Resize & compress your photo and signature to exact Railway Recruitment Board specifications. Free, instant & 100% private — works for all 21 RRB zones.
The Railway Recruitment Board Assistant Loco Pilot (RRB ALP) examination is one of India's most popular government job exams. Conducted by the 21 Regional Railway Recruitment Boards (RRBs) across India under the Ministry of Railways, the ALP exam recruits candidates for the post of Assistant Loco Pilot — the person who assists the Loco Pilot (train driver) in operating trains on the Indian Railways network. With over 5 crore applications received in previous cycles, RRB ALP is among the most competitively applied-for government positions in India.
The RRB online application portal has strict automated validation for photo and signature uploads. Every year, thousands of candidates face rejection or delays because their photo or signature doesn't meet the exact technical specifications. Our RRB ALP Photo Resizer Tool is pre-configured with the correct Railway Recruitment Board specifications — just upload and download.

💡 Always verify: Download the latest RRB ALP 2026 official notification and CEN (Centralised Employment Notice) from your regional RRB website before submitting. Photo specs are confirmed in the official notification PDF.
India has 21 Railway Recruitment Boards (RRBs), each responsible for recruitment within a specific geographic zone of the Indian Railways network. While all RRBs follow the same centralized photo specifications issued by the Railway Recruitment Control Board (RRCB), the online application portals are operated independently by each RRB. Our tool works for every RRB portal across all zones.
All 21 RRBs follow the same centralized photo specifications issued by the Ministry of Railways through the official CEN (Centralised Employment Notice). The standard is: photo 200×230 pixels, JPEG, 20–50 KB; signature 140×60 pixels, JPEG, 10–40 KB. These specifications are consistent across RRB Patna, RRB Kolkata, RRB Mumbai, RRB Chennai, and every other zone.
However, the user interface and validation messages of individual RRB portals may vary slightly. Some older RRB portals may not display a clear error message when a file is the wrong size — the form simply doesn't proceed. This is why using a pre-configured tool like ours eliminates all guesswork.
ℹ️ Note: If your regional RRB portal shows a different file size range (for example, some zones occasionally accept up to 100 KB), use our Custom Settings option to adjust the maximum KB value accordingly while keeping the 200×230 pixel dimensions.
Understanding the RRB ALP exam structure helps you plan not just the photo upload, but your entire application and preparation strategy. Here is everything you need to know about the RRB ALP 2026 examination:
The Assistant Loco Pilot (ALP) is a Group C non-gazetted post in the Indian Railways, working directly under the Loco Pilot (LP) to operate train engines. It is one of the most technically demanding and responsible roles in the railway system. ALPs are responsible for:
After serving as ALP for a prescribed period (typically 3–5 years with good performance), candidates can be promoted to Loco Pilot (Goods), then Loco Pilot (Mail/Express), and eventually Senior Loco Pilot — one of the highest-paid non-gazetted positions in Indian Railways.

Previous RRB ALP recruitment cycles have announced vacancy counts ranging from 26,000 to over 64,000 posts. In the CEN 01/2018 cycle, 26,502 vacancies were notified and over 2.67 crore applications were received. The RRB ALP 2024–25 cycle is expected to notify a similar or higher number of vacancies given the ongoing expansion of the Indian Railways under various infrastructure projects including the Vande Bharat train program, dedicated freight corridors, and metro/suburban rail expansion.
| Parameter | ALP (Assistant Loco Pilot) | Technician Grade III |
|---|---|---|
| Nature of Work | Train operation (driving support) | Technical maintenance (workshops, depots) |
| Stage 2 Part B | Yes — mandatory trade test | Yes — trade-specific |
| CBAT | Yes — aptitude test required | No CBAT |
| Night Duty | Yes — round the clock shifts | Shift-based, less frequent nights |
| Travel | Extensive — often away from home base | Based at workshop/depot |
| Career Path | ALP → LP (Goods) → LP (Mail) → Senior LP | Tech Grade III → Tech Grade II → JE → SSE |

✅ Career tip: If you qualify for both ALP and Technician from the same exam, choosing ALP offers a clearer and faster promotion track to the coveted Loco Pilot (Mail/Express) position, which comes with significantly higher allowances and prestige.
The RRB portal for ALP applications performs both automated and manual photo validation. Automated checks verify file size and dimensions. Manual review by Railway officials verifies photo quality, background, and whether the face is clearly visible. Here is the complete guide to what is and is not acceptable:
RRB ALP has one of the most stringent medical fitness standards among all government exams because it involves train operation. Candidates are required to pass a Railway Medical Examination at the time of document verification and joining. The photo submitted in your application is your first point of identity verification — it must be a clear, accurate, recent representation of your appearance.
