About RPF Recruitment
The Railway Protection Force (RPF) is the security wing of Indian Railways, responsible for the protection of railway property, passenger areas, and passengers. RPF Sub-Inspector (SI) and Constable recruitment is conducted through the RRB (Railway Recruitment Board) portal, and follows a spec sheet very similar to the one used for RRB Group D.
Because RPF recruitment runs through the same underlying RRB application infrastructure, candidates who have previously applied for RRB Group D or RRB NTPC will find the upload process and validation rules familiar.

RPF SI and Constable recruitment doesn't end with the written test and a portal upload — it includes a Physical Efficiency Test (PET) and Physical Measurement Test (PMT), where you're checked in person for a police/force role, not a desk posting. That in-person stage is where a photo that doesn't actually look like you becomes a real problem, not just a formatting error.
Do's
- Take the photo against a plain white or light blue background
- Face the camera directly, both ears visible, no side angles — this is the photo PET/PMT officials will hold up against you in person
- Wear formal or semi-formal clothing — no sleeveless tops
- Ensure adequate, even lighting — no harsh shadows on your face
- Keep a neutral, natural expression with mouth closed
- Ensure the photo is in focus and not blurry
Don'ts
- Do not wear sunglasses or tinted glasses
- Do not wear a cap, hat, or headgear (exceptions for religious reasons)
- Do not use a heavily edited or filtered photo — PET/PMT staff will be matching your face against it on the ground, not just scanning a file
- Do not use a photo older than 3 months
- Do not reuse a scanned copy of an old ID card photo
- Do not crop someone else out of a group photo
Because RPF SI/Constable is a physically-verified force role, candidates who clear the written stage go on to PET and PMT, where officials check your identity against your uploaded photo and admit card in person, not through a portal. Candidates who apply for both RPF and RRB Group D in the same cycle sometimes upload the wrong exam's saved photo since both use near-identical dimensions — with an in-person physical stage ahead, it's worth confirming you've submitted the right file for this specific application before final submission.
How to Resize Your Photo to RPF Specifications
Open the resizer with RPF's specifications already pre-loaded — upload your photo, crop it if needed, and download once the Form Readiness panel turns green. Since PET/PMT involves in-person verification, keep the photo genuinely representative of how you currently look. For a full walkthrough of the tool, see our step-by-step resizing guide.
What Pixel Dimensions Should the RPF Photo Be?
The RPF notification specifies the dimensions in millimetres (35mm × 45mm), but photo portals work in pixels. The equivalent pixel dimensions depend on the resolution (DPI) used:
| Resolution | Pixel Width | Pixel Height |
|---|---|---|
| 96 DPI (standard screen) | 132 px | 170 px |
| 150 DPI (medium print) | 207 px | 266 px |
| 300 DPI (high quality print) | 413 px | 531 px |
Our tool uses 96 DPI by default, which is standard for web uploads. SarkariKagaz.pro automatically outputs the correct pixel dimensions for the RPF preset, so you never need to calculate this yourself.
RPF Recruitment 2026 — Other Important Notes
- Keep the same photo on file from CBT all the way through PET/PMT — officials at the physical stage check your face against it in person, so a mismatch stands out far more here than in a purely online process
- Bring printed copies of this same photo to the examination centre
- The RRB/RPF portal may validate your photo automatically — if it fails, the error will appear immediately after upload
- Always download and save your resized photo in a clearly named folder before going to fill the form
Exam specifications may change with each new notification. Always cross-check with the latest official RPF notification on rpf.indianrailways.gov.in or the official RRB site before submitting your application.
