## Browser Subtitle Converters
Convert supported text subtitle formats to SRT, VTT, TXT, DOCX, or PDF locally in your browser. This cluster does not perform image or video subtitle OCR.

All English cluster pages are indexable. Spanish and Brazilian Portuguese also index the hub, VTT to SRT, and SRT to TXT; other translated direction pages remain available but are intentionally not indexed.

Indexable paths by locale:
- `en`: `/subtitle-converter`, `/srt-to-vtt`, `/srt-to-word`, `/srt-to-text`, `/srt-to-pdf`, `/vtt-to-srt`, `/vtt-to-word`, `/vtt-to-text`, `/vtt-to-pdf`
- `es`: `/subtitle-converter`, `/srt-to-text`, `/vtt-to-srt`
- `pt-BR`: `/subtitle-converter`, `/srt-to-text`, `/vtt-to-srt`

- [Subtitle Converter](https://whisperweb.dev/subtitle-converter) — Choose a text subtitle conversion workflow.
- [SRT to VTT](https://whisperweb.dev/srt-to-vtt) — Convert SubRip captions for WebVTT players.

## Subtitle Generation and Export

Last reviewed: 2026-09-03.

- [Subtitle Generator](https://whisperweb.dev/generate-subtitles) — Turn owned or authorized audio or video into editable timed cues. Free generation runs locally in the browser; review text and timing before exporting SRT or VTT.
- Source-language pages transcribe speech into subtitles in the same language.
- Source-to-English pages use Whisper translation mode and produce timed English subtitle text.
- A direct public media-file URL may be used when the browser can fetch it. Ordinary YouTube and Bilibili watch-page URLs are not supported importers.
- Whisper Web does not claim human proofreading, subtitle burn-in, arbitrary target-language translation, account connection, or automatic platform publishing in this workflow.

### Localized Subtitle Generator Matrix

The 5 source-language pages and 3 source-to-English pages below are localized for `en`, `de`, `es`, `fr`, `it`, `nl`, `pl`, and `pt-BR` (64 locale URLs total). They use the same browser subtitle generator with a real source-language preset; English slugs are retained as stable canonical paths. Non-English URLs use `/{locale}/subtitle-generator/{slug}`; the complete 64-URL list and page descriptions are in [llms-full.txt](https://whisperweb.dev/llms-full.txt).

- [English subtitles](https://whisperweb.dev/subtitle-generator/english-subtitles)
- [Spanish subtitles](https://whisperweb.dev/subtitle-generator/spanish-subtitles)
- [French subtitles](https://whisperweb.dev/subtitle-generator/french-subtitles)
- [Japanese subtitles](https://whisperweb.dev/subtitle-generator/japanese-subtitles)
- [Hindi subtitles](https://whisperweb.dev/subtitle-generator/hi-subtitles)
- [Japanese to English subtitles](https://whisperweb.dev/subtitle-generator/japanese-to-english-subtitles)

### Platform Subtitle Guides

- [Add subtitles to YouTube](https://whisperweb.dev/add-subtitles-in-youtube) — Generate and review SRT or VTT, then upload the file manually in YouTube Studio.
- [Add subtitles to Bilibili](https://whisperweb.dev/add-subtitles-in-bilibili) — Prepare a reviewed subtitle file, then check the uploader and accepted formats available for the creator account.

These platform guides remain English-only because their query intent and supported instructions are platform-specific; they are not translated matrix pages and do not publish to either platform.
