How do I convert a GSRT subtitle file to MP3?

Upload your GSRT file, choose an output voice and MP3 bitrate (e.g., 320kbps), then click Convert. We'll extract the subtitle text, generate speech for each subtitle line, and encode the audio into a single MP3 file for download.

Why convert GSRT to MP3 instead of keeping the subtitle file?

GSRT is a text-based subtitle format that requires a video player to render; it cannot be played on its own. Converting to MP3 creates a portable audio file that works on any device, including phones, MP3 players, and car stereos. It's also much smaller than a video file and lets you consume subtitle content hands-free.

How are GSRT timing and formatting preserved during conversion to MP3?

Subtitle text is read aloud sequentially, using GSRT timing tags to pace the speech, so dialogue matches the original sequence. Subtitle styling (colors, positioning) is discarded as it has no audio equivalent. The MP3 output encodes speech at your selected bitrate (up to 320kbps) with optional voice pauses for clarity.
