How to merge png files into a single PDF... by using javascript

Yes it is, but there is a much easier way using the "Create PDF > From multiple files..." menu item.But if you really want to use JavaScript it's a bit awkward, but it can be done. First, this has to be written as an automation script. The code itself will need to be placed in a privileged function in a folder level script.

Use the "app.openDoc()" function with the "bUseConv" option. You'll need to run this on every png file, then use the "doc.insertPages()" function to place them all in the same file.

There's lots of picky details to this process, you can find most of what you need in the Acrobat JavaScript Reference.

My hearty thanks for you help. It is so useful.

Yep, I known these operations are a bit awkward, but merging files into a single pdf is just a part of my js code's mission.

I will try it out myself right now.

Thanks again.
