How to Make Subtitles for TikTok (Step-by-Step Guide)
Videos with subtitles consistently outperform videos without them on TikTok. Here is the fastest way to create accurate TikTok subtitles using AI.
Why subtitles matter on TikTok
More than 85% of social media video is watched without sound. On TikTok, where videos autoplay in a feed, most viewers are in environments where they cannot or choose not to use audio — commuting, in bed, in class, at work. Subtitles are not a nice-to-have for TikTok creators; they are essential for maximising reach.
Beyond silent viewing, subtitles have several additional benefits for TikTok performance:
- Higher completion rates. Viewers who can follow along with text watch more of the video. TikTok's algorithm heavily weights watch time and completion rate in its ranking signals.
- Accessibility. Deaf and hard-of-hearing viewers can follow your content. This represents a significant audience segment that creators without subtitles are leaving behind.
- Non-native speakers. Text helps viewers whose first language is not English follow along even when spoken audio is fast or accented.
- Reinforcement. Seeing words on screen while hearing them reinforces understanding and memorability — important for educational and tutorial content.
Method 1: Use TikTok's built-in auto-captions
TikTok has a built-in auto-caption feature that you can enable when uploading a video:
- Record or upload your video in the TikTok app
- On the edit screen, tap the “Captions” button (speech bubble icon)
- TikTok generates captions automatically — review and correct any errors
- Publish the video with captions enabled
This is the quickest method but has limitations: TikTok's auto-captions are frequently inaccurate for fast speech, accents, or industry-specific vocabulary. They also offer limited formatting control — you cannot change font, size, colour, or animation style significantly.
Method 2: Transcribe first, then add manually (recommended)
For better accuracy and more creative control, use an AI transcript as your source material:
- Transcribe the video using TranscribeVideo.ai — paste the TikTok URL and get the full text in under 30 seconds.
- Review and correct the transcript text, fixing any errors or awkward phrasing.
- Import into your editing tool. CapCut, Adobe Premiere, DaVinci Resolve, and most other video editors allow you to add text as subtitles or captions. Paste the corrected text as the source for your captions.
- Format the subtitles. Keep each caption to 1–6 words. Use bold, high-contrast text. Position at the bottom of the frame but above any TikTok UI elements (avoid the bottom 20% of the screen where the like/comment icons appear).
- Export and upload the video to TikTok with baked-in subtitles.
Best practices for TikTok subtitles
- Keep lines short. 1–3 words per subtitle line is ideal for animated captions. 4–6 words for standard line-by-line captions. Long lines are hard to read on mobile.
- Use high-contrast colours. White text on a dark background or black text on a white background. Avoid colours that blend into your video footage.
- Add a text background or outline. A semi-transparent box or outline behind subtitle text ensures readability over any background colour in the video.
- Match the timing to your speech. Subtitles should appear as you say the words, not before or long after.
- Avoid covering the subject's face. Position captions at the bottom of the frame, not centred over the speaker.
- Proofread before publishing. Subtitle errors are highly visible and can undermine audience trust, particularly for professional or educational content.
FAQ
Does TikTok automatically add subtitles?
TikTok offers an auto-captions feature in the app, but it often contains errors and limited formatting options. For accurate, well-formatted subtitles, generating a transcript with AI first gives you better control over the text before adding it to your video.
Why do TikTok videos with subtitles get more views?
Over 85% of social media videos are watched without sound in public settings. Subtitles allow viewers to follow along silently, increasing the likelihood they watch the full video. TikTok's algorithm rewards completion rate, so more viewers finishing the video means greater reach.
What is the best font and style for TikTok subtitles?
Bold, high-contrast text — white with a dark outline or a coloured background — works best on TikTok. Keep subtitle lines to 1–2 words maximum when animated word-by-word, or 3–6 words per line for standard captions. Avoid small fonts that disappear at mobile screen sizes.
Can I use a transcript to add subtitles to TikTok in CapCut?
Yes. Generate the transcript in TranscribeVideo.ai, copy it, and use it as your subtitle source in CapCut. CapCut's auto-caption feature can also generate captions directly, but starting from a corrected transcript ensures higher accuracy.
