How to Resize and Upload Your Signature for RRB Application

RRB Signature Resizer – Create Perfect Digital Signatures for Railway Exams | ImgConvert99

RRB (Railway Recruitment Board) online application forms only accept signatures in a specific size and dimension. If your signature file is too large, too small, or in the wrong ratio, the portal may show errors like “invalid signature” or “incorrect size”.

The RRB Signature Resizer by ImgConvert99 lets you crop, resize and compress your digital signature in one place – tailored to typical RRB requirements so that your form can be submitted without issues.

📌 Typical RRB Signature Requirements (Example)

Exact specifications may vary from one notification to another, but in most RRB exams, the digital signature is expected to follow guidelines similar to:

• Dimensions: around 140 × 60 pixels (or similar aspect ratio)
• File size: usually between 10 KB and 20 KB
• Format: JPG / JPEG
• Background: plain white, with a clear signature in blue or black ink

This tool is designed with these common requirements in mind so that your file is more likely to be accepted by the RRB portal. However, you should always check the latest official notification for the exact rules of your specific exam.

🔍 Who Should Use the RRB Signature Resizer?

• Candidates applying for RRB Group D, NTPC, ALP, Technician and similar posts
• Applicants filling forms for Railway Apprentice, Junior Engineer and other jobs
• Students who don’t want to depend on a cyber café for simple editing
• Anyone who wants to prepare a valid digital signature directly from mobile or laptop

🚀 How Does the RRB Signature Resizer Work?

1. Sign your name on a clean white sheet using blue or black ink.
2. Take a clear, well-lit photo of the signature (from the top, without shadows).
3. Upload the image to the RRB Signature Resizer on ImgConvert99.
4. Use the cropper to select only the clean signature area.
