Step by step

How to make the UPSC CDS signature

  1. 1

    Prepare the signature

    Sign on plain white paper with a black pen, in your normal handwriting, not in capital letters.

  2. 2

    Take a clear picture

    Photograph the signature from straight above in daylight, so there are no shadows or tilt.

  3. 3

    Fit it in the frame

    Zoom in until the signature fills the frame with a little white space around it. The frame already has the UPSC CDS shape of 450 x 450 px.

  4. 4

    Make and download

    Press Make. The file comes out as a JPG of 20 to 100 KB, and the tool checks the file itself against the UPSC CDS rules.

Avoid mistakes

Why the signature gets rejected

  • The file is outside 20 to 100 KB, or it is not a JPG.
  • The signature is in capital letters, or does not match the one you will make at the exam.
  • It was signed on lined or coloured paper, or with a pencil or a light pen.
  • The whole page was uploaded instead of a close crop of the signature.
  • A signature from another person or an old application was used.

FAQ

UPSC CDS signature FAQ

What is the UPSC CDS signature size?

350 to 500 pixels in width and height, three signatures one under the other, as a JPG of 20 to 100 KB. The tool makes it 450 x 450 px.

My signature file is too small. How do I reach 20 KB?

A clean signature on white paper makes a very small file. The tool first saves at full quality and, if that is still under 20 KB, adds empty data that viewers ignore, so the file reaches the minimum without changing the picture.

Can I make the UPSC CDS signature on my phone?

Yes. Take the picture with the phone camera, open this page in the browser, fit it in the frame and download the file. Nothing needs to be installed and nothing is uploaded.

Any special rule for the UPSC CDS signature?

Sign three times, one under the other, in black ink on plain unruled white paper.

How do I resize the UPSC CDS photo?

Use the main UPSC CDS photo and signature resizer page for the photo. It also has the full size table for every UPSC CDS document.
