Question How to turn multiple jpg images into 1 pdf ebook file

I have been downloading a few manga from the internet lately and I was wondering how to turn jpg files into 1 pdf file. So each manga will have there original number per ebook.

Example the first manga I downloaded has (40) images. Which means I need to look at each image one at a time. And I need to use a image viewer app on my tablet. I prefer a free ebook reader. So I wanted to know if there is a way to turn (40) jpgs into (1) pdf ebook. And if so can I do it with this program if not could you suggest a free program that might work thank you!

By the way when I said Original number it means this the first chapter of the manga is Chapter (1) and that Chapter has (40) images including the cover art. So I want to make a PDF ebook file for each of the manga Chapters so that way each Chapter has there own ebook file. I hope this makes sense. Thanks again.

@DawnDawn88 - on Windows try IrfanView - Homepage - plugin bundle is a separate download

Click image for larger version

Or… if you put the images into a zip and add the zip to your library you will have a CBZ (Comic Book Zip) which can be viewed with a comic viewer.

Okay here is what I understand so far I can zip the chapters of this anime manga and then place the zipped folders into the calibre program and then I can convert them to pdf. Plus I don't have a comic viewer I just have the plain ebook reader on my tablet.

So my downloads folder currently has 312 manga folders from just 1 manga each folder is for a different chapter. Can I just zip each of these folders and then move them to a folder in my libraries on my computer called PDF and name the folder zipped. And then scan the zipped folder with calibre and have calibre convert each of these for me into pdf.

Is this possible then.

If so just say yes if not tell me what I can do to figure out how to turn these into individual ebooks please and thank you.

I have been using the calibre program for a while now but I have never done a job like this before with the program.

Sorry for the long winded reply I'm just still a bit new to the program. When it comes to things other then converting from amazon ebooks to pdf.

I've never needed to convert a CBZ to a PDF, and I avoid conversions if I can. That said:

I converted a CBZ to PDF with calibre using the default settings; the result was black and white images resized to fit on an A4 page - I'd call it a 'useful' PDF.

And I created a PDF using IrfanView with the same set of images with it's default settings; it didn't do any image resizing and retained the colours, to get what I'd regard as a 'useful' PDF I would need to to do some tweaking.

But, but, but… you should be able to read CBZs on your Kindle Fire directly, for example ==>> Amazon.com: ComiCat (Comic Reader/Viewer)

Have a look in the Kindle Fire forum and perhaps ask about a good comic reader there.

You can turn off grayscaling in the comic input settings in the conversion dialog.

These files are inside a folder and each of these files are JPG. And the folder types are un-zipped so do I just zip them and place them inside the Calibre I have never used the other program before. So is there a tutorial on how to do this is is there someone that can tell me how to do this please step by step.

Thank You!

A Google search on "creating a cbz file" could help. A sample site would be Create CBR CBZ File and Insert Images in Serial Order which makes it clear that the files will be read in a strict alphabetical sort order so you need to name the files image001.jpg, image002.jpg, etc.

Never mind I decided to just give it a try in calibre and it looks fine even the cover is in color for me. I didn't even tinker with anything. Simple to figure out once I knew I could use this program to do it I just gave it a try. All good for this so far.

You don't need extra programs to create a zip file, you can do it in Windows 10 File Explorer, the Zip button is in the Share tab -- I wouldn't have put it there either
