UPSC Signature Size: 20 to 100 KB JPG
The short answer
UPSC's 2026 notices say the signature file must be a .jpg between 20 KB and 100 KB. The Civil Services 2026 notice asks you to sign three times, one below the other, on plain white paper in black ink, clear and legible. No pixel size is given, so the tool below makes a tall 800 × 600 picture.
Copy the numbers from your own exam notice: sizes change from year to year and between exams.
The file is made exactly 800 × 600 pixels and under 100 KB (you are told if it ends up below 20 KB). It is counted as 1 KB = 1,000 bytes, so it fits whether the website counts 1,000 or 1,024.
Your files stay on your device. This tool runs entirely in your browser and nothing is uploaded to a server.

Frequently asked questions
Do I sign once or three times for UPSC?
Three times, one below the other, on plain white paper in black ink, according to the Civil Services 2026 notice. Upload that as your one signature file.
What if my UPSC signature file is under 20 KB?
UPSC sets a minimum of 20 KB as well as a maximum of 100 KB. A bigger picture makes a bigger file, so raise the width and height in the tool until the size shown is 20 KB or more.
Can I sign in blue ink for UPSC?
The Civil Services 2026 notice says black ink, so use black. Blue is allowed by some other exams, but not named here.
