Captions Cut

How to add captions to a LinkedIn video

By the maker of Captions Cut. Facts checked on from the pages listed under Sources.

The short answer

LinkedIn adds automatic captions in 10 languages when you turn on Add auto captions at upload, and takes SRT files on desktop. Burned-in captions made with Captions Cut are read by everyone, in any language, sound on or off; a vertical 9:16 clip works, as do square and landscape ones.

Caption files. LinkedIn takes SubRip (.srt) files, from the desktop site; video ads also take captions as SRT only.

Where captions are safe

LinkedIn publishes no safe zone for organic video. Captions Cut keeps captions inside the area the vertical apps leave clear: below the top bar and above the caption, buttons and username at the bottom. Drag them anywhere if your shot needs it.

Burn captions into a LinkedIn video with Captions Cut

  1. Open captionscut.com/edit in a browser, or the Captions Cut iPhone app, and add the clip.
  2. Choose the spoken language or leave it on Auto detect (53 languages), check the cost (1 credit per second of audio) and create the captions.
  3. Read the transcript and tap any word to fix it.
  4. Pick one of 48 styles and place the captions clear of the app’s buttons.
  5. Export in 1080p or 4K and post it to LinkedIn.

The video stays on your device: only the audio is sent for transcription, and it is deleted right after.

How we checked

Every LinkedIn fact on this page comes from the platform’s own help, ads or developer pages, read on 22 October 2026. Where a page says nothing (a language list, a safe zone), this page says so rather than guess. Ads-guide numbers are for ads; organic posts have the same buttons in the same places.
