Telegram lets users send media and documents in chats, groups and channels. What happens after you receive a file depends on your client settings, device storage and the type of conversation. Downloading a file does not prove that it is safe or authentic. Check the sender, source and file type before opening or installing it.
Share only what the recipient needs
Before sending a photo or document, check what it contains. Images may reveal faces, addresses, screens or locations. Documents can include comments, names and revision history. Confirm the chat and recipient before sending, especially in a large group or channel.
For work or sensitive information, follow the organization’s sharing and retention rules. Recipients may save or forward files, so avoid sending material that should remain accessible only to you. A Secret Chat has different device-specific behavior, but it does not prevent another participant from photographing or copying information.
Control automatic downloads
Telegram clients may offer automatic-download settings for media based on network connection or chat type. Review the current Data and Storage controls on your device. Decide whether large videos, documents or other attachments should download on mobile data, Wi-Fi or roaming.
Automatic download is a convenience setting, not a security scan. Use Telegram file download safety before opening unexpected archives, installers or documents.
Manage cache and local copies
Telegram may retain local cache to make media easier to access. If storage is low, review the app’s cache controls and device storage settings. Clearing cache is not the same as deleting an account or chat, but local availability can change. Preserve files you need before clearing app data or uninstalling.
See the Telegram cache guide for cautious steps and the difference between device storage and cloud chat access.
Understand device and chat differences
Cloud chats are designed to sync across signed-in devices. Secret Chats are device-specific and do not sync the same way. A file or message available on one device may not be available from another in every context. Before replacing a phone, read Secret Chats explained and check local files you still need.
Frequently asked questions
Does Telegram scan every file for safety?

Can I stop videos from downloading automatically?
Review the current Data and Storage settings in your Telegram client and choose the networks and media types that fit your needs.
Does clearing cache delete my cloud chats?
Cache controls and chat deletion are different actions, but options can vary by client. Read the confirmation carefully and preserve local files before clearing app data.
