SRT to TXT Converter

A simple web application that converts SRT (SubRip Subtitle) files to plain text transcripts by extracting only the subtitle text content and removing timing information and subtitle numbers.

What it does

This tool takes SRT subtitle files and converts them to plain text by:

• Removing subtitle numbers (e.g., "1", "2", "3")
• Removing timing information (e.g., "00:00:01,000 --> 00:00:04,000")
• Extracting only the actual subtitle text content
• Combining all text into a single, readable transcript

Features

• Web-based interface for easy file upload
• Real-time conversion
• Error handling for malformed SRT files
• Simple and clean output format
