Frequently Asked Questions
How do I extract SRT from MKV files online?
Our online subtitle extractor makes it easy to rip subtitles from MKV. Simply upload your video, and the tool will automatically detect all embedded subtitle streams. You can then select specific tracks and export them as SRT files or WebVTT format instantly.
Is my video uploaded to a server?
No. This is a 100% private subtitle extractor. We use WebAssembly (FFmpeg.wasm) to process your files directly in your browser. Your video never leaves your computer, making it the most secure way to extract subtitles from video without compromising your privacy.
Which video formats are supported?
You can extract subtitles from MP4, MKV, MOV, and many other containers. As long as your browser and the underlying FFmpeg engine can read the file, you can extract embedded subtitles (soft-subs) into standalone text files.
Can I extract multiple subtitle tracks at once?
Yes! Our subtitle ripper allows you to select multiple languages or tracks from a single video file and export them all in a batch, saving you time during video localizations or transcriptions.
