Generate subtitles from spoken audio or paste your own SRT. Download a subtitled video, an SRT file, or a VTT file.

By JayMiOffice AIUpdated October 24, 2026

Decide where the subtitles will be used before you process the video. Burn them into the picture for a video export, or keep a separate file for a player or editing workflow that accepts subtitles.

How It Works

Step 1Start with speech or your own subtitles

Step 2Choose how the words leave the tool

Step 3Translate when you need another language

Start with speech or your own subtitles

Upload one MP4, WebM, MKV, AVI, or MOV file up to 500 MB. Choose Speech Language, or leave it on Auto-Detect for automatic subtitles.

To supply your own text, paste it into Custom SRT (optional — leave blank for auto-generate). Automatic subtitles need a video with audio; for a silent video, provide your own subtitle text.

Choose how the words leave the tool

Output choice	Download	Use it when
Burned Into Video	MP4 video	You want the words included in the video picture.
SRT File	SRT subtitles	Your player or editor accepts a separate SRT file.
VTT File	VTT subtitles	Your destination accepts a separate WebVTT file.

For burned subtitles, open Advanced Options to choose Font Size, Font Color, and Position. Position offers Bottom or Top.

Translate when you need another language

Under Advanced Options, use Translate Subtitles to choose a target language, or leave Original Only selected. When translating custom SRT, set Speech Language to its source language; Auto-Detect is not accepted for that combination.

Select Process, then download the result. Read through names, numbers, and specialist terms, and check the timing against the spoken audio before publishing.

Automatic subtitles require audio. You can paste your own SRT for a video without audio.

Yes. Open Advanced Options and choose Bottom or Top under Position. Check the result against any titles already visible in the video.

Subtitles usually convey spoken words. Accessibility captions can also identify speakers and meaningful sounds, such as an alarm or laughter. Review whether those details are needed for your audience instead of assuming speech transcription alone covers everything a viewer needs.
