LinkedIn users' attention is naturally drawn to video content (75% of business executives watch at least one work-related video per week).
But without subtitles, a part of your audience won’t get the message.
In this guide, we’ll show you how to subtitle your LinkedIn videos like a pro.
Yes, LinkedIn offers an auto-caption feature for videos uploaded via desktop and mobile. It uses speech recognition to generate subtitles automatically.
When you post a video on LinkedIn from your desktop, here’s what happens:
This step is important. LinkedIn’s auto-captions aren’t perfect. You may find small mistakes in names, terms, or punctuation — especially with fast speakers or background noise.
If you want to add subtitles to your LinkedIn video manually, you’ll need to upload a separate subtitle file.
LinkedIn supports only one format for this: the .srt file.
This is a standard format used across most platforms. But LinkedIn is very specific about how it must be formatted and used.
Here’s how to do it right:
.srt file and confirmThat’s it. Your subtitles will now display for anyone who enables captions while watching your video.
Before uploading, double-check your .srt file:
If there are any errors in formatting, LinkedIn may not accept your file — and you won’t get a warning. The captions just won’t appear.
If you’ve tried creating subtitles by hand, you know it takes time. You need to transcribe every word, get the timing just right, and format everything into a clean .srt file.
And if you want subtitles in multiple languages? Even more work.
That’s where Checksub comes in. It’s an AI-powered platform that simplifies the entire subtitling process — from transcription to export — in just a few clicks.
Here’s how to use it to create LinkedIn-ready subtitles.

It’s designed to be fast and easy — no technical skills required.
Once your subtitles are ready, go to the export screen and select .srt as your file format.
This is the exact format LinkedIn requires.
Make sure your file is:
linkedin-video-en.srt)Checksub makes sure the file is clean and formatted correctly — so you don’t have to stress about errors.
You’ve uploaded your video. You’ve attached your .srt file. But your subtitles aren’t showing — or something just looks off.
Don’t worry. Subtitles can be a bit tricky on LinkedIn, but most issues come down to small mistakes in formatting, timing, or how the file was uploaded.
Here’s how to troubleshoot and fix the most common problems.
If your subtitles don’t appear after uploading, the most likely reason is a formatting error in your .srt file.

Also, make sure you uploaded your video and .srt file using LinkedIn on desktop. Subtitles can only be added this way — not through the mobile app.
Subtitles showing up too early or too late?
This usually means the timestamps in your .srt file don’t match the actual timing of your video.
Fix it with:
Even small edits to your video (like trimming the intro) can shift the sync — so always use the final video when generating your subtitles.
Do you see strange symbols like “�” instead of accents or punctuation?
That means your .srt file was saved with the wrong text encoding.
Fix it: Open the file in a plain text editor and re-save it with UTF-8 encoding. This ensures characters like é, ñ, or ç display correctly across all devices.
If you don’t see the option to upload an .srt file, you’re probably using the wrong upload method.
Remember:
Always use a desktop browser for full subtitle support.
