Getting an RRB signature to 30 KB to 49 KB
RRB's Centralised Employment Notification 09/2025 asks for a scanned signature, in running handwriting in black ink on white paper, as a JPG or JPEG between 30 KB and 49 KB and at least 140 x 60 pixels.
The form places the signature in a 35 x 20 mm box, so this page makes it 350 x 200 pixels, the same shape and well above the minimum. It is saved at the best quality under 49 KB, and because a signature at that size is usually well under 30 KB, it is padded up to 30 KB with an invisible comment inside the file. The signature is exactly the same.
Tips
- Sign in running (joined-up) handwriting. The notice rejects block, capital or disjointed letters.
- Take the photo close around the signature, then drag the crop box so it keeps all of it.
- Each notification sets its own rules. The RRB photo is captured live in the application, so there is no photo to upload.

Questions
Why would RRB reject my signature?
CEN 09/2025 lists the grounds: a non-white background, ink other than black, block or capital letters, poor resolution or an unclear image, a signature that is partly cut off, a blank, a thumb impression instead of a signature, or someone else's signature. A rejection can happen at any stage of recruitment.
Where do I sign again after the RRB application?
Your signature must match the ones taken at the exams, document verification, the medical examination and appointment. At the CBT you write a self-declaration, sign and put your left thumb impression on the e-call letter in front of the invigilator. Signing in capital letters there is rejected too.
Do I upload my RRB signature again before document verification?
RRB advises candidates shortlisted for document verification to upload scanned copies of their photo and signature in true colour before their DV date, through the portal oirms-ir.gov.in/rrbdv. For the application itself, scan the signed paper at a minimum of 100 DPI.
