India Post Gramin Dak Sevak (GDS) recruitment is one of the most popular opportunities for 10th-pass aspirants seeking a stable government job. Selection is merit-based, but your documents are still screened by automated checks during the online application.
In the 2026 cycle, the portal (indiapostgdsonline.gov.in) continues to be known for its low-KB upload standards. The problem is simple: if you shrink files the wrong way, they become blurry. And if you keep them too big, the portal rejects them.
At SarkariPixel.in, we focus on quick, on-device workflows that help you match portal specs without risking privacy or wasting time at a cyber cafe. This guide breaks down the common GDS upload requirements and shows a step-by-step workflow to prepare a GDS Digital Kit.

1) India Post GDS 2026: official technical checklist
The GDS portal is minimal and does not always provide a cropper or fix button. Your files must already be correctly formatted, sized, and under the file-size limit.
| Document type | Format | Dimensions (pixels) | File size |
|---|---|---|---|
| Passport photograph | JPG / JPEG | 200 × 230 px (preferred) | Under 50 KB |
| Official signature | JPG / JPEG | 140 × 60 px (preferred) | Under 20 KB |
| 10th marksheet | JPG / PDF (if allowed) | Under 200 KB | |
| Caste certificate | JPG / PDF (if allowed) | Under 200 KB |
Important: Always confirm the latest size limits on your portal screen / official notification. If the portal asks for different pixels or KB, follow the portal.
2) Preparing the GDS photo: the white background rule
For India Post, keep it formal. A selfie with shadows or a busy background can look unprofessional and may cause problems later during verification. The goal is a clean, clear face and a plain background that compresses well.
The gold standard photo steps
- Capture smart: use natural daylight facing a window. Avoid harsh overhead lights and shadows.
- Background: stand in front of a solid white or light wall. The cleaner the background, the easier it is to keep the file size low.
- Enhance: open Enhance Lab to brighten and improve clarity if the photo looks dull.
- Resize to pixels: open Resize Lab and set the output to 200 × 230 px.
- Hit the KB limit safely: in Resize Lab, use the Target file size control to aim around 45–48 KB so you stay under 50 KB.
3) The GDS signature: how to hit the 20 KB target
Signature uploads are where most aspirants fail. The file-size limit is small, and if you compress too aggressively, the ink lines become faint.
What works (fast and readable)
- Write it right: use a black or dark blue pen on plain white paper. Avoid thin pencils or light ink.
- Capture flat: take a straight photo from above (no angle) or use a scan app in good light.
- Enhance if needed: use Enhance Lab to increase contrast and reduce background tint.
- Resize to pixels: in Resize Lab, set 140 × 60 px (or what your portal requires).
- Target size: set the Resize Lab Target file size to 18 KB as a safe buffer under the 20 KB limit.
Accuracy note: hitting 18 KB is not a guarantee of acceptance'some portals also validate dimensions and clarity. But smaller, clean files reduce rejection risk when the portal is strict.
4) Using SarkariPixel Launch Toolkit (a fast starting point)
We don't currently show a dedicated GDS preset button. However, you can still use Toolkit as a fast way to get portal-friendly outputs and quick low-KB targets.
- Open Launch Toolkit (or jump directly to SSC).
- Toolkit presets include photo/signature slots with low-KB targets (helpful when you need a small JPG quickly).
- If the GDS portal demands exact pixels (like 200230 / 14060), prefer Resize Lab for the final file'because Toolkit presets are designed for their own exam templates.
5) Converting 10th marksheet: image to PDF (when the portal allows)
If your portal accepts PDF for marksheets/certificates, a single-page PDF can look cleaner than a random JPG. Use Images → PDF to convert your marksheet photo into a PDF.
Accuracy note: the Images → PDF tool converts images into a PDF; it does not promise a specific final KB. For strict under 200 KB rules, first resize/compress the marksheet image (smaller dimensions = smaller PDF), then convert. If the PDF is still too large, upload a JPG instead (if allowed).
6) Privacy: why rural aspirants trust SarkariPixel.in
Many GDS aspirants fill forms at CSCs and cyber cafes, where documents like marksheets and certificates are handled on shared computers. This is exactly where sensitive data can leak.
- SarkariPixel runs client-side: core workflows process files on your device in the browser.
- No account needed: you can prepare files quickly without creating logins.
- Safer by design: you can download your outputs and close the tab'no upload to resizer server dependency for the core workflow.

7) Frequently asked questions (FAQ)
Q: Can I use a photo with a date on it for GDS 2026?
GDS requirements can vary by cycle. If the portal does not demand a dated photo, a clean, recent photo is usually safer. If you already have a dated SSC-style photo, it may still work'but always follow the portal's current instructions.
Q: My signature is 5 KB. Is it too small?
If the portal allows up to 20 KB, extremely small signatures can become blurry. A safe approach is to keep it readable'often around 12–18 KB'while staying under the limit. Use Resize Lab's target file size to tune it.
Q: I don't have a scanner. Can I use my phone camera?
Yes. Capture in natural light, keep the paper flat, and avoid shadows. Then use Enhance Lab to clean the background and Resize Lab to set the exact pixels.
Final word from the founder
To all aspirants aiming for India Post: your 10th marks are your strength, but your documents are your identity. Don't let a file-size or pixel error block a central government opportunity.
