Video, GIF & Audio

Generate subtitles locally.

Turn speech in an audio or video file into timed subtitles, then export SRT, VTT or plain text.

Useful first-pass timing

The local speech model creates text and machine-generated timestamps. SRT is useful for editors and upload platforms; VTT is common for web video.

Check the timing before publishing

Automatic subtitle boundaries are estimates. Play the file through and check line timing, punctuation, speaker changes, names and any important numbers.

Local processing

The media stays in the browser while the model runs. The first transcription can take longer because the speech model has to download before it can work locally.

Useful to know

Do the job. Know what to check.

Short, practical guidance for this specific kind of task, without turning a tiny job into a tutorial marathon.

What this tool does

Subtitle generator

Generate timed subtitles locally from audio or video, then export SRT, VTT or plain text.

The tool is designed to get that one job done without making you learn a full piece of software first.

Best results

Play the exported file before you share it.

Watch the beginning and end, then jump through the middle. Make sure picture, sound, timing, crop and orientation survived.

After export, play the file in an ordinary browser or phone viewer before sharing it.

In plain English

What matters most.

For a one-off video job, the useful test is whether the exported file plays properly where you intend to use it.

For one-off jobs, a focused tool is usually faster than opening a full video editor.

File size & formats

Large videos need more patience.

What can I use?

Choose a video format your browser can open. Browser-based video exports use WebM where the tool needs to re-encode a clip.

Is there a size limit?

There is no extra OutMonkey file-size cap in these browser tools. Your device memory and browser are the practical limit, so very large or long videos can be slow or fail.

If the file is huge

Shorter clips and ordinary phone-sized videos are the safest fit. Keep this tab open while a video is processing.
