RRB NTPC Signature Upload Errors
If your signature is not being accepted during the application process, check these common problems first.
| Common Problem | Likely Cause | What to Do |
|---|---|---|
| File size too large | Image is above the 49 KB limit. | Compress the image until it falls within the required range. |
| File size too small | Excessive compression has reduced the file below 30 KB. | Start with a clearer source and adjust compression carefully. |
| Wrong dimensions | Image is smaller than the required minimum. | Resize to at least 140 × 60 pixels. |
| Low resolution | Source image was prepared below the required resolution. | Use a scan or image prepared at a minimum of 100 DPI. |
| Unsupported format | Image is not JPG/JPEG. | Convert or download the final image as JPG/JPEG. |
| Blurry signature | Poor source image or excessive compression. | Start with a sharper signature image. |
| Too much white space | Large blank margins surround the signature. | Crop unnecessary margins while keeping the complete signature visible. |
| Wrong ink or style | Non-black ink or block/capital letters were used. | Use your normal running signature in black ink. |
If the final image still looks unclear after resizing, start with a better-quality source instead of repeatedly compressing the same image.
