UPSC CSE Photo & Signature Size: Exact Pixels and KB for 2026
UPSC CSE requires a 4.5cm x 3.5cm photo (20–50KB) and 4.5cm x 2cm signature (10–20KB) with specific pixel/DPI combos. Resize instantly and free in your browser.
The UPSC Civil Services (CSE) application requires the photo and signature to satisfy both dimension and file-size checks. The recommended photo is 4.5cm x 3.5cm in JPEG at 20–50KB, and the signature is 4.5cm x 2cm at 10–20KB. UPSC's One Time Registration (OTR) is strict about these ranges.
This tool resizes and compresses your photo and signature to the UPSC combination — exact ratio, exact DPI, and inside the KB limits.

Frequently asked questions
What is the exact UPSC photo size?
4.5cm x 3.5cm (531 x 413 pixels at 300 DPI), JPEG, between 20KB and 50KB. The face should cover about two-thirds of the frame with a light background.
What is the UPSC signature size?
4.5cm x 2cm, JPEG, between 10KB and 20KB. Write it in black ink on white paper and scan it clearly.
Which DPI should I use for the UPSC photo?
300 DPI is the safest because it produces the exact 4.5cm x 3.5cm physical size at the commonly accepted 531 x 413 pixel count. This tool lets you pick the DPI.
Why does UPSC reject photos?
Common reasons: wrong dimensions, file size outside 20–50KB, dark background, cropped forehead/chin, or blurry low-resolution images.
