Add Subtitles to a TikTok Video
To add subtitles to a TikTok video, upload your clip, select the TikTok caption style, and the AI transcribes your speech into bold captions that highlight each word as it is spoken — the same punchy look you see on viral clips.
That word-by-word rhythm is not just decoration: it pulls the eye back to the screen and keeps people watching past the first seconds. Recreating it manually means animating every single word, which is exactly the tedious part this tool automates.
How it works
- 1
Upload your clip
Add your TikTok video — up to 500 MB — and set the spoken language to English, French, Spanish or German, or keep auto-detect on if you are not sure.
- 2
Select the TikTok style
Choose the TikTok preset for bold text with word-by-word highlighting. Place the captions at the bottom, middle, top, or dial in a custom height so they clear TikTok UI overlays.

Download and post
Grab the finished video with subtitles baked into the image and upload it straight to TikTok. No extra steps in the TikTok editor, no font or timing tweaks needed.
Why use Video-Matic
Word-by-word highlight
The TikTok preset lights up each word in sync with the voice — the high-retention caption style creators use, generated automatically.
Custom caption height
Position subtitles anywhere on the frame so they never collide with the TikTok caption bar, buttons or your own on-screen text.
Clean output, no branding
The downloaded video carries no added watermark, so your post looks like it came straight out of a pro editing app.
Runs on your phone
Everything works in a mobile browser — record, upload, caption and post without ever moving files to a computer.
Frequently asked questions
How do I get the TikTok caption style with the highlighted words?›
Pick the TikTok style when setting up the job. It renders bold, high-contrast text and highlights each word at the exact moment it is spoken, matching the caption look popular on TikTok. Classic and Dream styles are also available if you want something calmer.
Does this cost anything?›
You get 3 free credits when you create an account, and subtitling a video costs 3 credits, so the first TikTok you caption is free. If you caption regularly, one-time credit packs are available — no recurring subscription required.
Will the subtitles still show if TikTok compresses my video?›
Yes. The subtitles are burned into the video frames themselves, so they survive TikTok compression and display identically on every phone. They are part of the picture, not a toggleable caption track viewers can turn off.
My TikTok is in French — will the AI transcribe it correctly?›
Yes. Set the language to French before processing, or use auto-detect. The speech recognition handles English, French, Spanish and German, so multilingual creators can caption clips in any of those four languages with the same TikTok style.
