Most online applications for government exams in India asks for scanned photograph and signature in specific pixel size and image size such as -
Upload Scanned Images of Photograph and Signature:
The scanned images of photograph and Signature should be in jpg/jpeg format only.
Size of the photo image must be greater than 4 kb and less than 40 kb.
Size of the signature image must be greater than 1 kb and less than 30 kb.
Dimension of photograph image should be 3.5 cm(width) x 4.5 cm(Height) only.
Dimension of signature image should be 3.5 cm(length) x 1.5 cm(Height) only.
Such file size limits are set so that the web server space is not exhausted by letting candidates upload any image size as several lakhs or even crores of candidates apply for government exams.
