Signature resize for RRB and the live photo rule
Resize your RRB signature
Nothing is uploadedWhat the source says: Scan the signed paper using a minimum resolution of 100 DPI. Image file format: JPG/JPEG only. File size: Between 30 KB and 49 KB. Image dimensions: Minimum 140 pixels (width) × 60 pixels (height). Box size: 35 mm (width) × 20 mm (height).
What it leaves open: The CEN sets a minimum of 140 × 60 px and a 35 × 20 mm box, not an exact pixel size. This preset fills the box at 200 DPI, 276 × 157 px. A signature this size usually comes out below 30 KB as a JPG, so the resizer adds padding bytes after the image data to reach the minimum; the picture itself is not changed.

The 2026 RRB notices for NTPC graduate and undergraduate posts ask for one image file: your signature as a JPG of 30 to 49 KB, at least 140 × 60 pixels, scanned at 100 DPI or more. There is no photo file to resize, because the form takes your photo live. Add a scan or phone photo of your signature above and download the JPG.
RRB signature and photo rules, notice by notice
What each Railway Recruitment Boards notice says about the uploads. rrb.indianrailways.gov.in did not open from our network on 25 October 2026, so we read the two NTPC notices in copies of the official 54- and 57-page PDFs, and the ALP and Group D notices in the PDFs that RRB Chandigarh and RRB Ajmer published.

No notice gives an exact pixel size. The preset turns the 35 × 20 mm box into pixels at 200 DPI, 276 × 157 px, which is above the 140 × 60 px minimum.
How to resize your signature for an RRB form.
Sign inside a 35 × 20 mm box. Draw a box 3.5 cm wide and 2 cm high on white paper and sign in it with a black ink pen, in your usual running (joined) handwriting.
Scan it at 100 DPI or more, or take a straight phone photo in daylight, then crop to the edges of the box so no table or shadow is left around it.
Keep the RRB preset chosen. It makes 276 × 157 px with “Fit all, add white space”, so no stroke is cut, and keeps the file between 30 and 49 KB.
Make the JPG and check the result. It shows the pixel size and the exact bytes; upload it in the signature step of the form.
The photo is done in the form. Stand against a plain white wall in a dark top, with no cap, mask or spectacles, keep the camera at eye level and your eyes open, and retake it until it is clear.
When the 2026 NTPC applications close
The dates printed in the two NTPC notices, for the online form, the fee and the paid correction window:
| Notice | Apply online | Fee by | Corrections |
|---|---|---|---|
| CEN 06/2026, Graduate | 8 October to 6 November 2026, 23:59 | 8 November 2026 | 9 to 18 November 2026 |
| CEN 07/2026, Undergraduate | 15 October to 13 November 2026, 23:59 | 15 November 2026 | 16 to 25 November 2026 |
The form is on rrbapply.gov.in. If you ask for a free train travel pass as an SC or ST candidate, you also upload your certificate as a PDF under 400 KB: the PDF compressor for 300 KB keeps it under that.
The live photo: what CEN 06/2026 asks
- A pure plain white background, with no scenery, plants, people or animal pictures behind you.
- Non-white clothes, preferably plain and dark, covering your shoulders and chest.
- The camera at eye level, your face centred in the frame on screen, looking straight ahead.
- Your head filling at least 50% of the photo, with your elbows and everything below your chest out of the frame.
- No cap, mask, glasses or spectacles, and nothing covering your face. Your eyes fully open, or the photo is not captured.
- If the live photo does not match your photo ID, the form asks you to upload Annexure VIII signed by a Gazetted Officer.
Why RRB rejects a signature
The grounds the notices list, at any stage of the recruitment.
Someone else's signature. The signature has to be written by the candidate.
Capital or block letters. Sign in running handwriting, the way you will sign at every later stage.
A non-white background or non-black ink. Use a black ink pen on white paper.
A blurred, cut-off or blank image. Poor resolution, a partly visible signature and an empty file are all grounds.
The wrong image. Uploading another picture, or a thumb impression where the signature belongs.
Questions
What is the RRB NTPC signature size?
A JPG or JPEG of 30 KB to 49 KB, at least 140 pixels wide and 60 pixels high, scanned at 100 DPI or more and centred in the 35 mm × 20 mm box on the form. CEN 06/2026 (NTPC Graduate), CEN 07/2026 (NTPC Undergraduate), CEN 01/2026 (ALP) and CEN 09/2025 (Group D) print the same rule. The 140 × 60 px is a minimum; the preset here makes 276 × 157 px, the box at 200 DPI.
Do I need to upload a photo for RRB NTPC 2026?
No. The notices say candidates are not required to upload a pre-existing photograph. The form captures a live photo through your computer's webcam or your phone's front camera, and you can retake it until you submit. Pointing the camera at a printed or on-screen photo gets the application rejected.
What background does the RRB live photo need?
CEN 06/2026 and CEN 07/2026 ask for a pure plain white background with no scenery, plants, people or animal pictures behind you. Wear non-white clothes, preferably plain and dark, that cover your shoulders and chest. Your head should fill at least half of the photo, and your elbows and everything below your chest should stay out of it.
Why does my RRB signature come out under 30 KB?
A signature is mostly white paper, so a JPG of 276 × 157 px is usually far below 30 KB, even at full quality. With the preset chosen, the resizer adds padding bytes after the image data until the file reaches 30 KB, without changing a pixel, and the result shows the exact byte count.
Can I sign in capital letters for RRB?
No. The notices ask for running (joined) handwriting in black ink on white paper, not block, capital or disjointed letters, and list a signature in capitals among the grounds for rejection. Sign the same way every time: your signature is matched at the exam, document verification, medical examination and appointment.
What if I cannot sign?
The notices let some Persons with Benchmark Disabilities whose disability prevents them from signing upload a scanned fingerprint in the signature step instead, in this order: left thumb, right thumb, any finger of the hands, then any toe.
Is my signature uploaded to FormAssets?
No. The image is resized inside your browser and the JPG downloads to your device. There is no account and no copy on a server.
Before you upload: what the resizer cannot check
FormAssets makes the JPG at the pixels and file size you choose and shows the result. It cannot judge your handwriting, and the live photo is taken by the RRB form itself.
Each notice can change the rules. Before you apply, open your CEN on rrb.indianrailways.gov.in (opens in a new tab); each row above shows the date we read it.
