failed to convert

lmh · 12-26-2021, 08:05 PM

I have the most up to date version of Calibre and up until this evening I have never had any issues.
However while trying to convert a book from epub to pdf I am getting an error saying that it failed to convert.
This is the information that it shows

Spoiler:

I am not sure what all that means or how to resolve this issue. Any assistance would be greatly appreciated.

Thank You

Code:

  calibre, version 5.34.0 (win32, embedded-python: True)

... many lines deleted ...

  File "calibre\ebooks\conversion\plugins\pdf_output.py", line 255, in convert_text

I think the key there is the out of memory error and that you are currently running the Windows 32 bit version. If you running Windows x64, I would suggest upgrading calibre to it's 64 bit version which can allow use of more memory.

Yes, my computer is running windows 10 home and it is the 64 bit version. Funny how this is the first time I have ever had this problem and I have been using Calibre for a little while now. Will look for the upgrade to the 64 bit version and do so now.
Thanks So Very Much

Thank you for this insight! I was having the same problem and switching to the 64 bit version did the trick!
