Give each picture its own page with this JPG to PDF tool, upright and without location data. A photo to PDF file is just those pictures, in the order you set.
Files stay on this device. Nothing is uploaded.
Phones often save a photo sideways and add a note saying which way is up. This page reads that note and places each photo upright, so you rarely need to turn anything by hand.
Pick US Letter, A4, or Match the picture. Match the picture uses the photo's own size, so nothing is cropped. Keep the pictures until you have opened the result.
