Securing a government job in the national capital through DSSSB is a prestigious milestone. Whether you are applying for teaching posts (TGT/PGT), junior assistant roles, or technical vacancies, the Delhi Subordinate Services Selection Board is known for some of the most specific document requirements in India.
The most common hurdle? The postcard size photograph. Unlike most portals that accept 3.5 cm × 4.5 cm passport photos, DSSSB can require a much larger photo for certain stages. If you upload a stretched or low-quality image, your application may fail scrutiny.
As a fellow bank exam aspirant, I know how frustrating it is to visit a studio only for one special size. SarkariPixel.in helps you generate DSSSB-style postcard photos from the comfort of your home with a clarity-first workflow.
Quick links (tools)
Note: Compression Lab is for images (JPG/PNG). For large PDFs, use PDF → Image → compress images → Images → PDF.
1) DSSSB 2026: the postcard size mystery
A postcard photo is essentially a larger identity photo. DSSSB uses it to ensure your facial features (eyes, nose, ears) remain sharp enough for biometric and manual checks'even after printing or portal downscaling.
Technical specification table (DSSSB-style standards)
| Document Type | Format | Required Dimensions | File Size (KB) |
|---|---|---|---|
| Passport Photo | JPG / JPEG | 3.5 cm × 4.5 cm | 20 KB – 50 KB |
| Postcard Photo | JPG / JPEG | 5 inches × 7 inches | 50 KB – 300 KB |
| Signature | JPG / JPEG | 140 × 60 pixels | 10 KB – 40 KB |
| Thumb Impression | JPG / JPEG | 110 × 140 pixels | 10 KB – 40 KB |
Always treat the latest DSSSB notification/portal as final. If your form shows different pixel or KB limits, follow the portal numbers.
2) Preparing the 57 postcard photo (the SarkariPixel way)
Because postcard photos are big, any noise or grain in the original image becomes much more visible. The goal is simple: clean background + sharp face + correct 5:7 ratio.
Step 1: Enhance first (clarity before size)
- Open Enhance Lab.
- Upload your best passport-style photo (avoid WhatsApp-forwarded images).
- Enhance lightly so the background looks clean and facial features remain crisp (avoid over-sharpening).
- Download the enhanced output.
Step 2: Resize to 57 inches (manual setting)
DSSSB postcard photos follow a strict 5:7 ratio. You can create this exactly in the Resize Lab:
- Open Image Resize Tool.
- Switch unit to Inches.
- Enter Width: 5 and Height: 7.
- Use padding/fit controls so your face looks natural (no stretch).
- Download as JPG and then use Compression Lab to land in the safe range (e.g., 150250KB).
3) The NTA preset hack for DSSSB (fast postcard zone)
Need a shortcut? Many NTA exams (like NEET) require a postcard-like photo. Our Toolkit's NTA preset quickly moves you into a high-resolution postcard zone (commonly 46). Then you finalize DSSSB's 5×7 in Resize Lab.
- Open Launch Toolkit.
- Select NTA → NEET Postcard Photo.
- Download, then open Resize Lab and set 57 inches for the final DSSSB requirement.
4) Converting certificates (JPG to PDF) for Delhi jobs
DSSSB can require category certificates (SC/ST/OBC-Delhi) and PWD certificates in PDF. If your scanned PDF is too large (e.g., 2MB) and the portal asks for 300 KB, use a clarity-safe method.
Important reminder: SarkariPixel does not compress PDFs directly. To reduce PDF size without ruining text, use the PDF → Image loop.
- Convert your PDF to images using PDF → Image.
- If the certificate text looks gray, clean it using Enhance Lab.
- Reduce the image size using Compression Lab (aim ~2–50 KB for a 300 KB limit).
- Rebuild a sharp PDF using Images → PDF.
This keeps the certificate serial number and stamps readable'usually the first thing verification officers check.
5) Why privacy matters for Delhi aspirants
In a metro city like Delhi, online scams and shady free converters are common. Many sites upload your Aadhaar or certificates to unknown servers.
- 100% client-side: documents never leave your device.
- No uploads: everything is processed in your browser memory (RAM).
- Zero access: we cannot view or store your ID proofs.
6) Common rejection reasons in DSSSB forms
- Wrong postcard ratio: uploading a square/portrait crop into a 57 slot causes stretching.
- Blue ink signature: DSSSB typically prefers black ink; blue can fade after grayscale conversion.
- Thumb impression too small: very low KB hides ridge lines; aim a safe ~25KB while staying inside portal range.
- WhatsApp compression: forwarded images often become blurry'use original camera files.
Frequently Asked Questions (FAQ)
Q: Can I use the same photo for DSSSB as I used for SSC?
A: You can use the same image, but you must resize it. SSC typically uses 3.5×4.5 cm, while DSSSB can require a larger 5×7 inch postcard photo.
Q: Is date on photo required for DSSSB 2026?
A: Check your specific notification. Even when not mandatory, DSSSB often expects a recent photo. Adding date text using the Resize tool's text overlay can be a safe way to show recency.
Q: My PDF marksheet is blurry after conversion. How do I fix it?
A: Convert the PDF to images, enhance the image for stronger contrast, then rebuild the PDF. Use PDF → Image → Enhance → Images → PDF.
