How to Resize a Photo and Signature for SSC, UPSC & Bank Exam Forms

Updated July 2026 ยท 6 min read ยท KaagazPDF Guides

Filling an online exam application should take minutes, but most candidates lose an hour fighting the photo and signature upload. The portal demands an exact pixel size and a tiny file weight, and rejects anything that doesn't match. Here is a clear, portal-by-portal explanation of the numbers and a free way to hit them every time.

The four things every portal checks

  1. Dimensions โ€” the width and height in pixels (e.g. 200 ร— 230).
  2. File size โ€” the weight in KB (e.g. photo 20โ€“50 KB, signature 10โ€“20 KB).
  3. Format โ€” almost always JPG/JPEG.
  4. Content โ€” a plain-background photo and a signature on white paper in dark ink.

Always confirm the exact numbers in the official notification, because they change slightly between recruitment cycles. The method below works for any of them.

Step 1 โ€” Get the photo right

  1. Use a recent, front-facing photo against a plain light wall.
  2. Open Image Studio and choose the Exam photo 200ร—230 preset (or Passport 35ร—45 for cm-based forms). It crops to the exact size without stretching the face.
  3. Slide the quality down until the file is comfortably under the KB limit. For a small photo this is invisible to the eye.
  4. Download the JPG.

Step 2 โ€” Get the signature right

  1. Sign inside a box on plain white paper using a black or dark-blue pen.
  2. Photograph it straight, in good light.
  3. In Image Studio choose the Signature 140ร—60 preset and lower the quality to hit 10โ€“20 KB.
  4. Download.
Save time next cycle: keep one clean photo and one clean signature scan saved on your phone. Every exam season you just re-crop them to that year's required size in under a minute.

If your document upload is also over the limit

Some forms also ask for a scanned certificate or the full application as a PDF with its own size cap. For those, use the Compress PDF guide to bring the file under 100 KB or 500 KB. And if you need to combine your mark sheet and certificate into one PDF, the Merge on mobile guide shows how to do it on your phone.

Why doing it on your phone is safer

Your exam documents carry your photo, signature and roll number โ€” data worth protecting. KaagazPDF processes everything inside your browser, so these images are never uploaded to a server. You get the exact size the portal wants without handing your identity documents to a random website.

Frequently asked questions

The portal says "dimensions not matching" even though the KB is fine. Why?

The pixel width/height is wrong, not the file size. Re-crop using the exact-pixel preset for that exam.

My signature background looks grey, not white. Is that a problem?

Some portals are strict about a white background. Photograph the signature in brighter light, or increase brightness so the paper reads as clean white.

Can I do all of this on a low-end phone?

Yes. The tools are lightweight and run in the browser, so even an entry-level Android handles them.
