UPSC Triple Signature: Size, Pixels and How to Upload It

The UPSC triple signature means you sign three times, one below the other, on plain white paper in black ink, and upload all three as one signature image. This is written into the Civil Services 2026 notice. Guides report the file should be a JPG of 20–100 KB (some say up to 300 KB), roughly 350 to 500 pixels per side. Check the Photos and Signature instructions on upsconline.nic.in before you upload, as those give the exact limits.

UPSC signature specs at a glance

The notice itself does not list KB or pixels; it refers you to the instructions on upsconline.nic.in. That is why guides differ. If you aim for a file of 40–80 KB at about 350 x 500 px, you are inside every range we have seen.

How to sign the triple signature

1. Take a sheet of plain, unruled white paper. Avoid notebook pages with lines or a coloured tint.
2. Use a black pen with a smooth, even line (a black gel pen or ball pen works). Blue ink is not what the notice asks for.
3. Sign three times, one below the other, in your normal running signature. Leave a small gap between them so they do not touch.
4. Keep them the same size and roughly lined up on the left. Three very different signatures look odd and can raise questions later.
5. Sign the same way you will sign on the attendance sheet at the exam and in later stages.

How to scan or photograph it

• Place the paper on a flat, dark surface in daylight, with the flash off.
• Hold the phone directly above the paper so the signatures are not skewed.
• Tap the screen to focus on the ink before you take the photo.
• Crop away everything except the three signatures and a small margin. The shape will be roughly square or a little taller than wide.

How to resize the UPSC triple signature

Our UPSC signature resizer compresses to 20–100 KB and keeps the black & white option on, which makes black ink crisp. One thing to change: its preset is 350 x 150 px, a wide strip made for a single signature. For three signatures stacked vertically, that shape would crop or squash them.

1. Open the UPSC signature resizer and choose your cropped image.
2. Change Height to about 500 (keep Width at 350), or type the pixels your instructions give.
3. Set Fit to "Fit inside with white border" so none of the three signatures is cut off.
4. Download signature.jpg and check that all three signatures are complete and readable, and that the size is within the range.

If the ink still looks grey, run the cropped image through black and white image first and raise the contrast, then resize. Everything runs in your browser, so the signature image never leaves your device.

UPSC signature resize in pixels: does the exact number matter?

The portal checks the file type, the KB size and that the image is within the pixel range it allows. It does not need exactly 350 x 500. What matters is that:

• the image is not smaller than the minimum (often reported as 350 px per side),
• it is not larger than the maximum given in the instructions,
• and the three signatures are clear when viewed at that size.

If your notice gives a different range, edit the width and height fields to fit inside it.

EPFO, CDS, NDA and other UPSC exams

People applying for UPSC's EPFO recruitment (Enforcement Officer/Accounts Officer and APFC posts), CDS, NDA, CAPF or ESE often ask whether the triple signature applies to them too. These exams use UPSC's online application, so it is likely, but the rule came in with the 2026 cycle and notices are exam-specific. Read the signature clause in your own notice. If it asks for a single signature, use the resizer's default 350 x 150 shape instead.

You will also upload a photo. Our UPSC photo guide covers the 3/4 face rule and the name and date question, and the UPSC photo resizer makes the file. For general tips on clean, readable signatures, see how to make a signature clear for online forms.

Common reasons the UPSC signature is rejected

• Only one or two signatures, or four.
• Signatures side by side instead of one below the other.
• Blue ink, or a pencil or felt-tip that smudges.
• Ruled or coloured paper, with lines showing behind the ink.
• Blurred, rotated or skewed scan, often from shooting at an angle.
• Signatures cut off by cropping to a wide strip.
• A digital or typed signature instead of a handwritten one.
• File just over the KB limit. Aim for the middle of the range.

UPSC's 2026 notice says no field can be corrected after you submit, so check the signature preview carefully before the final step.
