How to Add Captions to a LinkedIn Video (2026)

Adding captions to a LinkedIn video means the feed can be watched with the sound off and still say what you said. LinkedIn autoplays native video muted. If the words are only in the audio, most people never hear them.

You need a video you posted, or the file before you post it. You cannot hang an SRT on someone else's upload. Ads, Live, and a document carousel are different surfaces. This guide is native video.

The Facebook version of the same job, including why the menu moves, is how to add captions to a Facebook video.

Direct answer

1. Caption the exact file you will upload, not a longer cut.
2. Make an SRT and read it once.
3. Post the video on LinkedIn, or open the video you already manage.
4. Use LinkedIn's caption upload when that control is on the post.
5. If the control is missing, burn the words in only for that feed, and still keep the SRT.
6. Play it muted on a phone before you call it done.

Start from the file LinkedIn will play

A trim, a new intro, or a LinkedIn-compressed copy with a different length will shove every line early or late. Build the SRT from the export you are about to upload. If the video is already live, use that same master if you still have it.

LinkedIn's own automatic captions are a draft. Names, product terms, and numbers are the usual misses. Treat them the way you treat YouTube auto captions: useful until a proper noun shows up.

Make the SRT before you look for the button

1. Upload the video or its audio on File Transcribe.
2. Fix names and the offer in the editor. A LinkedIn viewer will screenshot a wrong title.
3. Keep lines short enough for a phone. The number is in how many characters per line in subtitles.
4. Export SRT on Pro.

Guest try is on the homepage. Free is about 50 minutes a month. Pro is about $19 a month for about 2,000 minutes, including SRT and VTT. Plus is about $49 a month. Confirm on pricing. File Transcribe does not post to LinkedIn.

Run the caption file checklist before the upload: no empty cues, two lines at most, language obvious, filename tied to this video.

Upload the SRT when LinkedIn shows the control

LinkedIn has put captions on the post composer, on the video after publish, and inside Page admin tools. The label changes. Look for an upload that accepts a caption file, usually SRT, and a language.

Attach the SRT. Set the language to the language spoken in the audio. Save. Then watch with sound off.

If you manage a Page, check the Page's video tools when the personal post menu has nothing. Same rule as Facebook: follow the file upload, not a blog screenshot from last year.

When there is no caption upload

Some formats still have no sidecar. A short clip in a placement that only accepts the MP4 is the usual case.

Then you have two honest options:

• Burn the words into the picture for that LinkedIn upload, and keep the SRT for everywhere else.
• Put the video on a page that accepts a track, and link it. YouTube's path is how to add captions to YouTube videos.

Burned-in text cannot be corrected in LinkedIn later. The SRT can. CapCut captions vs an SRT file is the decision if the edit already happened in CapCut.

Do not assume a burned-in MP4 satisfies a client who asked for closed captions. Closed means a track people can turn on. The distinction is in closed captions vs subtitles.

Check it the way the feed shows it

1. Sound off.
2. Phone, not only desktop.
3. First three seconds. If the hook is late, the caption is late.
4. The name and the number in the middle of the video.
5. The last line. It should end when the thought ends, not halfway through a word.

If you are also posting the same file to Facebook, reuse the SRT only when the cut matches. A square crop that chopped the last second needs its own timing.

FAQ

How do I add captions to a LinkedIn video?

Export an SRT timed to that exact file, open the LinkedIn video you manage, and upload the SRT where LinkedIn asks for captions. Set the spoken language. Watch it muted on a phone.

Does LinkedIn auto-caption native video?

Often yes, as a generated track. Replace it or edit it when names and offers matter and LinkedIn still lets you add your own file.

Can I caption a LinkedIn video with an SRT after it is live?

When the post or Page still shows a caption upload, yes. If that control is gone, you are looking at a new upload or burned-in text. The menu is not stable enough to promise one path.

What if I only have the MP4?

Upload it on File Transcribe, edit the transcript, export SRT on Pro. That file is what you attach. The subtitle generator is the same upload if you want the tool page instead of the homepage.

Should the captions be burned in for LinkedIn?

Burn them in when the placement will not take an SRT and the video must make sense muted. Keep the SRT anyway. The next channel may want the file.

Upload the master on the homepage before you post. Same SRT can go to YouTube if that upload is the same cut.
