Telegram File Converter Bot

Your personal file assistant. This workflow powers a Telegram bot. When you send a PDF document to it, the workflow uses a 'Read Binary File' node followed by an 'Edit Image' or OCR node to process the document. It then sends the converted results back to you as a message or new document.
