I would like to transform a PDF document into a jpg doc
We don't have this capability in Acrobat Mobile. It's probably easiest to just take a screen capture of the document on your phone.
Thank you for reaching out. We have "Export PDF to Image" feature in 22.02.00 or above.
If you have the premium subscription, please give it try.
#1. Tap "..." next to the PDF that you want to export images
#2. In Context board, select "Export PDF" (see Step2.PNG)
#3. In Export PDF screen, select "Image" tab, then choose the image format following by hitting "Continue" button (see Step3.PNG)
#4. In Select page screen, choose pages or tap "Select all" for all pages (see Step4.PNG)
#5. Choose either "Share Images" to yourself or "Save to Photos"
Note, if choosing "Save to Photos", the output images will be saved into "Adobe Acrobat Reader" album in "Photos" app on your device.
Hope this help,
