Well, a new tool to play with, thanks to Herbert's

Ok. I created 1000 random bytes with OpenSSL, converted
them with az, with a line length of 50 characters set.
Then the file was opened in LibreOffice, with the settings
of 16 pt, Liberation Mono font and saved as .pdf. With
these settings, 2000 characters fit exactly in an A4 page.
To send a Telefax to my Fax machine I used an online
service, where I have a paid account.
Once the Fax was received I scanned it with 200 dpi and
saved it as .png. For OCR translation I used Boxsoft Free
OCR, for Windows, because Tesseract gave me more errors
in the past. I only had one error in one line, which showed
at the beginning a dot and space, which I removed manually.
Again I used az to decode the file and a diff showed no
differences in the binaries.
Here is a URL with the files, in case someone likes to look
at them:
