Purpose and Audience

This n8n workflow creates an automated Telegram bot that adds watermarks to images. When users send photos to the bot, it automatically processes them by applying a logo overlay and returns the watermarked version. The workflow is designed for content creators, businesses, or individuals who need a quick, automated way to brand their images without manual editing software.

1. How It Works

The workflow operates through a series of connected steps:

• Message Reception: A Telegram trigger listens for incoming messages from users
• Image Validation: The system checks whether the message contains a photo; if not, it sends a friendly error message asking the user to send an image
• Image Retrieval: When a photo is detected, the workflow fetches the file path from Telegram’s servers and downloads the full-resolution image
• Upload & Watermarking: The downloaded image is uploaded to ImageKit.io, where a transformation is applied to overlay a logo watermark at 70% opacity
• Delivery: The watermarked image is automatically sent back to the user via Telegram

The entire process happens in seconds, providing users with instant watermarked images through a simple chat interface.

2. Who Is It For

This workflow is ideal for:

• Social media managers who need to quickly brand images before posting
• Small business owners protecting their product photos with company logos
• Content creators who want an easy way to watermark their work on the go
• Marketing teams requiring consistent branding across visual content
• Photographers offering quick preview watermarking for client galleries
• Anyone looking for a mobile-friendly, automated watermarking solution without installing desktop software

The bot requires minimal technical knowledge to use—simply send an image and receive it back watermarked—making it accessible to non-technical users while being built on a powerful automation platform.
