While there isn't a feature
for automatically exporting a conversation,
you can save an entire iPhone text conversation
for later review and enjoyment using a few workarounds.
Let's go over three ways
you can save a text conversation on your iPhone,
plus a bonus method if you have a Mac computer as well.
Open your messages app.
Open the conversation you want to save.
Press and hold on one of the text bubbles you want to save
and then press "More."
Here, you begin selecting all the parts
that you're going to share in order to save it.
After selecting all the parts you want to share,
press the arrow button.
This will pull up a new message window.
You can share to a phone number or email address.
This is just a transcript
and does not keep the original message bubble format.
Another option is to take screenshots of the conversation.
To take a screenshot,
have the part of the conversation you want to save
visible on the screen.
Press the side button and volume button at the same time.
This will save a screenshot.
Scroll up or down to get more of the conversation.
Take another screenshot.
Repeat this until you have images
of all the parts you want to save.
Another option is to screen-record the whole conversation
to review later.
With the conversation pulled up on your phone,
pull down your control center
from the upper-right corner of your phone,
press the screen-record button,
and then return back to the conversation.
Starting at the top,
scroll down as you're reading it.
Once complete, return back to your control center
and stop the recording.
Now you have a video
that saves in your photos of the conversation.
A bonus option is to use a Mac computer
and open your messages app on it.
Pull up the conversation you want to save.
Then click "File."
Then click "Print."
Here is your conversation.
Side note: Images will not be printed.
At the bottom, you can click "PDF," then "Save as PDF."
This will save a PDF of the conversation.
