Hangul done right

Korean captions that respect the script

Most caption tools treat Korean like English with different letters. It is not. Hangul packs each syllable into a block, so lines fill up fast, spacing rules trip up transcription, and karaoke timing has to follow spoken words. This Korean subtitle generator handles all of that inside a full editor. It comes with an 86-language subtitle translator built in.

Built for Korean

What makes this Korean caption tool different

Everything below ships in the free browser editor, no download and no plugin.

  • Auto-detected Korean speech recognition

    Upload and click Subtitles. The AI hears that the audio is Korean on its own, so there is no source-language menu to get wrong. If your video mixes languages, a From-language override appears after transcription so you can force Korean and re-run.

  • Native Hangul rendering, no broken blocks

    Captions render Hangul syllable blocks natively, so 뷁 displays as cleanly as 가. Because one block equals a whole syllable, Korean lines carry more meaning per character than Latin text. Broadcast and Netflix conventions keep Korean lines to roughly 16 characters, and the cue editor makes splitting long lines a two-click job.

  • 176 caption presets, karaoke included

    Pick from 176 named presets in the caption generator, including word-by-word karaoke styles with active-word fill that follow each spoken Korean word. Recolor or emphasize individual words, so a brand name or a punchline pops mid-sentence.

  • Translate between Korean and 85 other languages

    Korean is a verified entry in the 86-language translation catalog. Turn Korean captions into English subtitles, or translate an English video's captions into Korean for viewers in Seoul. Translation is a Pro feature and rewrites the subtitle text only; your original audio stays untouched.

  • Dual Korean and English subtitles

    Show the original Korean line with its translation directly underneath using bilingual subtitles. K-content channels use this for international fans, and Korean teachers use it so students can read Hangul while checking meaning.

  • Cue-by-cue editing on a real timeline

    Every cue sits on the timeline with word-level timestamps. Fix spacing (띄어쓰기 is the usual transcription slip), correct names and English loanwords, retime a cue by dragging its edges, or split it where the phrase naturally breaks.

  • SRT or VTT in, four formats out on paid plans

    Already have a Korean SRT or VTT from a translator? Import it and style it. On a paid plan, download finished subtitles as SRT, VTT, TXT or JSON for YouTube uploads, players and archives. Free plans can burn the captions into a 720p video instead.

  • A Korean subtitle generator inside a full editor

    This is not a one-trick converter. The same project can add subtitles, trim clips, add music, animate text with 81 animations and resize for Shorts.

How it works

How to add Korean subtitles to a video

From upload to burned-in Hangul captions in four steps.

  1. Upload your video

    Drag in MP4, MOV, WebM, MKV or any of 20 accepted formats. EchoWave runs in Chrome, Edge, Firefox and Safari, and the canvas sizes itself to your first clip automatically.

  2. Generate the Korean subtitles

    Open the Subtitles panel and click auto subtitles. Speech-to-text detects the Korean, transcribes it, and lays word-timed cues on the timeline. Mixed-language audio? Use the From-language override after transcription and re-run.

  3. Proofread and style

    Scan the cues for spacing, names and loanwords, then split any line that runs past comfortable reading length. Apply one of 176 presets, or set your own font, size, outline and position, and save the look for next time.

  4. Translate, burn in, export

    Optionally translate the track into English or any of 85 other languages (a Pro feature), or stack both as dual subtitles. Export burns the captions permanently into the video, free in HD 720p with a small removable watermark badge, or up to 4K on Pro.

Who uses it

Where Korean subtitles earn their keep

  • K-content commentary channels

    Reaction and commentary creators covering K-pop and K-dramas caption their own Korean-language takes for international subscribers. Dual Korean and English tracks keep both audiences reading the same video.

  • Korean teachers and learners

    Language teachers publish clips with Hangul on top and English underneath so students connect sound, script and meaning in one pass. Word-timed karaoke presets highlight each word as it is spoken.

  • Shorts and Reels for Korean audiences

    Feeds autoplay muted, so a vertical clip without captions loses viewers in the first second. Generate Korean captions, apply a bold karaoke preset, and resize the same project to 9:16 without re-editing.

  • Mukbang and daily vlogs

    Casual formats are full of quiet asides, chewing pauses and off-mic comments that viewers miss without text. Word-level timestamps keep captions locked to relaxed, uneven speech.

  • Sermons, lectures and community groups

    Korean-language churches and community organizations serve second-generation audiences who follow English better than Korean. Transcribe the talk, add an English translation track, and publish one video both generations can follow.

  • Brands entering the Korean market

    Take an existing English product video, auto-caption it, then translate the subtitle track into Korean instead of reshooting. Upload a brand font through the brand kit so titles match your Korean landing pages.

Korean Subtitle Generator FAQ

How does a Korean subtitle generator work?

AI speech-to-text listens to the audio, recognizes the Korean, and converts it into timed text cues with a timestamp on every word. EchoWave places those cues on an editable timeline, where you correct wording, adjust timing and apply a visual style. On export the subtitles are burned into the video, or on a paid plan downloaded separately as SRT, VTT, TXT or JSON.

Do I have to select Korean before transcribing?

No. The speech recognition detects the spoken language on its own, so there is no upfront language menu. If a video mixes Korean with heavy English and the detection lands wrong, a From-language override lets you set Korean manually after transcription and run it again.

How accurate are AI-generated Korean subtitles?

Clear, well-recorded Korean speech transcribes very reliably. The usual fixes are 띄어쓰기 spacing, proper nouns, and English loanwords, which Korean speech uses constantly. Since every cue is editable in place with word-level timing already set, a proofread pass on a ten-minute video usually takes a few minutes rather than a retype.

Can I translate the Korean subtitles into English?

Yes. Korean is one of 86 languages in the subtitle translation catalog, so you can translate Korean captions into English or the reverse, plus 84 more languages. Translation is a Pro feature and changes the subtitle text only. One nuance worth a review pass: Korean honorific levels like 존댓말 flatten out in English, so check tone-sensitive lines.

Will Hangul display correctly in the exported video?

Yes. Captions render native Hangul syllable blocks in the editor, and what you see on the canvas is what gets burned in, with no tofu boxes or question marks.

Can I download the Korean subtitles as an SRT file?

Yes, on a paid plan you can download the subtitle track as SRT, VTT, TXT or JSON, which covers YouTube uploads, video players and archival copies. Free plans can burn the captions into a 720p video instead. You can also import an existing Korean SRT or VTT file and restyle it.

Is EchoWave's Korean subtitle generator free?

Yes. The free plan covers upload, auto transcription, cue editing, all 176 caption presets and export, with videos going out in HD 720p MP4 carrying a small removable EchoWave badge and a short end card. Paid plans remove both and add 1080p on Creator, then 1440p, 4K, MOV and GIF on Pro.

Can I show Korean and English subtitles at the same time?

Yes, bilingual subtitles display the original Korean cue and its translation together on screen. It is a popular setup for K-content channels with international fans and for Korean language teaching, where viewers want the Hangul and the meaning side by side.

Can EchoWave dub my video into Korean?

No. Translation here rewrites the subtitle text, and the original voice track stays exactly as recorded. EchoWave's text-to-speech library has 63 voices for adding narration, but it does not currently include Korean voices, so plan on subtitles rather than a re-voiced Korean track.
