How to use img2pdf module as a module
I am creating a tiny Python 2.7.9 script that takes a list of JPEG images as input and outputs a PDF. I have been working for a couple of hours but cannot find a solution:
- I tried pypdf but it says I don't have PIL, although I do.
- I tried Reportlab but the page size is bigger than the image itself and I couldn't find a way to fix it. It's also hard for me ...
- I tried img2pdf but couldn't figure out how to use it.
I am really tired of all these libraries and I am looking for a good solution . Good means:
- How pythonic possible
- size page size to image size
- Support for a large number of images (maybe even 500)
- easy enough
If you can help with the modules I've already tried / code examples that would be great. Also, if you have any experience with the module, I would be glad if you could share it.
Edit:
As suggested in the comments, I decided to give img2pdf one more try. I am using the following code from the official GitHub README :
import img2pdf
pdf_bytes = img2pdf('test.jpg', dpi=150)
But it throws an exception: `TypeError: 'module' object could not be called
Does anyone know how to use img2pdf as a module for multiple images? `

Nothing in the GitHub code tells me that this module is callable. It is possible that there is an error in the readme; they are for an example of using the function convert
. Try this instead:
import img2pdf
pdf_bytes = img2pdf.convert(('test.jpg',), dpi=150, x=None, y=None)
In the source code, this function requires positional arguments x
and y
:
def convert(images, dpi, x, y, title=None, author=None, creator=None, producer=None,
creationdate=None, moddate=None, subject=None, keywords=None,
colorspace=None, verbose=False):
But as long as you provide an argument dpi
, it is set to the default case, which makes it look (at least to me), since both x
and y
assumed optional arguments:
if not x and not y:
pdf_x, pdf_y = 72.0*width/ndpi[0], 72.0*height/ndpi[1]
The package you received on PIP is not necessarily identical to the GitHub code. You can try it without supplying x
and y
as arguments convert
, and - or even better, find the source file on your own machine and see for yourself.
