Conversion of Image into PDF

Team,

I am using Acrobat DC trail version for performing OCR.

I have different kind of ImageType to perform OCR like (TIF/JOG/PNG etc..)

I do open all images in PDF, which basically convert Image to PDF.

It sometimes open few of Image in PDF but at same time proper files are failed to open in PDF...

I have tiff files with proper resolution of 300 DPI and Proper size, but adobe not open it in PDF.

Is there any setting which allows to open/Convert all supported files in Adobe PDF  ? or any setting which helps to open proper ImageType IN PDF form.

Thanks
