What the RRB NTPC size rules mean
- The RRB NTPC photo is a square (1:1) at 240×240 pixels.
- Its 70KB photo limit is more generous than the typical 60KB across the 14 central government exams on KbSnap (6 of 14 allow a larger file).
- The signature box is a wide box (7:3), 2.3 times wider than it is tall at 140×60 pixels, 30–70KB.
Tips for this spec
- The photo must be at least 30KB as well as at most 70KB. A file that is too small is rejected too, so check both numbers in the result before you download.
- A 30KB minimum is high for a signature. Scan or photograph it in good light at full resolution; a tiny, heavily compressed source may not reach the minimum.
Verify the current requirement in the official RRB NTPC notification before you upload. Sizes can change with each notification.
How to resize your RRB NTPC documents
- 1. Upload: choose a clear JPG, PNG, or iPhone HEIC photo or scan.
- 2. Crop: frame your face or signature inside the box shown for each document.
- 3. Process: KbSnap resizes to the exact pixels and compresses into the allowed KB range.
- 4. Check and download: confirm the pass/fail result, then upload the file to the RRB NTPC portal.

What photo size does KbSnap use for RRB NTPC?
The KbSnap preset for the RRB NTPC photo is 240×240px, 30–70KB, in JPG format. Confirm these numbers in your current notification before you upload, and aim for the middle of the KB range so a re-save does not push the file over the limit.
What signature size does KbSnap use for RRB NTPC?
The KbSnap preset for the RRB NTPC signature is 140×60px, 30–70KB. Sign on plain white paper in the ink colour your notification asks for (black is the safest choice) and crop tightly so the signature is clearly readable.
How do I reduce my RRB NTPC signature to 30–70KB?
Upload your scanned signature in the Signature step above, adjust the crop, and process it. KbSnap resizes it to 140×60px and compresses it into the 30–70KB range, then shows a pass/fail check before you download.
Is my photo uploaded to a server?
No. Cropping, resizing, and compression all happen in your browser using the Canvas API. The file never leaves your device.
Why do different exams need different sizes?
Each exam body sets its own portal validation rules independently — there's no shared standard across UPSC, SSC, banking, and state PSCs.
