Extract Subtitles from Video Free — SRT Extractor

MKV and MP4 files often contain embedded subtitle tracks -- especially media downloaded from streaming services, Blu-ray rips, or fan-subbed content. Extracting these subtitles as SRT files lets you translate them, edit them, or use them with a different video player.

MiOffice extracts embedded subtitles in your browser using FFmpeg WebAssembly. No upload, no signup. The SRT file is generated locally on your device.

Extract vs Generate Subtitles

Why Extract Subtitles?

• --Translation: Extract subtitles, translate the SRT file, and use it with a different language.
• --Editing: Fix typos or timing issues in existing subtitles.
• --Format conversion: Extract from MKV before converting to MP4, since embedded subs are lost during conversion.
• --Accessibility: Provide separate subtitle files for users who need them.
