NDA Signature Resizer
Resize your signature for UPSC NDA and NA applications — adjust the file size, crop extra space, and get a clean JPG ready for upload.
How to Resize a Signature for NDA
Prepare your signature in three simple steps:
- 1
Upload your signature
Choose a clear scanned signature or photo from your phone, tablet, or computer.
- 2
Resize and adjust
Set the required file size or dimensions and crop unnecessary white space if needed.
- 3
Preview and download
Check that the complete signature is clear and readable, then download the final image for your NDA application.
NDA Signature Requirements 2026
UPSC's current instructions ask for a clearly visible signature scanned in JPG format, sized between 20 KB and 300 KB.
| Requirement | NDA Application |
|---|---|
| File format | JPG |
| File size | 20 KB – 300 KB |
| Signature | Clear and properly visible |
| Dimensions | Not fixed by UPSC — follow whatever your current application screen shows |
| Image quality | Avoid blurry or poor-quality images |
Important
Always check the latest UPSC NDA & NA notification and application portal before submitting — instructions can change between examination cycles. Official source: UPSC Active Examinations.
How to Prepare a Clear NDA Signature
- Sign on plain paper with dark ink so it scans clearly.
- Keep the paper flat and well-lit — shadows are the usual reason a clean signature turns blurry after compression.
- Crop tight around the signature before resizing; extra white space eats into your KB budget fast at a 300 KB ceiling. Our signature cropper trims the margins in one step.
- Preview the final JPG before uploading, and run it through the signature size checker to confirm it lands inside 20–300 KB — UPSC holds candidates responsible for catching a bad file themselves.
Why Is My NDA Signature Not Uploading?
If the application does not accept your signature, check these common issues first:
| Problem | Solution |
|---|---|
| File size is too large | Reduce the image to the required size without making the signature blurry. |
| File is below the minimum size | Increase the image quality or dimensions while keeping it within the allowed range. |
| Wrong image format | Save the signature as JPG according to the current UPSC instructions. |
| Blurry or faint signature | Start with a clearer scan or photo and avoid excessive compression. |
| Too much white space | Crop unnecessary margins around the signature before resizing. |
| Signature is cut off | Make sure the complete signature is visible in the final image. |
| Poor-quality image | Replace the source image with a clearer scan or photo. |
Frequently Asked Questions
What is the NDA signature size in KB for 2026?
20 KB to 300 KB, per UPSC's current guidance. Worth a quick check against this year's notification since the range has shifted before.
What format is required for an NDA signature?
JPG. That part's stayed consistent across recent cycles, but confirm your notification hasn't changed it.
Why is my NDA signature being rejected?
Usually one of: wrong format, outside the 20–300 KB range, or the signature looks cut off or blurry after compression. UPSC puts the responsibility on candidates to catch this before submitting.
Can I resize my NDA signature on mobile?
Yes — works from any modern mobile browser, no software needed.
Can I use the same signature for NDA and CDS?
Only if it fits both size ranges — they're not identical, so check each form's spec separately with our CDS signature resizer rather than assuming. The same caution applies to other defence routes like the Territorial Army photo & signature resizer, which runs on a separate portal with its own limits.
