How to add captions to a LinkedIn video on iPhone
Updated
To add captions to a LinkedIn video on iPhone, caption the video before you upload it: open it in CaptionAddr, which transcribes the English speech on your iPhone, check names and terms in Edit Captions, choose a clear style and export a captioned copy to Photos. Then attach that copy to your LinkedIn post. Videos up to 2 minutes are free; CaptionAddr Pro covers up to 30 minutes.
Why caption LinkedIn videos
Many people scroll their feed at work or in public with the sound off. Captions let them follow a talking-head update, a product demo or an event clip without audio, and they help viewers who are deaf or hard of hearing.
CaptionAddr burns the captions into the picture, so they show wherever the video plays, including when it’s reshared or downloaded. It doesn’t create a separate caption file, so if a platform asks for one, skip that step for a video that already has burned-in captions.
Caption a LinkedIn video on iPhone
- Choose the video. Tap Select Video in CaptionAddr and pick the clip with Apple’s Photos picker. Vertical, square and landscape videos all work.
- Let the captions generate. Captions start as soon as the video opens; keep the app open; the English speech is transcribed on your iPhone, not on a server.
- Check names and terms. In Edit Captions, correct people’s names, company names, product names and acronyms. These are the words a speech model is most likely to get wrong, and the ones a professional audience notices.
- Pick a clean style. Choose a simple font and a size that reads on a phone, and turn on the tinted background if the footage is busy.
- Place the captions. Drag the captions where they don’t cover faces, slides or on-screen text.
- Export and post. Tap Export Video to save the captioned copy to Photos, then start a post in the LinkedIn app, add the captioned video from your library and publish.
Tips for professional captions
- Proofread every word. A misheard name in a captioned video is visible to everyone, so play the whole clip once in Edit Captions.
- Trim before captioning. Cut long intros in Photos first; a shorter clip keeps attention and can stay within the free 2-minute limit.
- Record clean audio. A quiet room and a phone close to the speaker give the most accurate captions.
- Keep your original. CaptionAddr exports a new copy and leaves the original in your library.
Limits
- English only. CaptionAddr transcribes English speech and doesn’t translate.
- Length. Free covers videos up to 2 minutes; CaptionAddr Pro covers up to 30 minutes, for longer talks and webinar clips. The App Store shows the current Pro price in your currency.
- Burned-in captions only. There is no SRT, VTT or text export.
- Single-word captions. Words appear one at a time, timed automatically; full-sentence layouts and manual per-word timing aren’t available.
- No direct posting. The app doesn’t post to LinkedIn; you upload the exported video yourself.
Frequently asked questions

Caption the video in CaptionAddr before posting: generate captions on your iPhone, correct names and terms, choose a style and export. Then add the captioned copy from Photos to a LinkedIn post.
Can CaptionAddr make an SRT file for LinkedIn?
No. CaptionAddr burns captions into the video itself and doesn’t export SRT, VTT or text files.

Yes. CaptionAddr works with vertical, square and landscape videos, and you can drag the captions to any position on the preview.
Is my video uploaded for transcription?
No. Transcription runs on the device, and CaptionAddr doesn’t send your video, audio or captions to its servers for transcription. You upload only the finished copy, to LinkedIn, yourself.
