How to Convert Multiple PPM Images to PDF?
1. Download and Install reaConverter
reaConverter is a standalone Windows app — download, install, and start converting PPM files in under two minutes. Built-in editing tools let you resize, crop, or watermark as you convert.
2. Load your PPM files
Start reaConverter and add your .ppm files. The software processes everything locally, so your files never leave your computer.
Use drag-and-drop, folder browser, or right-click conversion from Explorer.

3. Select PDF as output format
Select PDF from the format list. Configure page selection and output quality for your PDF files.

4. Start PPM to PDF conversion
Click Convert to start the batch. reaConverter processes files quickly and shows you the status of each one.

Once done, reaConverter shows a summary. Click 'Show converted files' to jump straight to your PDF output.
PPM to PDF: what carries over and what does not
PDF is a page format, so each PPM image is placed on a page rather than converted into something else. Two settings decide how the result looks: the DPI, which fixes how large the image sits on the page, and whether a batch becomes one file per image or a single merged document. reaConverter can do either.
