About this tool

Reads a SubRip (.srt) file and draws each line into the picture while it is on screen, white on a dark box at the bottom. Arabic is shaped and ordered by the site's own Arabic engine and drawn from the font's outlines, so letters join and read right to left correctly on any device. The video is encoded again with your browser's own video encoder, and the sound is kept as it is when it can. A video that is turned is not supported yet. MP4, QuickTime and WebM videos; the result is an MP4. Your files stay on your device.

Adding subtitles needs a browser that can encode video and run WebAssembly in the background.

How it works

  1. Add your file from your device. Files cannot be added from a web address.
  2. Choose the options this tool offers, if it has any.
  3. Run the tool and download the result.
