Combine batch of images into a PDF

#1 Post by webfork » Sun May 31, 2020 9:33 am

There are several reasons you might want to do this:
  • Combine a bunch of image scans into one file
  • Easily convert lots of images to text
  • Convert screen captures of DRM-protected content into a PDF file you can actually read (one of my friends has been having great difficulty with Adobe book system lately, so I tried to spend some time on possible ways around that).
Probably the easiest method is the Multi PDF Merger program or PDF shaper, but neither program gives you much control over the output.

What follows is a more manual process, but one that gives a bit more control with the output:

Steps
  1. Open LibreOffice Impress (presentations tool)
  2. From the Slide - Properties menu, select a page size and rotate to a portrait view:

    Image

    Image

    _
  3. Import images using "Insert > Picture > Photo Album", and then export to PDF for the same effect
For any text content, open in in PDF XChange to use the included OCR program.

Other notes

This process also works (with mixed results) by opening the PDFs in the Draw program, copying all thumbnails, and pasting them into Impress

Thanks for your tutorial, webfork.

When I had to convert several images into PDF, I used Irfanview with their PDF plugin to export an image to a PDF file one-by-one. Then I used PDFTK Builder to merge several PDF files together.

There might be a way to batch-convert images to PDF in Irfanview though, but I preferred going through each conversion manually to fine tune the settings.
is it stealth? ;)

Also an excellent program.

I didn't think to check graphics viewers / editors. Here's two:
  • nomacs and it's batch conversion program -- there's TIFF but nothing for PDF.
  • FastStone has a PDF export but it's (like your Irfanview test) a PDF per image, no combine option:

    Image

    ... but the output is sized to whatever the image was (no page borders), which is probably better than my system.

SwiftPDF does exactly what you want, I think. Despite its age, it works on Win 10. It defaults to 1 image per page, but you have some control over size by using page size and margins.

Looks like a good program, Cornflower. Thanks!

I'll have to remember this thread the next time I have to batch convert a bunch of images into one PDF!

Can also be done with Image to PDF
Also looks great. Here's the thread discussing Image to PDF.

Great responses, thanks hamasaki and freakazoid.

There are some gems mentioned by FileHandler in that thread.

He mentions i2pdf and ImBatch.

I think i2pdf looks like another great solution!

webfork, you already had the solution: FSViewer can not only convert every image to single PDF, but a whole bunch of images into one single PDF.
Go to "create" > "multipage builder"
Interesting: when saving a single image as PDF, the "options" button is greyed out, but if you use the multipage builder, you can set the quality, the dpi and you can batch resize the images before writing the PDF.
