File mode  write and binary  Since you are writing a  jpg file  it looks fine    But if you supposed to read that jpg file you need to use  rb   More info     On Windows   b  appended to the mode   opens the file in binary mode  so   there are also modes like  rb    wb     and  r b   Python on Windows makes a   distinction between text and binary   files  the end-of-line characters in   text files are automatically altered   slightly when data is read or written    This behind-the-scenes modification to   file data is fine for ASCII text   files  but it   ll corrupt binary data   like that in JPEG or EXE files

The wb indicates that the file is opened for writing in binary mode   When writing in binary mode  Python makes no changes to data as it is written to the file  In text mode  when the b is excluded as in just w or when you specify text mode with wt   however  Python will encode the text based on the default text encoding  Additionally  Python will convert line endings   n  to whatever the platform-specific line ending is  which would corrupt a binary file like an exe or png file   Text mode should therefore be used when writing text files  whether using plain text or a text-based format like CSV   while binary mode must be used when writing non-text files like images   References   https   docs python org 3 tutorial inputoutput html reading-and-writing-files https   docs python org 3 library functions html open

That is the mode with which you are opening the file   wb  means that you are writing to the file  w   and that you are writing in binary mode  b    Check out the documentation for more  clicky
