Does anyone have a tool or know of the pixel conversions for a JPG image point to PDF document location?

Images are images, regardless of the file format they are all an array of pixels. The PDF coordinate spaces are all measured at 72points/inch. So if you know the image location, width, and height in PDF coordinates, then it's a straight forward conversion to find the location of a pixel.
For example, to get the horizontal coordinate:
xPDF = xImageCoord + xPixel * ImageWidthPDF/ImageWidthPixels
Of course, how this is done depends on the context. What are you trying to do?
I would like to insert highlighted text from JPG images from Microsoft Azure Computer Vision OCR API.
Thanks for letting me know on the dpi for PDF.
I may need to create a formula.
