How to Resize Signature for Railway Exam
Upload your scanned signature or a clear photo of the signed paper. This page automatically applies the railway signature defaults: 140 pixels width, 60 pixels height, JPG format, and a target size inside the 10KB to 20KB range. For best results, use a clean scan with black ink on white paper and crop the image close to the signature before resizing.
After upload, check the live preview. The signature should be readable and should not touch the edges. If the output is below 10KB or above 20KB, adjust the target KB value and process again. Download the JPG file only after the status shows it is within the railway range. Keep the same signature for admit card, attendance sheet, and verification across all railway exam stages.
Railway Signature Requirements 2024-25 — All RRB Exams
All Railway Recruitment Board examinations require the same signature upload specification: 140×60 pixels, 10KB to 20KB, JPG or JPEG format. This applies to RRB NTPC, RRB Group D, RRB ALP (Assistant Loco Pilot), RRB JE (Junior Engineer), RRB SSE (Senior Section Engineer), and all other RRB-conducted examinations. The signature should be handwritten on white paper using black or dark blue ink.
The signature is used to verify identity at later stages including admit card, examination hall attendance, and document verification. Therefore, sign naturally and consistently. Do not stretch the signature to fit the box. This tool resizes the whole image to 140×60 pixels and compresses it to the selected KB target, so start with a straight, clear scan for the best final file.
How to Scan Signature for Railway Forms
A flatbed scanner gives the cleanest result. Place the signed paper flat on the scanner glass, scan at 300 DPI, and save as JPG. If you do not have a scanner, use a phone camera in bright daylight. Put the paper on a flat surface, hold the phone directly above it, and avoid angled photos because they make the signature look slanted and uneven.
Crop the image to include only the signature and a small amount of white space. Remove shadows, table edges, and extra paper area before resizing. Do not use pencil or light gel pen because compression can make it fade. A bold black ballpoint signature on white paper remains clear even after being reduced to 140×60 pixels and 10-20KB.
Railway Signature Rejection Reasons
Signatures are rejected when they are too light, blurry, cut off, outside the permitted KB range, or saved in the wrong format. A 500KB scan will not upload, and an over-compressed 3KB image can look unclear. Colored paper, shadows, folds, and background patterns also create problems because the signature must be easy to compare during verification.
Another mistake is using a typed name or digitally generated signature. RRB portals require a handwritten signature image. If your signature touches the edges, crop again with a little white space around it. If the portal says invalid file, make sure the downloaded file is JPG, 140×60 pixels, and between 10KB and 20KB.

Final Checklist Before Uploading to Railway Portal
Before you submit the online form, open the downloaded file once and confirm that it is the processed copy, not the original large image. Check the filename, the preview, and the file size shown by your device. Many candidates resize correctly but accidentally upload the original file from the camera folder. Keeping a separate folder named railway application images reduces this mistake.
Also verify that the signature is clear, not cut off at edges, and the file opens without error. If the railway portal still rejects the image, recheck three things first: file extension must be .jpg, file size must be inside the allowed KB range (10-20KB), and dimensions must be exactly 140×60 pixels. These three checks solve most upload errors without needing any advanced editing.
Privacy and Offline Processing
This toolkit is built for static hosting, so image processing happens in your browser with the Canvas API. The signature is read by your device, drawn to a temporary canvas, compressed to the target size, and offered as a downloadable file. There is no backend upload step in this workflow. That matters for government exam applicants because photos, signatures, and identity documents are personal records and should not be sent to unknown servers just to resize them.
When you double-click the page locally, the tool uses hardcoded Railway fallback values so it can still work without a server. Either way, the browser does the image work locally. Closing the tab removes the working image from memory. You should still keep your downloaded file safely until the recruitment process is complete.