Candidates with spectacles should note that Railway medical standards for ALP require normal distant vision without glasses (6/6 in each eye) or with glasses within certain limits. If you wear glasses daily, discuss with a railway medical officer about implications. For the application photo, spectacles are generally allowed if you wear them regularly and there is no glare or reflection.
The 200×230 pixel dimension for RRB ALP photos corresponds to a portrait-orientation passport-size image at standard web/screen resolution (96–100 DPI). At this resolution, a 200×230 pixel image prints at approximately 2.08 inches × 2.4 inches — slightly larger than the standard Indian passport photo (2×2 inches) but within the acceptable range for railway records.
When our tool resizes your photo to 200×230 pixels, it uses a "cover fit" algorithm that scales and crops your original photo to exactly fill this canvas. The crop is centred, ensuring your face remains in the middle of the frame. A white background is applied automatically, so even if your original photo has a slightly off-white background, the output will have a clean white background.
Every RRB ALP application requires both a passport-size photograph and a signature upload. The signature serves as a legally binding identity marker — it is used during examination hall attendance, document verification, and employment joining formalities. Getting the signature right during the application phase is crucial.
| Parameter | Required Value |
|---|---|
| File Format | JPEG / JPG |
| Dimensions (pixels) | 140 × 60 pixels |
| Minimum File Size | 10 KB |
| Maximum File Size | 40 KB |
| Background | Plain white paper |
| Ink Colour | Black or dark blue ballpoint pen |
| Script | Running/cursive handwriting — NOT block capitals |
| Size on Paper | Natural writing size — not too cramped or too large |
The RRB ALP selection process spans multiple stages over several months or sometimes over a year: CBT Stage 1, CBT Stage 2, CBAT (for ALP candidates), Document Verification, and Medical Examination. At every single stage where attendance sheets are maintained, you will be asked to sign. These signatures are compared against the application form signature. Inconsistency — even minor variations — can trigger additional scrutiny.
During Document Verification, Railway officials specifically verify that your live signature matches the uploaded signature. During medical examination and joining formalities, your ID documents must match your RRB application data including the photo.
The bottom line: decide on your signature style before the RRB ALP application and practice it until it becomes automatic. Use this same signature on every document from this point forward.
⚠️ Important: Never sign in capital letters for any Indian government exam application. The RRB ALP notification explicitly states signatures must be in running handwriting. Capital letter signatures are treated as incomplete or invalid and can lead to application rejection during document verification.
The RRB ALP online application process is managed through individual RRB regional websites. While the interface may vary slightly between zones, the core process follows a standardized flow defined by the Railway Recruitment Control Board. Here is a complete walkthrough of the application process with special focus on the photo and signature upload steps:
| Category | Application Fee | Refund After CBT 1 |
|---|---|---|
| UR / OBC / EWS (Male) | ₹500 | ₹400 refunded |
| SC / ST | ₹250 | ₹250 refunded (full) |
| Ex-Servicemen | ₹250 | ₹250 refunded (full) |
| Persons with Disability (PwD) | ₹250 | ₹250 refunded (full) |
| Women (all categories) | ₹250 | ₹250 refunded (full) |
| Transgender (all categories) | ₹250 | ₹250 refunded (full) |
| Minorities / EBC | ₹250 | ₹250 refunded (full) |
💡 Smart tip: Prepare your photo and signature files at least 2–3 days before the registration deadline. RRB portals receive millions of simultaneous users in the last 48 hours and frequently slow down or crash. Having your files ready lets you submit quickly even on a slow connection.
During peak registration periods, the RRB helpdesk and online forums are flooded with questions about photo upload errors. Here is a comprehensive troubleshooting guide for every issue you might face:
What happened: Your photo file is larger than 50 KB. This is the most common error. A standard phone camera produces photos of 3–8 MB — 60 to 160 times larger than the RRB limit.
Fix: Use our RRB ALP Photo Resizer. It automatically compresses to within 20–50 KB. Alternatively, use our Compress to 50KB tool. Both produce RRB-compliant output instantly.
What happened: The file is smaller than the minimum 20 KB. This happens when the original image is very low resolution or has already been heavily compressed.
Fix: Start with a higher resolution original photo. Our tool is designed to stay within the 20–50 KB range. If the output is consistently under 20 KB, your original photo has too little detail — take a new photo with a better camera.
What happened: Your photo is not 200 pixels wide and 230 pixels tall. This happens if you manually resized in Microsoft Paint, edited in your phone gallery app, or used a generic online resizer that didn't hit the exact pixel counts.
Fix: Our RRB ALP Photo Resizer produces exactly 200×230 pixels every time. Don't rely on manual resizing tools that approximate dimensions.
What happened: Your image is in PNG, HEIC, WebP, or BMP format. iPhone users frequently hit this error because iPhones save as HEIC by default. Screenshots are usually PNG.
