India Post GDS recruitment needs two separate image uploads — a photograph and a signature — and each one has its own exact pixel size, ratio, and KB limit. A reliable India Post GDS Image Resizer handles both in one place, so candidates can prepare their uploads correctly without any technical know-how.
This guide explains the complete process in simple steps — what the GDS portal actually checks, the correct specifications, how to resize your image properly, common errors to avoid, and answers to the questions candidates ask most.
Understanding India Post GDS Image Requirements
The online application system for India Post GDS runs automated checks that immediately flag non-compliant images. If your photo or signature doesn’t match the exact dimensions, ratio, format, or file size, the upload is blocked before a human ever reviews your form. This makes using a precise India Post GDS Image Resizer not just helpful, but necessary for a smooth submission.
Essential Image Specifications for GDS 2026
Since “image” on the GDS portal covers two different uploads, here are both specifications side by side:
| Detail | Photograph | Signature |
|---|---|---|
| Dimensions | 320 × 400 pixels | 300 × 120 pixels |
| Aspect ratio | 4:5 (portrait, ±10% tolerance) | 5:2 (landscape, ±10% tolerance) |
| File size | 30 KB to 100 KB | 20 KB to 100 KB |
| Format | JPG / JPEG only | JPG / JPEG only |
| Background | Plain white or light | Plain white paper |
Always verify these numbers against the current official India Post GDS notification, since specifications can be updated in every recruitment cycle. For a deeper, step-by-step guide on either upload, see our dedicated GDS Photo Resizer and GDS Signature Resizer guides.

Step-by-Step Image Resizing Process
1. Prepare Your Original Image
- Use good, even lighting
- Stand against (or sign on) a plain white background
- For a photo: look straight at the camera with a neutral expression
- For a signature: sign in one clean, horizontal line
2. Upload to the Resizer Tool
Click the “Upload Image” button above and select your photo or signature file.
3. Select Photo or Signature, and Adjust
Pick the correct type so the tool locks the right ratio automatically — 4:5 for a photo, or 5:2 for a signature — and sets the output format to JPG.
4. Process and Download
Click the process button and download your correctly sized image — 30–100 KB for a photo, or 20–100 KB for a signature.
5. Verify Before Uploading
Check the final image’s dimensions and file size to confirm it meets the requirements before you submit it on the GDS portal.
Pro Tips for a Perfect GDS Application
- Use a recent photograph, not older than about 6 months
- A studio-clicked photo works well if one is available nearby
- Wear simple, neat clothing for the photo
- Avoid shadows on your face, background, or signature paper
- Keep a backup of both the original and the resized files
- Rename files clearly — photo.jpg and signature.jpg
Common Errors and Solutions
- Error: File size outside the allowed range > Solution: Use compression (or the upscale option) to bring it into the correct KB range for that image type
- Error: Wrong aspect ratio > Solution: Resize to exactly 4:5 for a photo, or 5:2 for a signature
- Error: Invalid format > Solution: Convert the file to JPG/JPEG
- Error: Blurry or pixelated image > Solution: Start from a clear, high-quality original
- Error: Dark or busy background > Solution: Retake against a plain white/light background
