How to Merge Multiple Images to a PDF

Perhaps you have a selection of images that you would like to convert into a single PDF. In DEVONthink, there is a simple tool that does just that. Here is, how it works.

  1. Get images into your database.
  2. Select the images.
  3. Choose Tools > Merge Images.

That’s it, you now have a newly created PDF in your database. Simple!

However, there are a few things to consider…

  • The sort order of the images matters. They will be merged top to bottom. If you need a specific order, use View > Sort > Unsorted, then drag the documents into their positions before the merge.
  • In Tools > Inspectors > Thumbnails, you can drag the thumbnails of the merged PDF into any order.
  • Merging retains the originals. If you don’t want to keep them, hold the Option key when opening the Tools menu, and you’ll see the command is Merge & Delete Images.

As a bonus tip, if you need a searchable PDF and you’re running the Pro or Server edition of DEVONthink, run Data > OCR on the resulting PDF document.
