Burn subtitles into a video

Upload a video plus a subtitle file (.srt, .vtt or .ass) and download the video with subtitles permanently rendered into the picture — they show on every player and platform.

Which files do I add?

Exactly two: the video and the subtitle file. The subtitles are drawn into the frames, so timing comes straight from the subtitle file.

What's the difference to soft subtitles?

Soft subtitles are a separate track a player can switch off — but many platforms ignore them. Burned-in subtitles are part of the image and can never be lost, though they also can't be disabled.
