@jwadulhssn Can you provide sample PDF file which is causing memory leak, Now I made some changes and I could convert 40 Mb file with 312 pages

Hey @vbxcoder, it was just a guess about the problem we were facing. Later on faced same for the PDFs with smaller font size or if there is no text on the page and just an image. But it was not a problem with no. of pages.
