Pick your video and a subtitle file, or paste the text, choose the size, color, style and position, and get a video with the captions drawn into the picture. The video never leaves your device. It is read and saved by your browser, so there is no upload, no queue and no copy on a server.
Most people watch social video with the sound off. Burned-in captions show on Instagram, TikTok, WhatsApp and anywhere else, with no subtitle file to keep with the video.
How to add subtitles to a video
- Drop your video on the box above.
- Press “Choose subtitle file” and pick an SRT, VTT, ASS or SBV file, or paste the text.
- Pick the size, color, style and position. Shift the timing if the lines are early or late.
- Press Add subtitles and download the video.
Burned in or separate?
Burned-in subtitles are part of the picture: they always show, can’t be turned off and look the same everywhere. A separate SRT file can be switched on or off, but many apps ignore it. For social posts, burning in is the reliable choice.
Timing off?
If every line comes too late, type a negative shift such as -1.5 to show them earlier; a positive number shows them later.
Styling from ASS files
The text and timing of ASS files are used; their fonts, colors and positions are replaced by the style you pick here.
Questions
Can I make subtitles from the speech?
Not yet. The tool needs a subtitle file you already have.
Which languages work?
Any language. Long lines wrap automatically, including Chinese, Japanese and Thai.
Can I edit the text?
Use “Paste text instead”, paste the subtitle file, and edit it there.
