The Railway Recruitment Board (RRB) Assistant Loco Pilot (ALP) examination attracts millions of applicants seeking technical roles within the Indian Railways. Because the ALP role requires stringent medical and vision standards, the application portal uses extremely rigid automated document verification software to screen uploaded files. If your RRB ALP photo size, dimensions, or signature format do not perfectly match the official guidelines, your upload will be immediately rejected. Using a specialized resizer guarantees your application passes the initial screening without any errors.
The official RRB notification outlines precise guidelines for your passport-size color photograph. The required physical dimension is 35mm x 45mm. When utilizing a digital resizer, this maps directly to 320 pixels wide by 240 pixels high (320x240 px). Additionally, the file size must be strictly compressed to fall between 20 KB and 50 KB. Images over 50 KB simply cannot be uploaded to the RRB portal.
Because vision is critical for the Assistant Loco Pilot role, your photograph is heavily scrutinized. It should be taken against a plain white or a very light-colored background. You must not wear any spectacles, tinted glasses, or sunglasses in your photograph—even if you wear prescription glasses normally. Wearing caps or hats is also strictly forbidden. The exam invigilators rely on these photographs during the computer-based test (CBT) and the intense medical verification rounds.
Your signature acts as a crucial biometric verification. When you resize your signature for the RRB ALP exam, it must be exactly scaled to 50mm x 20mm. Digitally, this means the signature resolution should be 140 pixels wide by 60 pixels high (140x60 px). The signature file must be compressed into a smaller range, maintaining a file size between 10 KB and 40 KB. You must sign on plain white paper using a dark blue or black ink pen.
An extremely important railway rule: you must not sign in uppercase block letters. Signatures featuring all capital letters are deemed legally invalid and will cause the immediate disqualification of your ALP application.
In various RRB recruitment cycles, candidates have been instructed to display their printed name and the date of capturing the photograph directly on the image itself. While you should confirm this with your specific RRB zone notification, our tool makes compliance effortless. By enabling the "Add Name & Date" switch, you can input your details. The resizer algorithm will automatically overlay a clean black slate with white text at the bottom of your successfully compressed 50 KB photo.
Figuring out how to translate millimeter measurements to pixels, while also attempting to compress a high-resolution phone image down to exactly 50 KB, is notoriously difficult on standard photo apps. Our dedicated RRB ALP photo resizer eliminates these frustrations. By selecting the "Photograph" or "Signature" tabs above, the tool instantly calibrates to the exact railway specifications. You can safely upload modern mobile photos (up to 3 MB). The script will automatically crop, resize, and compress the file locally inside your web browser. Similar to our tools for RRB NTPC resizing and RRB Group D, your files remain fully secure and are never transferred to our servers.
