Since non-secret chats and files are stored in the cloud, you can access them from any device by logging into your account. You will never have to worry about on-device storage or losing important files, but the trade-off is that you lose a bit of privacy and security. Tap your profile picture here to see everything you've uploaded in the past.

While you can receive/send files irrespective of their type and size, you can disable automatic media download and auto-play media to save mobile data. This way, you can also avoid downloading unnecessarily large files. Open Telegram app -> Settings -> Privacy and Security. Whether you no longer want to let redundant chats clutter the precious storage of your device or wish to shield your personal chats, the auto-delete timer is for you. When you set an auto-delete timer for a specific Telegram chat, all of its content including images, videos, and documents are automatically deleted after the timer expires.
