How to Add Captions to YouTube Shorts: App, Studio, and Burned In

October 2, 2026

To add captions to a YouTube Short on your phone, open the YouTube app, record or import your clips, tap Done, then tap Captions in the editor. YouTube generates them from the speech, and you can change the font and colour and correct any word. On a computer, open YouTube Studio, choose Subtitles, pick the Short, and add a caption track by uploading a file, syncing a transcript or typing it in. Both are free. The choice that matters more is which kind of caption you want, because the two routes produce different things: text drawn onto the video that every viewer sees, or a caption track that only appears when a viewer turns it on.

This guide covers both kinds, the steps for each of YouTube’s tools, how to caption in your own editor, and how to make captions people can actually read on a phone. It ends with the hands-off way, for a channel that posts often enough that timing words to a voice has become a job of its own.

On-screen captions vs closed captions

Most Shorts creators who say “captions” mean the on-screen kind. People scroll Shorts with the sound off, and big words in the middle of the screen keep them watching. Closed captions do a different job: they serve deaf and hard-of-hearing viewers, and they can be corrected or translated without touching the video. A Short can have both, and plenty of good ones do.

How to add captions in the YouTube app

YouTube’s help page for its Shorts tools describes captioning as a step after recording (as of October 2026):

1. Open the YouTube app and tap Create, then Short.
2. Record your clips, or tap the gallery to import a video you made elsewhere.
3. Tap Done to open the editor.
4. Tap Captions. YouTube listens to the audio and adds the words automatically.
5. Change the font and text colour, and fix any word it heard wrong.
6. Tap Next, add a title, choose who can see it, and upload.

The same page carries a note worth reading before you count on this: “Currently, captions are only available in certain languages and mobile devices.” If you do not see a Captions button, the feature has not reached your phone or your language yet, and the computer routes below still work.

Captions made this way are part of the picture. They show for everyone and they cannot be switched off by the viewer, which is usually what you want for a Short.

How to add captions to a Short cut from a long video

If your Shorts come from your own long-form videos, YouTube Studio’s clips and Shorts tool captions them for you. Its help page says the transcript in the tool “will be used to create the auto-generated captions for your Short,” and that “where available, the system automatically adds autocaptions to the Short.” The steps (as of October 2026):

1. In YouTube Studio, open the long video and go to its Clips and Shorts tab.
2. Select the part you want as a Short.
3. Click Preview Short in the upper right.
4. Click Captions in the bottom left of the preview to change the colour, font, styling and position, or to turn the captions off.
5. Click Create Draft and finish the usual upload steps.

This is the quickest route of all when the source video already exists, because the words come from a transcript YouTube has already made.

How to add closed captions in YouTube Studio

For a Short you have already uploaded, YouTube Studio adds a closed caption track. YouTube’s help page lists the steps (as of October 2026):

1. Sign in to YouTube Studio on a computer.
2. Select Subtitles in the left menu.
3. Click the Short you want to caption.
4. Click Add language and choose the language spoken in the video.
5. Under Subtitles, click Add, then pick one of three options.

The three options do different amounts of work for you:

• Upload file. You already have a timed caption file, such as an .srt exported from an editor. The timings come with it.
• Auto-sync. You paste a plain transcript and YouTube matches it to the speech. The page notes that the transcript must be in the same language that is spoken in the video.
• Type manually. You play the Short and type as it goes. YouTube sets the timings, and the help page suggests adding sound cues such as [applause] so viewers know what is happening.

You may not need any of this. YouTube’s automatic captioning page says that “if automatic captions are available, they’ll automatically be published on the video,” and it lists English among dozens of supported languages. The same page is blunt about quality: “You should always review automatic captions and edit any parts that haven’t been properly transcribed.” To do that, open Subtitles, click the Short, and use More next to the automatic track to edit it.

If automatic captions never appear, YouTube’s troubleshooting list includes a few causes a Short can easily hit: poor sound quality, speech it does not recognise, overlapping speakers or languages, and “a long period of silence at the beginning of the video.” A music-only Short has no speech to caption at all.

