Burned-in versus soft subtitles
Soft subtitles live in a separate track that the player can switch off — great for streaming, useless when the platform ignores them. Burned-in captions are painted into the pixels, so they survive every re-upload, autoplay-muted feed and screen recording. That is why social video almost always burns them in.
SRT and VTT both work
Paste or drop either format. Timestamps are read as written, so if your subtitles are already in sync with the video they stay in sync. Styling tags inside the file are ignored — the look is controlled by the options here instead.
Frequently asked questions
Which subtitle formats can I use?
SubRip (.srt) and WebVTT (.vtt), the two formats almost every subtitle tool exports. You can also paste the raw text if you do not have a file.
Is my file uploaded?
No. Everything is parsed and processed inside your browser — the file never leaves your device.
