How this tool works
This tool redraws each page as a compressed image and merges everything into one PDF under 1000 KB, the UPSSSC limit for UPSSSC Assistant Statistical Officer (ASO) documents. If the first result is too large, it lowers quality and resolution step by step until the file fits. Text in the result cannot be selected, which does not affect the upload.