Fix: For iPhone photos — use our HEIC to JPG Converter. For any other format — upload directly to our RRB ALP Photo Resizer (it accepts PNG and WebP and converts to JPEG automatically during processing).
What happened: A Railway official has manually flagged your photo during form verification because the background is not white. Blue studio backgrounds, outdoor backgrounds, or colored walls are not acceptable.
Fix: Take a new photo against a plain white wall, white chart paper, or white bedsheet. This is the only reliable fix. Wait for the correction window (if open) and re-upload. Our tool cannot replace the background — always take the photo with the correct background.
What happened: The original photo was blurry, taken in poor light, or was a very low resolution image that became pixelated when expanded.
Fix: Take a fresh photo in good lighting with your phone camera set to highest resolution. Use our Image Quality Enhancer to slightly improve sharpness before resizing, then use the RRB ALP Photo Resizer.
What happened: Signature file does not meet the 140×60 pixel / 10–40 KB requirement.
Fix: Select "Signature" in our tool's Document Type selector and upload your cropped signature image. The tool automatically resizes to 140×60 pixels and compresses to within 10–40 KB.
⚠️ RRB Portal Timeout Warning: RRB application portals have session timeouts of 15–20 minutes. If you spend too long searching for your files mid-application, the session may expire and you'll lose your progress. Always have your photo, signature, and all document files prepared and easily accessible before you begin the application.
While getting your photo right is the first step, your long-term success in RRB ALP depends on thorough exam preparation. Here is a structured guide to the entire selection process:
CBT Stage 1 is a screening test with 75 questions to be answered in 60 minutes. There is negative marking (1/3 mark per wrong answer). The syllabus includes:
ℹ️ CBT Stage 1 Qualifying: Only the top candidates from Stage 1 (typically 15× the number of vacancies) are called for Stage 2. Your CBT Stage 1 marks are NOT counted in the final merit list — it is only a screening exam.
CBT Stage 2 has two parts and is the most important stage for final selection:
The final merit list is based on normalized CBT Stage 2 Part A marks only. Part B is pass/fail with a 35% threshold. Higher Part A marks = better rank = better choice of division/zone during document verification.
Candidates who qualify CBT Stage 2 and opt for the ALP post (not Technician) must appear for the CBAT — a unique test that assesses psychological aptitude for train operation. It consists of:
The CBAT is qualifying in nature — you must clear it with a minimum T-score in each battery. Those who fail CBAT are considered only for Technician posts (if they also qualified Stage 2). CBAT cannot be prepared for in the traditional sense — it tests innate cognitive abilities. However, practice on attention and memory exercises over the months leading up to the exam can improve performance.
Candidates who clear all CBT stages (and CBAT for ALP) are called for Document Verification followed by a Railway Medical Examination. The documents required include:
💡 Photo continuity: At Document Verification, you are asked to bring the same photo that you uploaded during registration. Keep digital copies of your RRB ALP application photo saved on your phone and cloud storage. Print several copies well before the DV date.
RRB ALP has some of the most stringent medical requirements of any government exam because it involves train operation. Key medical standards include:
| Medical Parameter | ALP Requirement |
|---|---|
| Distant Vision (Unaided) | 6/6 in each eye (or 6/9 with glasses allowed in some cases) |
| Near Vision | Sn: 0.6 in each eye (with or without glasses) |
| Colour Vision | Must pass Ishihara Colour Vision Test — no colour blindness |
| Field of Vision | Normal full field in both eyes |
| Night Vision | Must pass night vision test (Mesopter test) |
| Hearing | Must hear a forced whispered voice at 3 metres with each ear |
| Binocular Vision | Required — both eyes must work together |
When uploading a personal photograph to any online tool, data privacy is a legitimate concern. Passport-size photos linked to government exam applications are sensitive documents. At ExamPhotoResize.in, we have built the tool with a fundamental privacy principle: your photo never leaves your device.
When you "upload" a photo to our RRB ALP Photo Resizer, what actually happens is this: the JavaScript code running in your browser tab reads the image from your device's local memory. It draws the image onto an HTML5 Canvas at 200×230 pixels, applies JPEG compression until the file size falls between 20–50 KB, and then makes the resulting file available as a download link — all within your browser's memory. At no point is any data transmitted to any server.
We don't ask for your name, email, phone number, Aadhaar number, or any personal information. There is no account creation and no tracking of individual usage. Standard anonymous web analytics (page visits and tool popularity) are collected but contain no personal data or image information whatsoever.
✅ Verification: Open our tool, then turn on airplane mode (disconnect from internet), and then try uploading and resizing a photo. It works perfectly — proving that no internet connection (and therefore no server) is involved in the image processing.
