Online sup to srt converter
Sup files are subtitle files that contain pictures of text.
This tool uses Tesseract OCR to read the text in the pictures, and converts the file to srt. You need to select the language of your sup file for Tesseract to work correctly. If you're not sure what language your sup file is, just give English a try and see if it works.
This tool supports three different sup formats: bluray, hddvd and normal dvd.
