What the Polytechnic Admissions size rules mean
- The Polytechnic Admissions photo is a portrait with the same shape as a 35×45mm passport photo at 350×450 pixels.
- Its 50KB photo limit is the same as the typical limit across the 10 academic and teaching exams on KbSnap (4 of 10 allow a larger file).
- The signature box is a wide box (7:3), 2.3 times wider than it is tall at 350×150 pixels, 10–20KB.
Tips for this spec
- 50KB is tight for a 350×450 photo. A plain light background and even lighting leave more of the file size for your face, so it stays sharp.
Same photo and signature spec: Indian Army Agniveer, All India Bar Exam (AIBE), Indian Navy Agniveer SSR/MR, ITI Admission, Teacher Eligibility Test (generic). If you are applying to these too, files made here should also fit — but confirm each notification, since specs change between cycles.
Verify the current requirement in the official Polytechnic Admissions notification before you upload. Sizes can change with each notification.
How to resize your Polytechnic Admissions 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 Polytechnic Admissions portal.

Frequently Asked Questions
What photo size does KbSnap use for Polytechnic Admissions?
The KbSnap preset for the Polytechnic Admissions photo is 350×450px, 10–50KB, 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 Polytechnic Admissions?
The KbSnap preset for the Polytechnic Admissions signature is 350×150px, 10–20KB. 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 Polytechnic Admissions signature to 10–20KB?
Upload your scanned signature in the Signature step above, adjust the crop, and process it. KbSnap resizes it to 350×150px and compresses it into the 10–20KB 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.
