If you download your Twitter archive it arrives wrapped as a static HTML page, which is not very useful for doing anything with, and worse: it requires the original account to be still active to do useful things like enlarge the images since they use t.co links.
So here's a Python script to convert a Twitter archive to markdown or other formats: https://github.com/timhutton/twitter-archive-parser
Now you can archive your tweets in any way you want.
@timhutton coole Idee und Sache 👍 👏🙏
@timhutton I just did my archive download but had no idea how limited it was, thank you for this!!
@timhutton this is very useful advice. I got my archive a couple weeks ago and yes it is a pain to work with.
