RRB NTPC Signature Resizer — Resize Your Signature to 30–49 KB

What size do I need?

Your signature must be a scanned JPG/JPEG between 30 KB and 49 KB, with image dimensions of at least 140 pixels (width) × 60 pixels (height), scanned at a minimum of 100 DPI. On the form, the scanned signature sits centred in a scan box of 35 mm × 20 mm — sign at your natural size and keep the whole signature inside that area.

The CEN is strict about how the signature itself is made: it must be written by you, in black ink on white paper, in running handwriting (cursive, joined letters) — not in BLOCK, CAPITAL or disjointed letters. Those are stated rejection grounds, along with someone else's signature, a non-white background, non-black ink, a poor-resolution or incomplete signature, a blank image, and a thumb impression in place of the signature. A file can also fail at both ends of the KB range: too big and too small. Always double-check your current notification before you submit — specifications change between cycles.

RRB NTPC photo upload? There isn't one

Many sites still sell a "railway photo resizer" — but for the current RRB NTPC form there is no photo upload at all. Under CEN No. 06/2026 (§14.4), the application module captures your photograph live using your webcam or your phone's front camera while you fill the form. There is no photo file to resize, compress or prepare in advance — and photographing a printed or digital photo instead gets the application summarily rejected. If your live photo does not match your ID proof, the form asks for Annexure VIII, signed by a Gazetted Officer, as proof of identity.

What actually helps on the day:

• Stand or sit in front of a pure plain white background, with nothing else in frame.
• Wear non-white clothing — preferably plain and dark — so you stand out against the background, with shoulders and chest covered.
• Hold the camera at eye level, face straight, centred and fully visible.
• Your head should fill at least half the frame; keep your eyes fully open.
• No cap, mask or glasses for the capture.
• Not happy with the shot? You can retake it before you submit — never photograph an old photo.

The only image you prepare beforehand is your signature — that is what the Resizer above is for.

How to resize your RRB NTPC signature

1. Open the Exam Photo & Signature Resizer (the button above takes you straight there), add your scanned signature, and tap Signature at the top of the tool.
2. Under “Choose your exam”, tap RRB NTPC — Signature. The preset targets 30–49 KB at 140 × 60 px, the minimum dimensions the CEN prescribes. Position your signature inside the frame, centred, and leave the signature clean-up on if you want a whiter background and darker ink.
3. Tap Create my file, check the size shown is between 30 KB and 49 KB, then tap Download.

Why was my file rejected?

What is the RRB NTPC signature size in KB?

For RRB NTPC, your scanned signature must be a JPG/JPEG between 30 KB and 49 KB, with image dimensions of at least 140 pixels wide × 60 pixels high, scanned at a minimum of 100 DPI (CEN No. 06/2026, para 14.5.1). In the Exam Resizer, choose Signature, then the RRB NTPC Signature preset — it targets the 30–49 KB range at 140 × 60 px for you.

Can I upload my photo for the RRB NTPC form?

No. RRB NTPC does not take a photo upload — the application module captures your photograph live using your webcam or your phone's front camera, against a plain white background. Taking a picture of a printed or digital photo instead can get the application summarily rejected. The signature is the image you upload as a file.

Can I sign in capital letters for RRB NTPC?

No. The CEN requires your signature in running handwriting (cursive, joined letters), written by you in black ink on white paper. A signature in BLOCK, CAPITAL or disjointed letters is a stated ground for rejection — as are someone else's signature, a non-white background, non-black ink, a poor-resolution or incomplete signature, a blank image, or a thumb impression instead of a signature.

My signature file is under 30 KB — is that OK?

No. The RRB NTPC range starts at 30 KB, so a smaller file is outside the published range — just as a file over 49 KB is. The Resizer targets a size inside the 30–49 KB range, not just under the maximum — it can also lift a too-small JPG into range without changing the picture.

Is my signature uploaded to a server?

No. FormReady processes your signature in your browser, on your own device. Your files are never uploaded to FormReady.

Will this guarantee my form is accepted?

No tool can guarantee acceptance. FormReady matches the published size specification; final acceptance is decided by the exam portal. Always check the requirements in your current official notification before submitting.

What else does the RRB NTPC form need?

Preparing more than the signature? The Document Pack prepares every document your form needs and downloads them together in one ZIP. Before you upload anything, run each file through the Document Validator — it checks size, format and dimensions against the verified specs and only checks; it never changes your file.

Applying for the free train travel pass as an SC/ST candidate? Your SC/ST certificate is also an upload: a PDF under 400 KB. And if your signature was photographed on a dull or shadowy background, the Signature Cleaner whitens the paper and darkens the ink before you resize, while the Image Compressor adjusts a document image to an exact KB.
