SRT File Generator

Q: What media formats can I upload?

You can upload MP3, WAV, MP4, MOV, WebM, OGG, FLAC, M4A, and most other common audio and video formats.

Q: Does it work with YouTube?

Yes. YouTube Studio accepts SRT files directly. Upload your video, go to Subtitles, and import the .srt file generated here.

Q: What is the difference between SRT and VTT?

SRT is the most universally supported format — it works with video editors, players, and platforms like YouTube and Netflix. WebVTT is web-native and supports additional styling, but SRT is the better choice for compatibility across desktop editors and players.

Q: Can I edit the subtitles after generating?

Yes. After generation, open the project in the Karadeo editor to fix words, adjust timing, or add visual elements. You can also export as VTT, LRC, ASS, or TTML from the editor.
