Wanted to export all my Telegram chat data, motivated by the recent news. So you would expect that this works like with most services - you request your data, they compile an archive server-side and send you a link a while later. Nope! It all goes client-side via the Telegram client.
I tried exporting all my chats including media first, but that just got slower and slower with each file, until it just got stuck on a 61 kB photo over night.
