How it works
- Drop your vertical video.
- Pick TikTok bold, which is the default on this page, and press Make captions.
- Fix the words, then Burn into video and post the MP4.
The TikTok bold look is white capitals with a thick black outline, sitting above the lower fifth of the frame where the app draws its own caption and buttons. Cues are cut short, around 22 characters per line, so the text changes every second or two.
Auto captions in the app itself work, but you cannot choose the look, and mistakes on names stay in. Here you edit the text first and your edits are what gets drawn.
If you only need the words for your post caption or description, press TXT and copy the transcript. SRT is there too for editors that import it.
Questions
Does it fit the safe area?
The text sits about a quarter up from the bottom and keeps a margin on both sides, clear of the buttons on the right.
Is there a watermark?
The free burned-in export carries a small Captionfox mark in the top corner, one per day. Paid exports have none. The SRT never has one.
