How to Add Subtitles to YouTube Videos, SRT Upload vs Burning In

TL;DR: If your goal is search visibility and multiple languages, upload an SRT file. If your goal is beautifully designed captions, burn them into the video. The best move is doing both: upload a video with designed captions burned in, and attach an SRT alongside it.

There are two main ways to add subtitles on YouTube. They serve completely different purposes, and once you know the difference, choosing is easy.

Method 1: upload an SRT file (soft subtitles)

An SRT is a simple subtitle file that says "this sentence, from this second to that second." Attach it in YouTube Studio and viewers can toggle it on and off with the captions button.

Pros

• Search visibility: YouTube and Google read the subtitle text, so your video gets more chances to match search queries
• Multiple languages: you can attach English, Spanish, Japanese, and more SRTs to the same video
• Accessibility: covers deaf and hard-of-hearing viewers, plus anyone watching with the sound off
• Doesn't cover the picture

Cons

• No design control: viewers see only the default style set by their player settings
• Practically invisible in Shorts (viewers rarely turn captions on)

How to upload: YouTube Studio, then Subtitles, then pick a language, then upload the file. To create the SRT, use the "export SRT" option in a subtitle tool. bakecut can save its transcription results as SRT too.

Method 2: burn into the video (hard subtitles)

This bakes the captions directly into the video pixels at export. The styled captions you see all over YouTube, with word emphasis and emoji effects, are all done this way.

Pros

• Full design freedom: fonts, colors, background boxes, per-word emphasis, animation, all possible
• Looks identical on every platform (including Shorts, Reels, and TikTok)
• Viewers can't turn them off, so your creative intent comes through 100%

Cons

• Viewers can't turn them off (a pro and a con)
• Search engines can't read the subtitle text
• Fixing a typo means re-exporting the video

The technical differences are covered in detail in hard vs soft subtitles.

The real answer: do both

If you publish videos regularly, this combination is the strongest:

1. Transcribe in a subtitle tool, then fix any typos
2. Burn the designed captions into the video and upload it (viewing experience)
3. Export the same transcription as an SRT and upload it to YouTube too (search visibility plus accessibility)

You transcribe once and export twice, so the extra work takes under a minute. For getting a clean transcription in the first place, see how to improve auto-caption accuracy.

Can't I just rely on YouTube's auto-captions?

YouTube's free auto-generated captions are also soft subtitles. They're far better than nothing, but typos go out as-is and sentence breaks are awkward. For the sake of your channel's first impression, we recommend proofreading a transcription once and uploading it as an SRT.

Wrap-up: transcribe once, export twice

With bakecut (available on Mac and Windows), this gold-standard combo happens in one flow. Run AI transcription, burn designed captions into the video, then save the same result as an SRT and upload both to YouTube. You get the viewing experience and the search visibility at the same time.

FAQ

How do I create an SRT file for free?

Run auto-transcription in a subtitle tool (bakecut, Vrew, and others) and export as SRT. You can also type one by hand in a text editor, but matching the timing manually is not recommended.

Can I upload an SRT to Shorts?

Technically it attaches, but Shorts viewers almost never press the captions button. For Shorts, captions burned into the frame are effectively mandatory. For styling rules, see the Shorts captions guide.

Do hard subtitles hurt my YouTube search ranking?

Hard subtitles themselves don't hurt you; they just provide no text for search to use. That's why we recommend uploading an SRT alongside hard-subtitled videos too.

Can I fix subtitles on a video I already uploaded?

SRT (soft) subtitles can be replaced anytime. Burned-in captions require re-uploading the video itself, so always check for typos before you publish.
