What is the maximum PDF size for UPSC document uploads?

Most UPSC certificate and marksheet fields accept PDFs up to 300KB. The photograph field accepts JPEG between 20KB and 50KB, and the signature field accepts JPEG between 10KB and 20KB.

What DPI should I scan documents for UPSC?

UPSC recommends scanning at 200–300 DPI. Higher DPI produces larger files that may exceed the upload limit, while lower DPI can make text illegible for verification.

Can I upload a colour PDF to UPSC?

Yes, UPSC accepts both colour and black-and-white scans. However, compressing a colour PDF without quality loss is harder — use our tool's Recommended compression mode to stay under 300KB.
