Frequently Asked Questions

What subtitle formats can I export?

Whisper Web exports SRT (SubRip) and VTT (WebVTT). SRT works with creator platforms and common video editors, while VTT is designed for HTML5 and other web video players.

How do I automatically generate subtitles?

Upload a supported video or audio file, choose the spoken language, and start generation. Whisper Web turns the speech into timed cues that you can review before downloading.

Is the subtitle generator free?

Yes. Free subtitle generation runs locally in your browser for files up to 200 MB and 20 minutes. Pro adds cloud processing, longer-file workflows, batch work, and cloud history.

Can I edit subtitles after they are generated?

Yes. You can edit cue text, change start and end times, add cues, and remove cues directly on the generator page before exporting SRT or VTT.

How accurate are AI-generated subtitles?

Accuracy varies with the language, speaker, microphone, background noise, and model. Always review names, specialist terms, and timing before publishing.

Can I generate subtitles for YouTube or TikTok?

You can generate subtitles from media you own or are authorized to process, export SRT or VTT, and upload the file using the subtitle controls provided by the publishing platform.

Does Whisper Web upload my video?

Free processing runs locally in your browser, so the media is not uploaded to Whisper Web servers. Pro cloud processing uploads files when you explicitly choose a cloud workflow.

Can it translate subtitles into another language?

This generator transcribes speech in its original language. It does not currently translate, style, burn subtitles into video, or provide human proofreading.

The benefits of generating subtitles with Whisper Web

AI removes the slow first pass of typing every spoken word, while the cue editor keeps you in control of wording and timing. Free transcription runs locally in the browser, so private drafts and unreleased media do not need to be uploaded to Whisper Web servers.

After generation, review the timed cues and export SRT for creator platforms and editing software or VTT for web players. Pro is available when you need cloud processing, longer files, saved cloud history, or batch workflows.
