB | 10–100 KB | JPG |

Rules That Apply to Every Indian Exam Portal
Regardless of which exam you are applying for, these rules hold universally:
- Use JPEG/JPG format only. PNG and HEIC files are rejected by almost every portal. iPhone users: convert HEIC to JPG first using the HEIC to JPG converter before compressing.
- Start from the original camera photo. Never use a WhatsApp-forwarded photo, a screenshot, or a photo of a printed photo. Every compression cycle degrades quality — compress once from the original.
- Target the maximum allowed KB, not the minimum. If the portal allows 20–50KB, target 48KB. The extra kilobytes are visible face clarity, which matters to human reviewers at document verification.
- Plain white or very light background. No patterns, no colours, no gradients. A plain white wall works. Dark or patterned backgrounds cause rejection at DV even when the portal upload passes.
- Recent photograph. Most portals require photos taken within 3–6 months. Old photos cause rejection at in-person document verification even if the portal upload passes.
- No glasses. Increasingly enforced across all portals from 2024 onwards — check the specific notification for your exam.
- Full face clearly visible. No hair covering the forehead, no shadow across one side, no chin or top of head cropped out.
- Fill the form before uploading. Portal session timeouts during slow uploads cause loss of entered data. Pre-compress your photo and signature before opening the form. A 48KB JPG uploads in under 2 seconds even on slow mobile data.

Frequently Asked Questions
Which exam has the strictest photo size limit in India?
SSC GD Constable has the tightest limit — photos must be between 10KB and 20KB. Most other SSC exams allow 20–50KB. NTA exams (NEET, JEE, CUET) are the most lenient at 10–200KB — use that range to upload the sharpest possible photo.
Can I use the same compressed photo for multiple exams?
Yes, if the same file meets each portal's KB range and pixel dimension requirements. A 200×230 pixel, 48KB JPG will pass SSC, IBPS, SBI, and RRB portals without any changes. For NTA portals you can use the same photo — it falls well within the 10–200KB range. For IBPS specifically, the 200×230 pixel dimension is checked, so resize first if reusing a photo from a different source.
What is the correct photo size in pixels for Indian exam forms?
For IBPS, SBI, and RBI: exactly 200×230 pixels (width × height). For SSC and RRB: passport-size, typically around 200×230 pixels, though the portal usually accepts any passport crop as long as the KB is correct. For NTA (NEET, JEE, CUET): 3.5×4.5 cm at 100 DPI = approximately 138×177 pixels, though NTA accepts larger images.
What happens if my photo passes the portal but is rejected at Document Verification?
Document Verification (DV) is a manual check. Staff compare your appearance against the photo and check visual quality rules: background colour, recency, face clarity, and absence of glasses. A blurry 20KB photo that passed the portal upload may be rejected at DV. Always target the maximum allowed KB — a 48KB photo is noticeably clearer than a 20KB one when viewed by a human reviewer.
Do I need a separate signature upload for every exam?
Yes — each exam portal requires a separate signature upload alongside the photo. Use the Signature Resizer which is preset for the 10–20KB range used by SSC, IBPS, SBI, UPSC, and RRB. Sign on plain white paper with a dark ballpoint pen, photograph or scan it, then run through the resizer.
My portal only accepts JPG but my phone takes HEIC photos — what do I do?
iPhone cameras save photos in HEIC format by default. Use the free HEIC to JPG converter on PhotoSizeTool — it converts in your browser, nothing is uploaded. Then compress the resulting JPG to your target KB using any of the tools above.
