I am looking for a tool that converts PDF into PPT files or supports any tweak to import PDF files into LibreOffice-impress, LibreOffice-Draw imports the PDF but that does not do the job. So far I am trying to use a workaround called pdftk+pdfchain to burst the pages of the PDF file into single page PDF files and then converting the single page PDF files into images using ImageMagic and importing them into a PPT slide.

Here's my take on it from personal experience. It's a two-step process - convert the PDF into single jpegs, then import the jpegs into LibreOffice Impress. It works best if the pages in the PDF are landscape already.

1.) Make sure the package imagemagick is installed (apt install imagemagick). Put your source PDF into a directory. Then in the terminal, navigate to that directory and run:

convert filename.pdf filename.jpg

This will spit out a jpeg of each page in the PDF. Move the PDF out of the directory to make step 2 easier.

2.) Open Impress. Go to Slide menu, Slide Layout -> Blank. This will remove the "Click to add title" and stuff. Then go to Insert -> Media -> Photo Album. Click add. Navigate to the directory with all your jpegs. Select all the jpegs (if you removed the PDF from the directory in step 1, just press CTRL + A to select all of them). Click Open. The next options depend on what the pages in the original PDF looked like - if they were landscape, you can probably choose Fill Screen, but you'll have to see what works best for your case.

    convert -density 600 -resize 400% filename.pdf filename.png worked for me to obtain high quality and good output resolution.

  • (For ImageMagick version 1.3.20) If your source PDF is a multi-page document, a good Step 1 above would be gs -dNOPAUSE -dBATCH -dSAFER -dGraphicsAlphaBits=4 -dTextAlphaBits=4 -sDEVICE=jpeg -r300 -sOutputFile='page-%00d.jpg' YOURFILE.pdf (as seen in a comment to the original question).

Yes, there are several ways to convert pdf to ppt: online converting services, OmniFormat (very old software), etc.

Best solution i've used so many times is Able2Extract : http://www.investintech.com/products/desktop/able2extract/convertpdftopowerpoint/. Unfortunately it's proprietary software. You get free trial for like 7 days. But it's the best by far, for both Windows AND linux.

Works in LibreOffice ver. 4.3.3.2

Idea gleaned from this post.

Open a new instance of LibreOffice Impress. Hit Ctrl-o (to commence the process of opening a file). In the ensuing Open window, go to the File type drop-down menu and select PDF – Portable Document Format (Impress) (*.pdf). Then, select your PDF file of choice.

Said PDF file should then load into Impress. You can now save the presentation in whatever format is available...but, be sure to check the finished product if saving in a PowerPoint format, as the slides MAY get corrupted along the way.
