Summary
- To add subtitles to TikTok videos that every viewer sees, burn them into the picture: TikTok, like other autoplay feeds, ignores separate subtitle files.
- Generate timed cues, keep lines short, check them, then style and burn them in with a rendered preview, so captions stay clear of on-screen controls and faces.
- VideoText goes from video to SRT to a styled MP4 in the browser, from your computer. Free exports are 720p with a small watermark; Pro exports at original resolution with no watermark.
- Generate subtitles for your TikTok clip in Video to Subtitles, then burn them in with Burn Subtitles.
Subtitles on a TikTok video do two jobs at once. They make the clip watchable with the sound off, and they're part of the look. Get the first wrong and people scroll past; get the second wrong and the captions cover the speaker's face or sit under the app's buttons.
This guide shows how to add subtitles to TikTok videos and other short vertical clips in 2027 from a computer, for creators, social teams and agencies producing clips at volume. You finish with one MP4 that has the captions in the picture, ready to upload to TikTok the way you upload any video.
Caption a clip now: upload it to Video to Subtitles. Free covers one subtitle job a day, no card needed.

Step 1: Generate subtitles from your video file
Upload the video file to Video to Subtitles. Choose the spoken language from its list or leave it on auto-detect, and download SRT or VTT. The free plan handles files up to 30 minutes, one subtitle job a day.
Correct the words before anything else: names, product names and slang are where captions most often go wrong, and burned-in mistakes can't be edited later. For edits after generating, see editing subtitles after you generate them.
Step 2: Keep lines short and readable
Vertical video leaves little width, so short lines matter more than usual. Run the file through Fix Subtitles, which re-wraps text onto at most two lines and gives cues faster than 20 characters per second more time where the next cue allows it. Its default line limit is 42 characters, which suits widescreen. A vertical frame fits fewer characters, so if a line looks crowded, shorten or split it, then check the rendered frame in Step 3. The free SRT validator shows any remaining problem by cue number.
Step 3: Style it and approve a rendered frame
Subtitle Style Studio is built for this step:
- Presets: 12 tested presets in Creator, Professional and Premium collections. Four are free.
- Rendered preview: render a real export frame and approve it. The approved frame is what the MP4 shows.
- Safe areas and wrapping (Pro): margins, line limits, background, outline, shadow and restrained motion.
- Fonts and colours (Pro): eight approved font families, text and highlight colours.
- Saved styles (Pro): up to 20 personal styles, so every clip in a series matches.
Styling keeps your text and cue timing. Highlighting follows cue timing; no word timing is invented. When you approve the frame, check that captions sit clear of the speaker's face and of the areas where the app overlays its own buttons and text.
For readability fixes, see making burned-in captions easier to read.
Pick a look for your series: open Subtitle Style Studio. Four presets are free; render a frame before you export.
Step 4: Burn the captions in and export for upload
Export the styled MP4 from Style Studio, or use Burn Subtitles for quick standard captions (text size, position and background). Either way you get one MP4 with captions in the picture, which you then upload to TikTok as usual. Burn Subtitles is built for feeds like TikTok that ignore subtitle files, and it runs in the browser, so no desktop editing app is needed.

If the file is too big to send or upload, Compress Video can make it smaller; the Mobile profile goes up to 480p for the smallest files. Free accounts can compress one video a day, up to 30 minutes.
Step 5: Versions and languages
- Several languages: translate the SRT in Translate Subtitles (104 target languages, every cue's timing kept), check line length again because translations run longer, and burn each language into its own MP4.
- A series: reuse a saved style so every clip looks the same.
- Keep the SRT: if a platform also accepts subtitle files, upload the SRT alongside the burned-in video for viewers who prefer it.
A per-clip checklist
FAQ
Should subtitles on TikTok videos be burned in?
Usually, yes. TikTok and other autoplay feeds ignore separate subtitle files and often play muted, so captions in the picture are the reliable option.
How long should caption lines be for vertical video?
Shorter than for widescreen. VideoText's default limit is 42 characters per line, which suits widescreen; a vertical frame fits fewer, so shorten or split crowded lines and check the rendered frame before you burn in.
Can I keep the same caption style across a series?
Yes. Style Studio on Pro saves up to 20 personal styles.
Can I add subtitles to TikTok videos for free?
Yes. Free handles one clip a day, up to 30 minutes, with four presets; burned-in exports are 720p with a small watermark.
How do I add subtitles to a TikTok video from my computer?
Upload the video file to Video to Subtitles in your browser, correct the words, check line length in Fix Subtitles, then burn the captions in with Burn Subtitles and upload the MP4. No desktop app is needed.
