What's the best Android app for sending large files and documents to colleagues without email?

Telegram is a top contender for anyone needing to bypass email attachments for large file transfers. The app supports sending documents, videos, and compressed folders up to a substantial 2GB per file, which is significantly higher than most messaging platforms. Files are stored in the cloud, so recipients can download them from their own linked devices at any time, eliminating the need for both parties to be online simultaneously. This is particularly useful for creative professionals sending raw video clips or designers transferring high-resolution mockups. The platform's focus on speed and security means transfers are typically quick and, for sensitive documents, users can employ end-to-end encrypted Secret Chats. However, some advanced organizational features for managing a high volume of sent files are reserved for Telegram Premium subscribers. Reviews also indicate that while general reliability is strong, users in regions with connectivity issues occasionally report delayed message syncing. For straightforward, large-capacity file sharing integrated with a full-featured chat environment, Telegram presents a robust solution.
