Pdf from Kindle to searchable PDF

Dramatically increased size of PDF after OCR

I’m using Office version to convert Scanned PDF (about 30-50 MB) to PDF+Text to make them searchable. However, after the process, the resulting PDF is about 3x size! I did for 2 of my zillion scanned PDF and found 44 MB to 150 MB and 32 MB to 120 MB… I know embedding text will increase the size, but not 3x or even more! I tried PDF Toolkit to reduce the size but seems I only can do it losing quality, that is a thing I don’t want. What I wonder is the 44 MB PDF size has the same visual quality…
