FAQ
What's the difference between SRT and VTT?+
SRT is the older standard (movies/DVDs); VTT is the web standard (HTML5 video, supports styling). Both have similar structure — they differ in the separator (comma vs. period) and header (WEBVTT).
Subtitles are ahead/behind the video. How do I fix it?+
Enter +1.5 (delay 1.5s) or -2.0 (advance 2s) as the time offset. All subtitle timings shift in bulk.
How do I extract just the text?+
Pick TXT as the output. Timing info is stripped and only the dialogue is kept. Handy for ChatGPT or translators.
Can I edit the subtitles directly?+
Yes — edit the text on the left and the output updates instantly.
Does it handle large files?+
Thousands of lines process instantly. Everything runs in your browser — nothing is transmitted.
What about ASS or SSA subtitles?+
Currently SRT/VTT only. ASS/SSA carry styling info and need a different converter.
