RBI Grade B Photo & Signature Resizer
RBI Grade B applications need four separate uploads — photograph, signature, left thumb impression, and a handwritten declaration — each with its own size and pixel range. Prepare all four here before you open the application form.

RBI Grade B Photo Resizer
RBI Grade B's application window runs once a year. The specifications below are based on recent official RBI instructions and are a solid starting point for your next cycle — just confirm against whichever notification you're applying under, since RBI does update these numbers between years.
RBI Grade B Upload Requirements
RBI Grade B asks for four documents, each with its own pixel and file-size range:
| Document | Dimensions | File Size | Format | Notes |
|---|---|---|---|---|
| Photograph | 200 × 230 px (preferred) | 20 KB – 50 KB | JPG / JPEG | Recent passport-style photo, light or white background, no caps or dark glasses |
| Signature | 140 × 60 px (preferred) | 10 KB – 20 KB | JPG / JPEG | Black ink on white paper, not in capital letters |
| Left Thumb Impression | 240 × 240 px (preferred, 200 DPI) | 20 KB – 50 KB | JPG / JPEG | Black or blue ink on plain white paper, properly scanned and not smudged |
| Handwritten Declaration | 800 × 400 px (preferred, 200 DPI) | 50 KB – 100 KB | JPG / JPEG | English, white paper, black ink, own handwriting, not in capital letters — exact wording is specified in the notification |
Important
These figures follow RBI's own upload guidelines. RBI has updated specific numbers between recruitment cycles before, so confirm against your current notification before uploading.
About the Live Photo Capture Step
Recent RBI Grade B application instructions include a live photo capture step in addition to the photograph you upload. After uploading your prepared photo, the portal asks you to either use your webcam directly or scan a QR code with your phone to take a real-time picture. Keep a plain, well-lit background ready for this step, since it happens during the application itself, not before it.
This is separate from the resizing steps below and can't be skipped by uploading a second photo file.
Preparing Your Files
- Take the passport photo against a plain, light background — RBI's guidance is strict about caps, dark glasses, and busy backgrounds.
- Sign on white paper in black ink, avoiding all-capital-letter signatures — RBI explicitly rejects these.
- For the thumb impression, use a light, even press — make it clean and single, and redo it if it looks smudged or unclear. Our thumb impression resizer covers this document on its own if you only need to fix that one.
- Write the handwritten declaration exactly as worded in your notification — don't paraphrase it, and keep it in English unless the notification says otherwise.
- Scan or photograph each document separately rather than trying to crop multiple items from one combined scan.
How to Resize

- 1
Upload each document
Photo, signature, thumb impression, and declaration, one at a time.
- 2
Pick the matching preset
Each document has its own pixel and KB target.
- 3
Crop and compress
Bring the file into range without losing legibility, especially for the thumb impression and declaration.
- 4
Download all four
Keep them ready before you start the actual RBI application, since the live photo step happens separately inside the portal.
If a file lands above its ceiling, run it through our image compressor or signature compressor, then confirm each one with the signature size checker before you upload.
Common Upload Problems
| Problem | Cause |
|---|---|
| Photo or signature rejected | Outside the KB range, wrong pixel dimensions, or saved in a format other than JPG/JPEG |
| Thumb impression looks smudged | Too much ink or pressure — a lighter, single press usually scans cleaner than a heavy one |
| Declaration doesn't match the required wording | Write the declaration exactly as given in the current notification — RBI checks the text itself, not just the file format |
| Live photo step won't complete | Check camera permissions, lighting, and the instructions shown on the capture screen |
Frequently Asked Questions
What size should my RBI Grade B photo and signature be?
Photo: 200×230 px, 20–50 KB. Signature: 140×60 px, 10–20 KB. Both in JPG/JPEG.
Is the live photo capture the same as the photo upload?
No — they're two separate steps. The uploaded photo is a prepared file; the live capture happens inside the portal using your webcam or phone at the time of applying.
What size is the RBI Grade B left thumb impression and declaration?
Thumb impression: 240×240 px, 20–50 KB. Declaration: 800×400 px, 50–100 KB. Both per RBI's standard upload guidelines — confirm against your current notification since exact figures can shift between cycles.
Can I use my RBI Assistant photo and signature for RBI Grade B?
The pixel dimensions are usually the same, but RBI Assistant and Grade B are separate notifications, and other details have differed between them in past cycles. Check your specific notification before reusing a file — our RBI Assistant photo & signature resizer has that exam's own presets if you're applying to both.
