From a video to a subtitled video

Most subtitle jobs follow the same path. You have a video and need words on it; you get a first draft of the subtitles, correct the wording and timing, choose how they look, and render a copy of the video with the subtitles drawn into the picture. The guides below are grouped by the step or situation you are in, so you can jump to the part that is giving you trouble: a format your phone produced, a platform whose buttons cover the bottom of the frame, a language written right to left, or an SRT file that won't line up.

If you only need a subtitle file to upload to YouTube or a video player, the AI subtitle generator produces SRT and VTT files directly. The editor on this page is for when the subtitles should be visible in the video itself, or when you want to check and polish them against the picture first.

What runs on your device and what doesn't

The editor, the preview and the render all run in your browser tab, so the video file is never uploaded. The one step that uses a server is AI subtitles: when you ask for them, the browser extracts the audio and sends only that, and it is deleted after the subtitles come back. Importing an SRT or VTT file or typing the subtitles yourself involves no upload at all. How private translation works describes the server side in detail.

Add subtitles to a video

Ways to put subtitles on a video you already have: automatically, by hand, on any computer.

Burn, embed and hardcode

Make subtitles part of the picture so they show on every player, and deal with subtitles that are already burned in.

Subtitle and caption generators

Generate captions from speech for a specific kind of video, then edit, style and export them.

Edit and customise subtitles

Fix words, timing, size and position, and preview the result on the video.

SRT and VTT workflows

Turn subtitle files into captioned video, and create, check, fix or convert the files themselves.

Subtitles for social platforms

Layouts and workflows for the apps your video is going to, from Shorts to WhatsApp Status.

Video formats

Format-specific notes for the files the editor opens: MP4, MOV, WebM, MKV, M4V and more.

Frequently asked questions

Do I need an account to use the subtitle editor?

No. Loading a video, editing, styling, rendering the MP4 and exporting SRT or VTT need no account. Only AI subtitles ask you to sign in, because they use credits.

What does the finished file look like?

An MP4 at the same resolution and frame rate as your video, with the subtitles drawn into the picture and no watermark, plus SRT and VTT files if you export them.

Which page should I start with?

If you are new to this, start with adding subtitles to a video. If you already have an SRT file, start with SRT to MP4. If your video is for one app, open that platform's page.
