How to merge multiple image files into one pdf file with page and its original size for every image?

Solution 1:

Solution:

I found a tool that will do exactly what you want (one PDF, pages the size of images). You can find it at https://smallpdf.com/jpg-to-pdf. Upload your files, choose 'auto' as the size, choose 'no margin' as the margin and you're good to go.

Solution 2:

Select and Open all images in Preview.

Select the File > Print dialog in Preview

Preview Print dialog

Set as showing, or modify to your desire.

Select "Save as PDF" (bottom left corner)

Result in PDF (I only used 2 images in this case) but you will have individual PDF pages for each.