How to caption a Short in your own editor

Most people who make Shorts on a computer add on-screen captions in a video editor before uploading. The details differ between apps, but the job is the same everywhere:

1. Finish the voiceover first. Captions are timed to the voice, so a late change to the audio means re-timing every line.
2. Generate a draft. Many editors have an automatic captions or speech-to-text button that writes timed lines from the audio. If yours does not, type the script and set each line’s start and end by hand.
3. Correct every word. Automatic captions mishear names, numbers and niche terms, and a wrong word on screen reads as a mistake by you.
4. Split the lines short. Two to five words per line is easy to read at Shorts speed. A full sentence on screen is too much to take in.
5. Style once and reuse it. Pick one font, one size and one highlight colour, then save it as a preset so every Short on the channel looks the same.
6. Export as a vertical 9:16 file and upload it. If your editor can also export an .srt, upload that in Studio too and you have both kinds of caption from one piece of work.

The editor route takes the most effort, and it is the only one that gives you complete control over how the words look and move.

How to make Shorts captions easy to read

Whatever tool you use, the same rules decide whether a caption helps or gets in the way:

• Stay out of the bottom and the right edge. YouTube draws the title, channel name and buttons there. Captions in the middle third of the screen are never covered.
• Make them big. The video is watched on a phone held at arm’s length. If you have to squint at your preview on a laptop, it is far too small.
• Use contrast, not decoration. White or yellow text with a dark outline or shadow reads over any background. Thin fonts and pale colours disappear over bright footage.
• Highlight the word being spoken. A colour change on the current word pulls the eye along and makes the caption feel tied to the voice.
• Keep them in time with the audio. A caption that runs half a second late feels broken even when every word is right.
• Match the words to what is said. Viewers notice when the caption and the voice disagree, and closed caption users depend on it.

If you are still writing the narration the captions will carry, how to write a script for a YouTube video covers short sentences that read well on screen as well as aloud.

When captioning by hand is enough

The manual routes are the right choice for plenty of channels:

• You post a few Shorts a week, and the YouTube app’s Captions button covers you in a minute.
• Your Shorts come from long videos you already publish, so Studio’s clips tool does the work.
• Captions are part of your style, with hand-placed words, emoji or jokes timed to the edit, and that styling is what people come for.
• The Short has no speech, so there is nothing to caption beyond a line of on-screen text.

In those cases, YouTube’s own tools are free and quick, and nothing below will beat them.

The hands-off way, for a channel that posts every day

Captioning is one of the steps that grows with volume. On a faceless channel every video needs the same run: write the script, record the voice, generate captions, fix the words, split and time the lines, style them, export, upload. Captions sit near the end, so any change to the script or the voice sends you back through them.

Nichecast is one way to take that whole run off your hands. You describe a channel once: its niche, its video style and its rules. From then on, every video it makes arrives with:

1. A script written for the channel’s niche.
2. A voiceover recorded from it.
3. Captions timed to the words of that voiceover and drawn into the video, in the look of the video style you picked.
4. A rendered 9:16 Short, uploaded to your YouTube channel as unlisted.

Because the captions are made from the same narration the video plays, they never fall out of step with the voice, and there is no line to re-time when a script changes. Nothing goes public until you publish it yourself. The Short waits in YouTube Studio, where you can watch it, change the title, and add or review closed captions with the Studio steps above.

The trade-off is control. The caption look comes with each video style, so you cannot place individual words by hand or pick any font you like. For a channel built on explainers, facts, rankings and stories, a consistent caption style is usually what the format wants. For a channel whose captions are part of the joke, keep editing them yourself.

You can try it on five free videos without a card. The free script generator needs no account if you want to see the writing first, and how to add music to YouTube Shorts covers the other finishing step that repeats on every video.

Quick answers

Does YouTube add captions to Shorts automatically? It can, in two ways. Automatic closed captions are published on Shorts when the language is supported and the speech is clear. On-screen captions are added automatically only when you use the Captions button in the app’s Shorts editor or the clips and Shorts tool in Studio.

Why is there no Captions button in my Shorts editor? YouTube’s help page says the feature is only available in certain languages and on certain mobile devices. Use YouTube Studio’s Subtitles page on a computer instead.

Can I edit captions after uploading a Short? Closed captions, yes: open Subtitles in YouTube Studio and edit the track. On-screen captions are part of the video, so changing them means editing the video and uploading it again.

Should I use both kinds? If you can, yes. On-screen captions keep sound-off viewers watching. A corrected closed caption track serves viewers who rely on captions and can be translated. For more on what helps a Short travel, see how to go viral on YouTube Shorts.
