How it works
How do you make captions for a LinkedIn video?
Before posting, drop the finished clip on the generator. Its speech is transcribed piece by piece and turned into numbered captions timed to the words. Look them over in the preview, then save the SRT to the same folder as the clip.

Can you add a caption file from the LinkedIn mobile app?
No. LinkedIn’s help describes caption files only in the desktop experience. For the app, it covers Add auto captions and reviewing those captions before adding them, with no option for a file of your own. To use your SRT, post the video from a computer.
Which languages do LinkedIn’s auto captions support?
Ten, according to LinkedIn’s help: English, Spanish, Portuguese, French, German, Italian, Indonesian, Turkish, Arabic and Dutch. For a video in any other language, or when names and terms must be spelled your way, attach your own SRT instead.
The generator works out which language is spoken and writes the captions in it, in its own script; it doesn’t translate. For captions in a different language from the speech, run the SRT through the subtitle translator before you attach it.
Can a LinkedIn Page post a video with captions?
Yes. LinkedIn’s help says closed captions can be added to videos posted either by personal accounts or by LinkedIn Pages, from the desktop experience, so a company clip can carry the same SRT as one on your own profile.
Viewers decide whether they see them: LinkedIn tells them to tap Show closed captions or Hide closed captions. If the clip is vertical, tick Short lines for a vertical video under the generator’s download buttons, so each line fits the narrow frame.
How do you label speakers in a LinkedIn panel clip?
Let NoteOwl make the SRT. It transcribes recordings you import on your Mac with on-device AI models, works out who said what and saves SRT captions that begin with each speaker’s name, unlimited. The clip then shows who is talking without extra text on screen.
Hosting the webinar yourself? NoteOwl also records meetings on your Mac with no bot joining the call, and writes the transcript and notes when it ends.
FAQ
Questions about LinkedIn video captions
What caption file does LinkedIn accept?
An SRT. LinkedIn’s help names SubRip (.srt) files for closed captions on video posts, and that’s the generator’s first download.
Why can’t I find a caption file option on my phone?
LinkedIn’s help describes attaching a caption file only when you post from a computer. The mobile app offers auto captions, which you can review before adding them. Post from a computer to attach your own SRT.
Should I use LinkedIn’s auto captions or my own file?
Your own file when the video is in a language LinkedIn doesn’t auto-caption, or when names, product terms and spelling have to be right. Its auto captions cover ten languages; an SRT made here follows whatever language is spoken.
How long can the clip be?
The generator captions 30 minutes of each file, 3 files a day, free and without signing up. A longer recording is captioned up to that point.
Will the captions say who is speaking?
No. The web generator writes the spoken words only. NoteOwl, the Mac app, saves SRT files that start each speaker’s captions with their name.
Where does my video go while the captions are made?
Nowhere: it stays on your computer. What travels is its sound, cut into short pieces, to a cloud AI transcription service that transcribes and discards each one. Your browser lays the words out as captions, and NoteOwl stores none of it.
