1) RBI Grade B 2026: official specifications at a glance
Before you resize anything, lock your targets. RBI often follows bank-exam standards, but is strict in verification. Treat these as your working checklist and confirm the final limits on the portal.
Image-based documents (JPG/JPEG)
| Document | Dimensions (pixels) | File size (KB) |
|---|---|---|
| Passport photograph | 200 x 230 | 20-50 KB |
| Signature | 140 x 60 | 10-20 KB |
| Left thumb impression | 240 x 240 | 20-50 KB |
| Handwritten declaration | 800 x 400 | 50-100 KB |
PDF-based documents (marksheets, certificates, ID proofs)
| Document | Format | File size limit |
|---|---|---|
| Graduation marksheet/degree | Under 500 KB | |
| Category certificate (OBC/SC/ST) | Under 500 KB | |
| Photo ID proof | Under 500 KB |
2) Preparing your photo & signature (image workflow)
Your photo and signature are the face of your application. The goal is simple: keep them sharp while staying safely under the KB cap.
Step 1: Enhance (for mobile photos)
If you click your signature/thumb on a phone, the paper often looks gray and the ink looks dull. Use Enhance Lab first to whiten the background and sharpen ink lines.
Step 2: Resize, then compress
- Resize: Use Resize Lab and set the exact dimensions (example: 200 x 230 for photo).
- Compress: Use Compression Lab and aim mid-range (example: target 40 KB for a 20-50 KB window).
3) Handling graduation marksheets (PDF workflow)
RBI Grade B often needs organized academic records. If you must upload multiple semester marksheets as a single PDF, do it in order and keep it under 500 KB.
How to merge multiple marksheets into one PDF
- Convert to PDFs: If you have marksheets as images, convert each set using Image to PDF.
- Merge in order: Open Merge PDFs, upload semester PDFs in correct order (Sem 1 first).
- Download the merged PDF: Keep it as one clean file for the portal.
If the merged PDF is over 500 KB (the safe loop)
Some PDFs are heavy because pages are scanned as large images. If your merged file crosses 500 KB, use this clarity-safe loop:
- Convert the PDF pages via PDF to Image.
- Improve readability via Enhance Lab (optional but useful for shadows).
- Reduce size using Compression Lab while keeping text readable.
- Recreate a clean PDF using Image to PDF.
4) Launch Toolkit: shortcut to RBI success
Jumping across tools wastes time. The Launch Toolkit is designed as a one-stop station for bank exam uploads.
- Banking preset: You do not have to remember 200 x 230 or 140 x 60.
- Guided order: Enhance first, resize second, compress last (this order keeps files sharp at low KB).
5) Common errors to avoid in RBI forms
- Signature in capital letters: Like other bank exams, running handwriting is expected.
- Blurry thumb impression: If ridge lines are not visible, it can cause trouble at biometric verification. Enhance contrast first.
- Merged PDF order: Keep Sem 1 first page, then Sem 2, and so on. Organized documents reduce verification friction.
- Borderline KB files: Uploading at 499.9 KB is risky. Target 430-4–80 KB when the limit is 500 KB.
6) Privacy: why your marksheets are safe with SarkariPixel
Marksheets include personal data, roll numbers, and parentage. Cloud converters are a privacy risk. SarkariPixel tools are client-side: merging, conversion, and compression happen locally in your browser memory and files are not uploaded to our server.
FAQ
Can I upload a colored scan of my marksheet?
Yes. Colored scans are fine as long as they are within the 500 KB limit. If your file is too big, use the PDF-to-image loop (PDF to Image → Compress → Image to PDF) to reduce size without destroying text.
What if I do not have a scanner?
Use your phone in bright light and keep the page flat. Then use Enhance Lab to remove shadows and make it look like a professional scan.
Is the handwritten declaration the same as IBPS PO?
Usually yes, but always check the current RBI Grade B notification. You can also use our IBPS declaration guide as a starting point and then follow the 800 x 400 and 50-100 KB targets.
Final advice
RBI Grade B is a marathon. Your mind should be on inflation, GDP, and circulars, not on upload errors. Spend 5 minutes to organize your files with the Launch Toolkit, submit confidently, and get back to preparation.
