How to Add Subtitles to Videos for TikTok (and Reels, Shorts)

By NUR Technologies · October 28, 2026 · 4 min read

On TikTok and Reels people scroll fast and often muted. Readable subtitles keep them watching. You can use the app’s built-in captions, or prepare them yourself before you upload, with full control of the style.

Built-in captions vs your own

TikTok’s own editor can generate captions you can then edit. That is quick, but you work inside the app and the look is limited. If you want a consistent style on every video, or you post the same clip on several platforms, prepare burned-in captions on your computer first.

3. Tune itAdjust font, colors, outline, box, animation, size and position.
4. Export an MP4Save the MP4 with the captions burned in and upload it.

What makes subtitles work on a phone

• Short lines, a few words at a time. Long blocks get skipped.
• High contrast: use an outline or a box behind the text so it reads on any background.
• Keep them clear of the app’s buttons: leave room at the bottom and the right edge.
• Proofread: names, brands and numbers are where automatic transcription slips.
