Exam boards revise these figures between cycles, sometimes without announcing it. Treat this page as a starting point and confirm against the notification PDF for your own application.
Preparing the photograph
- Stand about an arm’s length from a plain white wall, in daylight, with someone shooting at eye level. Avoid selfies — the short focal length distorts your face and some portals now detect it.
- Neutral expression, eyes open, mouth closed, no cap or sunglasses.
- Crop to 3.5 × 4.5 cm with the photo tool, selecting India Post GDS from the preset list.
- Confirm the file lands inside 20–50 KB. The tool does this automatically.
Preparing the signature
- Sign in black or dark blue ink on plain white unlined paper, filling a box roughly the shape of 6.0 × 2.0 cm.
- Photograph it flat in good light, with the paper filling the frame.
- Crop tight to the ink and run it through the signature resize tool.
- Check it comes out within 10–20 KB.
Things that get India Post GDS applications rejected
- GDS selection is merit-based on Class 10 marks, so the application window is short and heavily loaded. Prepare your photo and signature files before the portal opens.
- The signature ceiling of 20KB is strictly enforced. Aim for 15–18KB rather than sitting on the line.
- Upload the photograph and signature as separate files. Combined images are rejected.
If the portal still refuses your file
| Error | What it means | Fix |
|---|---|---|
| “File size too large” | Above the ceiling | Reduce image size in KB |
| “File size too small” | Below the floor, usually from over-compressing | Increase image size in KB |
| “Invalid dimensions” | Wrong pixel size or aspect ratio | Resize image in pixels |
| “Invalid file format” | PNG, HEIC or WebP instead of JPG | Convert image to JPG |

How do I resize my India Post GDS photo and signature?
Use the photo and signature tools on this site. Select India Post GDS from the preset list and the crop and file size are applied together. Everything runs in your browser, so your ID photograph is never uploaded anywhere.
Can I upload a PNG instead of a JPG?
No. India Post GDS requires JPG, like almost every application portal. Convert the file first — it takes a few seconds and usually reduces the size at the same time.
