West Bengal is a hub for dedicated government job aspirants. From the iconic West Bengal Police (WBP) Constable and SI roles to the WBPSC Clerkship and Miscellaneous services, the competition is legendary. However, the first hurdle for any Chakrir Prarthi (job seeker) is the technical upload on the recruitment portal.
Every year, applications from Kolkata to Cooch Behar get stuck because the candidate's photo is flagged as too grainy or the signature is too small. As a fellow bank exam aspirant, I know you should be focusing on your syllabus'not on confusing pixel rules. At SarkariPixel.in, we follow a simple principle: Gold Standard clarity first, then size compliance.

Note: Compression Lab is for images (JPG/PNG). For large PDFs, use the safe PDF → Image → compress images → Images → PDF loop.
1) West Bengal technical specifications overview (2026)
West Bengal portals'especially WBPRB (Police Recruitment Board)often use strict aspect ratio and visual quality checks. If your face looks stretched, the background isn't light, or the signature is faint, the portal may reject the upload instantly.
Official specification table (WB jobs)
| Document Type | Dimensions (cm) | File Size (KB) | Requirement |
|---|---|---|---|
| Passport Photo | 3.5 cm × 4.5 cm | 10 KB – 50 KB | White / light background |
| Signature | 4.0 cm × 2.0 cm | 5 KB – 20 KB | Black ink only |
| Caste Certificate | N/A | Under 300 KB | PDF format |
| Marksheet / ID Proof | N/A | Under 500 KB | PDF format |
2) Preparing the perfect WBPRB photo & signature (noise-free)
WB portals are sensitive to digital noise. If you click a photo of your signature under a yellow bulb, the background can look dirty after compression'so the portal sees it as low quality.
Step 1: Use Enhance Lab before resizing
Start with quality. Fix the scan/photo first, then resize to exact dimensions.
- Open Enhance Lab.
- For signature: reduce shadows, make paper whiter, keep ink bold.
- For photo: gently enhance clarity so facial features stay sharp.
- Download the enhanced output and use it for the next step.
Step 2: Resize with the SSC/Universal preset
Good news: SarkariPixel Toolkit now includes a dedicated West Bengal (WBPRB/WBPSC) preset, so you can lock the correct aspect ratio instantly without manual guesswork.
- Open Launch Toolkit.
- Select West Bengal (WBPRB/WBPSC).
- Upload your enhanced photo and fit your face properly (no stretch).
Step 3: Target safe KB values (recommended)
To avoid last-minute failures on slow servers, aim for safe mid-range sizes:
- Photo target: ~40 KB (within 10–50 KB)
- Signature target: ~15 KB (within 5–20 KB)
Use Compression Lab for JPG/PNG images and always preview at 100% zoom before downloading.
3) The certificate challenge (PDFs): the professional SarkariPixel loop
For WBPSC and WBP SI, candidates often upload Madhyamik (10th) admit card (for age proof) and category certificates (OBC-A, OBC-B, SC, ST) in PDF format. The problem: many scans are 15MB, while portals require 300 KB–500 KB.
Important technical note: SarkariPixel does not compress or enhance PDFs directly. We prioritize Gold Standard readability. If your PDF is large, use this safe workflow:
- Convert the PDF pages to images using PDF → Image.
- If needed, clean the page using Enhance Lab so your certificate number, stamps, and signatures remain readable.
- Reduce size using Compression Lab (images only) until you hit a safe target (e.g., 2–50 KB total for a 300 KB limit).
- Rebuild the PDF using Images → PDF.
4) Why privacy-first matters for West Bengal aspirants
Many students in West Bengal rely on cyber cafes or Tathya Mitra style centers for form-filling. This creates a real privacy risk: Aadhaar numbers, signatures, and certificates can remain saved on public systems.
- 100% client-side: processing happens locally in your browser.
- No uploads: your files are not sent to a server.
- Auto-clean: close the tab and your session ends.
This is the security every job seeker in Bengal deserves in 2026.
5) Common rejection reasons in WB portals (avoid these)
- Blue ink signature: WBPRB typically prefers black ink. Blue can fade after grayscale conversion.
- Blurry admit card: if DOB or roll number isn't readable, the PDF fails verification. Enhance the page image before converting back to PDF.
- Spectacles & headgear: unless for religious reasons, avoid caps and reflective glasses that create glare.
- Over-compression: ultra-low KB can destroy text. Always preview before downloading.
6) Pro-tip: build your Bengal Jobs Digital Kit
Don't wait for the last date. Prepare everything today so your upload takes minutes, not hours.
- Prepare your ~40KB photo and ~15KB signature using SarkariPixel.
- Prepare your caste certificate + Madhyamik admit card PDFs under the portal limit using the PDF → Image loop.
- Store them in a folder named WB_JOBS_2026.
If WBPRB/WBPSC servers slow down on the last day, you can still finish your form confidently.
Frequently Asked Questions (FAQ)
Q: Can I use a selfie for West Bengal Police forms?
A: Avoid selfies. Selfies distort facial proportions and often have uneven lighting. Ask a friend to take the photo from ~5 feet away against a white wall, then use Launch Toolkit to crop and size it properly.
Q: My PDF is 3–50 KB but the limit is 300 KB. What should I do?
A: Use the safe loop: PDF → Image → compress images → Images → PDF. Aim for ~250280KB to stay safe under a strict limit.
Q: Does SarkariPixel work on mobile?
A: Yes. SarkariPixel runs in your mobile browser and supports a PWA-style install on many devices, so you can scan, enhance, resize, and convert documents without visiting a cyber cafe.
