TDL

TDL is a toolkit developed in Go for Telegram that acts as a downloader with extended capabilities. It uses minimal system resources and operates at higher speeds than official clients through full bandwidth utilization. It allows downloading content from protected chats, forwarding messages with automatic backup and route configuration, uploading files to Telegram, and exporting messages, members, and subscribers to JSON format for data analysis and backups.

• Single-file startup. The program runs from a single binary file without requiring complex installation or additional system dependencies. This feature simplifies deployment in different environments and maintains portability across operating systems.
• Minimal resource consumption. Optimization of RAM and processor usage during download and data processing operations. The architectural design prioritizes efficiency over energy consumption and computational load.
• Bandwidth maximization. Implementation of parallel download algorithms that utilize the full capacity of the available internet connection. Data transfer is performed through multiple simultaneous connections with dynamic buffer adjustment.
• Superior performance to official clients. Measured download speeds that exceed those obtained with official Telegram applications due to the removal of visual processing layers and specific optimizations for file transfer.
• Download from protected chats. Ability to access and download content from conversations with automatic saving restrictions, by authenticating directly with Telegram servers using valid user credentials.
• Forwarding with automatic backup. Message transfer system between chats that includes failure recovery mechanisms and multimedia content replication. The function detects interruptions and resumes operations from the point of failure.
• Message routing configuration. Establishment of custom rules for message addressing during bulk forwarding operations. Allows filtering by content type, date, sender, or specific keywords.
• Upload files to Telegram. Transfer of files from the local system to Telegram chats, channels, or groups. Supports all file formats allowed by the platform with visible upload progress.
• Export messages to JSON. Complete conversion of conversation history to structured JSON format for external processing. Includes metadata such as timestamps, unique identifiers, and sender information.
• Export members and subscribers. Extraction of complete participant lists from groups and channels to JSON format. Contains profile details, join dates, and privilege levels when available.
• Batch processing. Execution of bulk operations on multiple chats or channels through scheduled task configuration. Manages work queues with configurable prioritization and limits.
• Flexible authentication. Multiple account verification methods including QR code, phone number, and application tokens. Maintains active sessions with automatic credential renewal.

TDL development began in 2023 as a personal project to overcome functional limitations in existing Telegram clients. The creator iyear conceived the tool for specific data management needs on messaging platforms. The implementation was carried out entirely in the Go language (Golang), chosen for its efficiency in concurrency and ability to generate standalone binaries.
