UPSC Photo Size, and the Three-Signature Sheet

The signature UPSC asks for is not one signature. It is three, one below the other, in black ink on plain white paper, scanned as a single image — and an ordinary signature resizer hands back one, which is how the upload passes and the scrutiny does not. Give this page your photo and either one signature scan or three.

How to UPSC photo size, and the three-signature sheet

  1. Sign three times down a sheet of plain white paper in black ink, or sign once and let the page repeat it.
  2. Tap Choose your UPSC photo and signatures and pick the photograph first, then the scans.
  3. Check the signature row lists every scan it is about to stack, and correct it if a file landed in the wrong place.
  4. Tap Resize for UPSC, then read the pixel size and the kilobytes printed under each result.
  5. Save both without renaming them — UPSC will not take a file called anything else.

Three signatures, one image

UPSC asks for the three signatures on one sheet, so what you upload is a single tall image, not three files. Hand this page one scan and it repeats that scan three times down the page. Hand it two or three and it stacks what you gave it, in the order the files were picked, and tells you how many it used.

The kilobytes are UPSC’s: 20 to 100 KB for the signature sheet, 20 to 200 KB for the photograph. The rest of the sheet is our arithmetic and we would rather say it than let you carry it away as a rule. Three signatures at 6 by 2 centimetres with even gaps make a sheet of roughly 6 by 9 centimetres, and at 120 dots per inch that is 283 by 425 pixels — which puts the long side inside the 350 to 500 pixels UPSC gives as guidance rather than as a requirement.

Because it is guidance, the grid is allowed to move. Three clean signatures routinely come out under the 20 KB floor, and when that happens the page grows the pixel grid until the file clears it and prints the grid it settled on. It does not pad the file with empty bytes to fake the weight, which is the trick that gets a file accepted at upload and questioned later.

Why your download is called photo.jpg

UPSC dictates the two file names. The photograph must arrive as photo.jpg and the signature sheet as signature.jpg, so the download cannot describe itself the way every other page here does. The real dimensions and the real size are printed beside the file instead of being written into its name — check them there before you save, and do not rename either file afterwards.

What this page cannot see

UPSC wants the face covering at least 75 per cent of the frame with both ear lobes visible, against a plain white background. This page crops to the shape and lands inside the byte window; it does not find your face, measure it, or notice that your hair is over an ear. Nothing here repaints a background either. Those are things to get right in front of the wall, not afterwards.

Worth knowing before you pick an old photograph: the application also captures you live and the two are compared. A photograph from a different decade is a problem no resizer solves.

Questions

I only have one signature scan. Is that enough?
Yes. One scan is repeated three times down the sheet, which is what UPSC asks to see. Three separate scans are stacked as supplied if you would rather sign three times.
Does this check the 75 per cent face coverage?
No, and be wary of any page that says it does. There is no face detection here. The tool fits the shape and the file size; framing your head large enough, with both ear lobes showing, is done by whoever is holding the camera.
My signature sheet came out under UPSC’s 20 KB floor. What then?
The pixel grid grows until the file clears 20 KB, and the page prints the grid it had to use. That is allowed here because UPSC gives its pixel range as guidance, not as a rule — on a portal that fixes its pixels we would tell you instead of quietly moving them.
Where do the centimetres and the DPI on this page come from?
From us. UPSC’s instructions carry the kilobyte windows, the framing rules, the ink and paper, the two file names and a rough pixel range. They set no centimetre size and no DPI, so ours are defaults we chose and label as ours.
