Caption generator
LinkedIn Video Caption Generator
LinkedIn plays feed videos without sound until someone taps them, so a talking-head clip without captions is a silent face. This LinkedIn video caption generator writes captions from the speech in your video, times them to the audio, and burns them into the MP4 in a plain, professional style that suits a founder update, a recruiter's job post, a coach's tip or a clip from a webinar. LinkedIn also lets you attach a caption file: as of 18 October 2026, LinkedIn Help says a video needs an associated SRT file attached before it is posted, from the desktop experience, and viewers then toggle the captions. Burned-in captions need no file and no desktop, show on every phone, and look the same in a repost. Upload an MP4 or MOV of up to 10 minutes, choose the spoken language from English and 10 Indian languages, edit, and export. 3 free minutes to start; packs from $4 (₹49 in India, €4 in the euro area).
Start with 3 free minutes. Watermark-free export comes with every paid pack.

For best results, upload a video with clear speech. You can review and edit the captions after generation.

What the captions look like
Founder update
We closed the quarter at 140 customers, up from 90.
Numbers are the first thing to check in a draft, and the first thing a scrolling reader notices. Keep the figure on one line.
Recruiter job post
Hiring two backend engineers in Berlin, hybrid, from January.
Place names, job titles and dates read better as one complete caption than as word-by-word fragments.
Coach's tip
Ask for the budget before you send the proposal.
One idea per caption. A plain white or light style with a dark backing box reads well over an office background.
Hinglish founder clip
Humne pehle 100 customers bina ads ke laaye.
For founders who speak Hinglish on LinkedIn, choose Hinglish and the line stays in Roman script as spoken.

- Plain, professional styles that suit a face, a slide or a screen recording

How it works
How it works
Step 1
Choose the framing: 1:1 or 16:9
Square fills more of the LinkedIn feed on a phone; 16:9 suits a webinar clip or a screen recording. CapsAI captions the file at the ratio you upload, so crop first in your editor if you want square. LinkedIn Pages accept ratios from 1:2.4 to 2.4:1 (LinkedIn Help, read 18 October 2026).
Step 2
Upload and pick the spoken language
Add an MP4 or MOV of up to 10 minutes. Choose English, Hinglish, Hindi or one of eight other Indian languages. The draft arrives with every caption timed to the audio.
Step 3
Edit for a professional read
Remove ums and false starts, fix company names, job titles and figures, and keep each caption to one idea. The timing stays attached to the words as you edit.
Step 4
Pick a plain style and place it low
A clean sans-serif on a dark backing box, or white text with a thin outline, sits well under a face. Keep it in the lower third, clear of any slide or screen text.
Step 5
Export an MP4 and post
Export the captioned MP4 and post it from your phone or desktop. LinkedIn's Pages spec lists MP4 and says it no longer supports MOV or QuickTime (LinkedIn Help, read 18 October 2026), so the MP4 export is the right file.
Choose your spoken language

Questions
Does LinkedIn caption videos automatically?
LinkedIn's Help article on closed captions, read 18 October 2026, describes one method: attaching an SRT file to the video before posting, from the desktop experience. It does not describe automatic captions, so we do not claim them here. Burned-in captions from CapsAI work regardless, because the text is part of the video.
Can CapsAI make the SRT file LinkedIn asks for?
No. CapsAI exports an MP4 with the captions burned in; it has no SRT or VTT download. If you have a text file of the speech, /tools/txt-to-srt-generator turns it into an SRT you can attach in LinkedIn's desktop share box. Most people posting from a phone burn the captions in instead.
Which aspect ratio should a LinkedIn video be?
Square (1:1) takes up more of the feed on a phone; 16:9 suits webinar clips and screen recordings. LinkedIn's video spec for Pages accepts any ratio between 1:2.4 and 2.4:1, up to 10 minutes and 5 GB (LinkedIn Help, read 18 October 2026). CapsAI captions at the ratio you upload, so crop before uploading if you want square.
Is the LinkedIn video caption generator free?
New accounts get 3 free minutes to start. After that, minutes come in one-time packs from $4 (₹49 in India, €4 in the euro area) for 20 minutes, 60 on Creator and 180 on Pro. Nothing renews.
Will the exported video have a watermark?
Watermark-free export comes with every paid pack. Use the free minutes to generate and edit the captions, then see the pricing page for what each pack includes.
What formats and limits apply?
Upload MP4 or MOV up to 10 minutes per video, up to 500 MB free and 10 GB with a pack. Export is an MP4 with captions burned in, 1080p on Starter and up to 4K on Creator and Pro. LinkedIn says it no longer accepts MOV or QuickTime (LinkedIn Help, read 18 October 2026), so upload the MP4 export.
Does it translate captions?
No. Captions come out in the language spoken: English or one of 10 Indian languages including Hindi, Hinglish, Tamil and Telugu. Choose the language of the clip.
How long does it take?
A few minutes for a 60 to 90 second clip, then the time you spend reading the draft. Company names, job titles and numbers are the lines to check.
Which caption style looks professional on LinkedIn?
A plain sans-serif in white or light grey on a dark backing box, or white with a thin outline, one or two lines in the lower third. Avoid word-by-word pop effects for a serious update; a karaoke highlight on a full line is as far as most LinkedIn videos should go.
Sound off in the feed
LinkedIn autoplays feed video muted, and most people scrolling at work leave it that way. A clip with captions can be read; a clip without them is a face moving its mouth. Captions also help the viewer decide in the first two seconds whether the clip is for them, which is where a founder update or a job post lives or dies.
SRT upload or burned-in captions?
LinkedIn supports closed captions through a file. As of 18 October 2026, LinkedIn Help says you must have an associated SRT file attached to the video before it can be posted, and describes the steps for the desktop experience: start a video post, open the edit settings in the preview, select the caption file, then post. Those captions can be toggled by the viewer.
Burned-in captions are the alternative, and for most people posting from a phone the practical one. There is no file to make, the captions show on every device, and they stay in the video when a colleague reposts it. CapsAI produces the burned-in version only; if you want an SRT as well and have a transcript, the TXT to SRT generator makes one.
Who uses it
Founders posting a weekly update, coaches turning a 40-minute talk into one tip, recruiters introducing a team, and marketers cutting webinar highlights for the company Page. The common thread is a clip under 10 minutes, usually under two, where the words matter more than the effects. For podcast and webinar sources, the podcast clip and webinar pages cover the cut and the speaker changes.
