Burn subtitles into a video
Embed the SRT you made by transcribing with Transcriber or translating into the picture itself (hardsub). It shows up on social media and in stock phone players that cannot read subtitle files. Video and subtitles never leave your device.

How to use
- 1
Add the video and subtitles
Drop the video and choose an SRT or WebVTT file under “Subtitle file”. The same subtitles can be burned into several videos.
- 2
Choose the look
Under “How to embed” choose burning in or a subtitle track. For burning in, set the position (bottom / top), text size, color and legibility (black outline / translucent bar). Long lines shrink automatically to fit the width.

Run and save
Every frame is drawn and re-encoded, so it takes time proportional to the video length. The exported video shows the subtitles in every player.
Supported subtitles and how they are drawn
Reads SRT and WebVTT. The encoding is detected automatically: UTF-8, plus Shift_JIS, which is common for Japanese files. Formatting tags such as italic and bold, and positioning codes in curly braces (such as an8), are removed, and multi-line cues are drawn as multiple lines. When cues overlap, the one that started first is shown.
The text is drawn onto the frames and the video is re-encoded, so a second compression is unavoidable. With “Quality” at High or above the difference is barely visible. Fonts are Noto Sans JP (Japanese) and your device's fonts; font settings or ruby inside the subtitle file are not supported.
Frequently asked questions
Are the video and subtitles uploaded?
No. Parsing, drawing and re-encoding all happen inside your browser.
The text is garbled
UTF-8 and Shift_JIS are detected automatically. For other encodings (such as EUC-JP), re-save the file as UTF-8 in a text editor first.
The subtitles are out of sync
The times in the subtitle file are used as they are. If you trimmed the start of the video, subtitles made for the original will be offset; adjust the times in the subtitle file.
Can I embed them as a soft subtitle track instead?
Yes. Choose “Add as a subtitle track” under “How to embed”. The video and audio are copied as they are and the subtitles are stored as a WebVTT track in an MKV file (no re-encoding, nearly instant). VLC, Windows Media Player and most Android players can toggle them, but the stock iPhone player and social media sites will not show them. Subtitle tracks cannot be added to MP4.
Help us improve the service
If a conversion fails, sending us the circumstances helps us track down the cause. Knowing which devices and formats fail most often, and how long processing takes, lets us revise the supported formats and fix the bugs behind them. If you don't mind, leaving this on is a real help.
What is sent
The tool you used and the settings you chose (output format, quality, etc.), your device specs (GPU, memory, core count), the input format with a rough size, how many files succeeded or failed and how long it took, and the error type and details when something fails.
What is never sent
The files themselves, file names, text, subtitles or prompts you add to a video, and IP addresses. The data goes only to this site's own server, never to a third-party service.
