Questions

Burned in or a subtitle track: which should I choose?

Burned-in subtitles are part of the picture: they show everywhere, including Instagram, TikTok and WhatsApp, but can’t be turned off. A subtitle track keeps the picture untouched and lets viewers choose, but only players that read subtitle tracks (VLC, mpv, most TVs and media servers) show it.

The subtitles are out of sync. What can I do?

Enter a shift in seconds: a positive number makes them appear later, a negative number earlier (like -1.5). Play the video to check, then save. To change the frame rate of subtitles, use the Subtitle Converter first.

Which subtitle formats work?

SRT, WebVTT (VTT), YouTube SBV, ASS and SSA, MicroDVD (SUB) and TTML (DFXP). Italic, bold and underlined text is kept when burning in. Files in other character sets than UTF-8 are read as Western European (Windows-1252).

Is the video re-encoded?

Burning in re-encodes the picture at a high quality setting, and copies the sound. Adding a track copies both picture and sound, so it’s quick and lossless.

Are my videos and subtitles uploaded anywhere?

No. Your videos and subtitles are opened and processed on your device, and the results are saved straight back to it. Nothing is uploaded. How to check.

Is it free? Do I need an account?

It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
