Add captions to a Loom video
Loom says users can’t upload external subtitle files, so to add captions to a Loom video you correct the captions Loom makes from its transcript, or, for a copy of the recording on your computer, make an SRT with the free generator below and share it with the video elsewhere.

How it works
How do you caption a Loom recording you also have as a file?
Drop the file on the generator. It transcribes the speech and sets it out as numbered captions, each timed to the moment it’s said. Read them in the preview, then save the SRT, or the VTT that Vimeo prefers, for the place the video will be watched.
- 1
Use your own copy
The recording as a video file on your computer. MP4, MOV and WebM all work.
- 2
Read the captions
Up to 30 minutes of each file are captioned, and every caption shows its start and end.
- 3
Save SRT or VTT
The file takes your video’s name, ready to upload beside it.
Can you upload an SRT file to Loom?
No. Loom’s help says it plainly: users can’t upload external subtitle files to Loom. Captions on a Loom come from Loom’s own transcript, which you can correct. An SRT of your own is for copies of the recording you share somewhere that takes caption files.
Loom’s feature request for SRT uploads, LOOM-217, has the status Gathering Interest.
Loom’s captions
Made from the video’s transcript. Viewers turn them on with CC; you fix them by correcting the transcript.
Your SRT, elsewhere
Made here from a copy of the recording, then uploaded with that copy to YouTube, Vimeo or Google Drive.
Subtitles in the picture
Drawn into a copy of the video, so the words show in any player the file is opened in.
How do you fix Loom’s captions?
Fix the transcript and the captions follow, as Loom’s help describes. Open Transcript, choose Edit, and use Delete, Correct or Correct all on the wrong words. Select Done when you’ve finished, and viewers who turn on CC read the corrected text.
- 1
Open the transcript
Go to Transcript on the video and select Edit.
- 2
Change the words
Pick Delete, Correct or Correct all for each wrong word or phrase.
- 3
Select Done
The closed captions now show the corrected text.
Who can save Loom’s captions as an SRT?
Creators and admins on Business and Business + AI, and members and admins on Enterprise. They select the “…” above the video, then Download captions, and get an SRT of Loom’s captions. That file works anywhere an SRT does, such as YouTube or a video editor.
Loom’s help lists Download captions for those roles only. Anyone else can make the SRT here from their own copy of the recording.
How do you share a Loom recording with your own captions?
To add captions to a Loom video you show outside Loom, start from a copy of the recording on your computer. Make the SRT here, then upload the video with it to YouTube, Vimeo or Google Drive, which all accept caption files.
For a copy that travels as a file, burn them into the video and the words come along in every player.

What if your recordings have more than one speaker?
NoteOwl on your Mac labels them. Bring a recording into NoteOwl and it’s transcribed by on-device AI models, unlimited, with each voice told apart, and saved as an SRT whose captions carry the speaker’s name. It records your calls on the Mac too, without a bot in the meeting.
FAQ
Questions about Loom captions
Is Loom adding SRT uploads?
Its help says users can’t upload external subtitle files to Loom, and the public request for it, LOOM-217, is marked Gathering Interest.
How do viewers turn on captions in a Loom?
With CC on the video. The captions show the words of the video’s transcript, including any corrections the creator has made.
Why can’t I see Download captions on my Loom?
Loom offers it to creators and admins on Business and Business + AI, and to members and admins on Enterprise. Anyone else can make the SRT on this page from a copy of the recording on their computer.
Should I use Loom’s captions or an SRT from here?
Inside Loom, use Loom’s: they’re already there, viewers switch them with CC, and you correct them through the transcript. Make an SRT here for a copy of the recording you post on another site, or to put the words into the picture.
Does the generator add speaker names?
No. Every caption holds just the spoken words. NoteOwl on a Mac writes SRT files that name each speaker, from recordings you import.
Is my recording uploaded?
No. Your browser opens the file where it is and keeps the picture there. The audio is cut into short pieces, each transcribed by a cloud AI transcription service and then thrown away; the captions are built in the page, and NoteOwl saves nothing.
How long can the recording be?
Each file is captioned up to 30 minutes, and you can caption 3 files a day with no account.
