How to Add Captions to Videos (Free, Any App)

The short answer

How to Add Captions to Videos

To add captions to videos, open your clip in a free editor like CapCut. Tap Text, then Auto Captions, and let the app turn your speech into text. Read every line and fix the mistakes. Pick a style that is easy to read, then export. Instagram, TikTok and YouTube can also add captions for you when you post.

• In CapCut, tap Text, then Auto Captions. In Canva, go to Text, then Captions.
• Auto captions make mistakes. Read every line before you post.
• Instagram, TikTok and YouTube each have built-in captions if you post in one place.

   Step 1

   Pick where to add your captions

   You have two choices. Add captions in an editing app, so they become part of the video and go wherever it goes. Or let the app you post on add them when you upload.

   Posting the same clip in a few places? Use an editor like CapCut or Edits. Posting in one app only? Its built-in captions are the quickest way.

   Step 2

   Record clear sound first

   Caption tools listen to your voice. Background noise, music over speech and people talking at once all cause mistakes. Speak clearly, stay close to the mic, and add your music after the captions are made.

   Make auto captions in CapCut

   Here is how to add captions in CapCut. On your phone, open your project and tap Text, then Auto Captions. Choose your audio source and wait. On the website, click Text, then Auto Captions, pick the language and click Generate.

   In the desktop app, the path is the same, but the last button says Recognize. A few moments later, the captions show up as blocks on the timeline under your video.

   Fix the mistakes

   Never trust the first draft. Auto captions trip over accents, fast speech and noisy clips. In CapCut, tap a caption clip on the timeline, then tap Edit captions. Tap any line and type the right words.

   Is one caption too long to read in time? Move the playhead to a natural pause and split the caption with the scissors icon. Then play the whole video with the sound on and check the timing.

   Before you post, check:
   - Names and brand words are spelled right
   - Numbers and prices are correct
   - No caption runs past two lines
   - Words appear as they are spoken
   - Nothing sits behind the app's buttons

   Step 5

   Style them so they're easy to read

   Good captions are boring in the best way. Pick a clean, bold font. Use light text with a dark outline or a dark box behind it, so the words show up on any background.

   Keep each caption to one or two short lines. Place them low on the screen, but clear of the buttons and text that apps lay over the bottom of your video.

   Step 6

   Export and check on your phone

   Export the video, then watch it on your phone before you post. Captions that looked fine on a big screen can be tiny in your hand. If you have to squint, make them bigger and export again.

   Add captions in Canva

   Making your video in Canva? Open the design and go to Text. Under Dynamic text, select Captions. Choose a caption style pack, then select Generate captions. Canva adds the captions to your video timeline.

   Canva has more than 20 style packs to choose from. To fix a word or the timing, edit the caption on the timeline. The captions download with your video. You need to be logged in to a Canva account.

   Add captions to Instagram Reels

   For styled captions, use Edits, Instagram's free editor. Open a project and tap Captions. Choose the language you speak in the video and a style, then tap Generate Captions. To fix a word, select the captions layer and tap Edit.

   Want the quick way? When you share a reel in the Instagram app, tap More options on the last screen and turn on Enable closed captions. Instagram then writes out the speech at the bottom of the reel.

   Add captions to TikTok videos

   Record or upload your video in TikTok and go to the preview screen. Tap Captions on the side panel. TikTok turns your speech into text. Check each line, fix what's wrong, then tap Save.

   TikTok also makes auto-generated captions for videos you upload. To set their language, tap More options on the post screen, then Select video language. Do that before you tap Post.

    Add captions to YouTube videos

    YouTube makes automatic captions in the languages it supports, and adds them to your video when they're ready. To fix them, sign in to YouTube Studio and select Subtitles in the left menu. Click the video, then edit the lines that are wrong.

    To write your own, click Add language and pick your language. Then click Add under Subtitles. You can upload a caption file, paste in a transcript with Auto-sync, or type the words as you watch.

Mistakes to skip

• Posting auto captions without reading them

  Read every line once. Speech tools mishear accents, fast talkers and noisy clips.

• Making captions with the music turned up

  Mute or lower the music first. Make the captions, then bring the music back.

• Picking a fancy font nobody can read

  Use a bold, plain font with a dark outline or box. Test it on a phone held at arm's length.

• Hiding captions under the app's buttons

  Keep your text clear of the very bottom and the right edge, where apps place buttons and descriptions.

Bottom line

Open your next video in CapCut and tap Text, then Auto Captions. Spend two minutes fixing the mistakes and export. Posting in one app only? Turn on its built-in captions and you're done.
