Anyone got PDF to PDF (OCR) software

Anyone able to help out converting a PDF consisting of scanned images of text, coupled with photos, to an OCR version which recognises the text for search purposes ? It's a large document thereby ruling out the free options online.

If you have can you email me below.

Don't know if this will work but i use Google, to change word to PDF.
I only use on rate occasions and don't remember where to find in Google.

How many pages Pete?

Thanks Kevin but it's somewhat different. Nick I will send you an email

I know you don't want an online version, but if you get stuck, I use this one all the time which is really effective:

Thanks Paul but the free sites have max file sizes which this one exceeds.

1.Open a PDF file containing a scanned image in Acrobat.
2.Click on the Edit PDF tool in the right pane. Acrobat (https://docsbay.net/how-to-create-an-adobe-acrobat-file) automatically applies optical character recognition (OCR) to your document and converts it to a fully editable copy of your PDF.
3.Click the text element you wish to edit and start typing. New text matches the look of the original fonts in your scanned image.
4.Choose File > Save As and type a new name for your editable document.
