Moving pictures with the best quality

A friend has asked me to print a picture which originated with her brother in another state. Phase One was him sending the JPG to her via Text and her sending it on to us via Signal. Both of these, I believe, do image compression, so we have asked for it to be resent using email … based on the (mis?)belief that email encodes for transmission, but doesn’t compress or otherwise alter the image. Right?

So, other than verifying the above, the question is what to use and what to avoid in order to preserve image quality.

  • I have read about selecting High instead of Standard in Media Quality in Signal, but that is still going to do some compression.
  • I have read about using File instead of Photos and Videos when adding the image in Signal, but not tested it yet,
  • I have thought about sharing via some cloud storage, but am unsure what to do. A couple of us (not me) use iPhones, if that helps.

Suggestions?

Drop it in a google drive and share the link to the file. Keeps it original.

I will have to see if the source of the photo has anything like this.

My only thought, not reliable, is that to attach it to the email as a file, rather than embed it as a picture. If that even makes sense.

Always! Embedded might work for psycho effects, but attach for sure to send the file. I’ve always thought that was loss free, but now I am less sure.
