Quick answer: Facebook offers two native translation options, DLO and Automatic Translation. Neither touches text in images. For Korean, you get better results by pairing those tools with AI translation and image text editing in Coinis Revise.

Why Translate Facebook Ads to Korean?
Korean speakers engage more when ads appear in their own language. Translated ads lower cost per acquisition and build trust.
Reach native Korean speakers in their preferred language
Facebook targets based on a user's language setting, not their location alone. Korean speakers worldwide see your ad, not just audiences in South Korea.
Higher engagement and conversion when ads match user language settings
Per Meta's Ads Guide, Facebook matches the right language variation to each user's selected Facebook language. Matching that preference boosts relevance and clicks.
Cultural resonance improves performance
Translation alone isn't enough. Korean audiences respond to different tones and cultural context than English-speaking audiences. Adapting content for cultural fit, known as transcreation, drives stronger results.

Three Ways to Translate Your Facebook Ad
You have three options: Facebook's Dynamic Language Optimization, Automatic Translation, or AI-powered translation with Coinis Revise. Each fits a different need.
---
Method 1: Set Up Facebook's Dynamic Language Optimization
DLO lets one ad set deliver multiple language versions automatically. Facebook shows the right version based on each user's language setting.
Step-by-step: Create campaign with Traffic/Mobile App/Conversions objective
DLO only works with Traffic, Mobile App Install, and Conversions objectives. Start by selecting one when creating your campaign in Meta Ads Manager.
Configure placements (Newsfeed, Instagram, Audience Network only)
Per the Facebook Business Help Center, DLO supports Facebook Newsfeed (desktop and mobile), Instagram, and Audience Network. Reels, Stories, and Business Explore are not supported. Select these placements manually and deselect the rest.
Add Korean as a language variation
In the ad creation step, find the language variation option. Add Korean (한국어) alongside your default language.
Enter Korean headline, text, and link description
Type or paste your Korean copy into the headline, primary text, and link description fields. Each language gets its own copy fields.
Reporting: Track performance by language
Facebook breaks down results by language variation. Go to Breakdown > Asset Type in your reporting dashboard to compare your Korean version against other languages.
Important limits: One ad set holds only one ad when DLO is active. You can include up to 6 language variations per ad set. Bulk editing and bulk duplication are not supported.
---
Method 2: Use Facebook's Automatic Translation
Automatic Translation is simpler. No placement restrictions, no ad set restructuring needed.
Add up to 48 language options including Korean
Per Meta's Ads Guide, Facebook's Automatic Translation supports up to 48 languages, Korean included. Add Korean directly in the ad creation interface.
Click 'Translate' to auto-translate headline and body copy
Facebook generates a Korean translation instantly. The translated text appears highlighted in green so you can see exactly what changed.
Review and edit auto-translated text for accuracy
You can edit the translated text before publishing. This step matters. Facebook's translation handles simple, clear copy well but struggles with slang, idioms, and complex phrasing.
Advantages and limitations
Speed is the main advantage. Setup takes minutes. The limitation: automated translation often misses tone and cultural context. Korean audiences may find literal translations stiff or unnatural. Review with a native speaker when possible.
---
Method 3: AI-Powered Translation with Cultural Refinement (Coinis Revise)
Facebook's tools translate text fields. They never touch image text. Coinis Revise handles both.
Generate or upload your ad creative
Start with your existing ad image. Upload it directly to Coinis Revise. Or use the Image Ads workflow to generate a fresh creative from your product URL first.
Use Revise's AI Translate to create Korean version
Select AI Translate in Coinis Revise. Choose Korean as the target language. Revise applies cutting-edge AI models to produce natural Korean phrasing, not a word-for-word swap.
Edit and refine for tone and cultural resonance
AI Translate gives you a strong starting point. Then adjust tone in Revise. Korean audiences often respond better to polite, formal register in ads. Use AI Rewrite ad copy to shift tone quickly.
Handle image text translation separately
Text embedded in an ad image never auto-translates on Facebook. Revise's Edit text on image feature solves this. Select the text layer in your image, type the Korean version, and save. No separate design tool needed.

Key Considerations for Korean Ad Translation
Avoid literal translation, use transcreation principles
Transcreation adapts the message for the culture, not just the words. Korean has formal and informal speech levels. Most ads perform better in a formal, respectful tone.
Images with text: Text won't auto-translate, use Revise Edit text on image
This is the most common mistake in translated campaigns. Text baked into your image stays in English unless you edit it manually. Revise's Edit text on image fixes this fast.
Language targeting is user-based, not geo-based
Facebook targets based on users' self-selected language settings. A Korean speaker in New York sees your Korean ad. A non-Korean speaker in Seoul does not. Target language first, then layer on location if needed.
Test with native Korean speakers when possible
Run your Korean copy past a native speaker before launching. Korean is a high-context language where word choice affects trust significantly.
---
Limitations to Know
DLO only supports 6 languages per ad set
Korean plus up to 5 other languages per ad set. More languages require separate ad sets.
DLO doesn't work with Reels, Stories, or Business Explore placements
These placements are excluded from DLO. If you're running Reels or Stories, Automatic Translation or manual editing is your only native option.
Image text never auto-translates, must be edited manually
Both DLO and Automatic Translation ignore text embedded in images. This applies to all image ad formats. Use Coinis Revise to handle image text for Korean.
Automatic translation may miss cultural nuance
Facebook's AI handles basic copy accurately but still produces literal results for complex or idiomatic phrasing. Always review before publishing.

Best Practice: Combine Methods
The fastest, most effective approach layers all three methods together.
Use Facebook DLO for speed and scalability
DLO handles delivery logic automatically. Facebook decides which version to show. No need to split audiences manually or manage separate campaigns.
Use Coinis Revise to refine tone and cultural fit
AI Translate produces polished Korean copy. Edit text on image fixes your visuals. AI Rewrite ad copy lets you shift to the formal register Korean audiences expect.
Launch final version via Campaign Launcher
Once your Korean creative is ready in Coinis, use Campaign Launcher to push your campaign live to Facebook. Set your objective, audience, and budget in one workflow.

Frequently Asked Questions
Does Facebook automatically translate text in ad images to Korean?
No. Facebook's translation tools, both Dynamic Language Optimization and Automatic Translation, only translate text fields like headline and body copy. Text embedded in an image is never auto-translated. You need to edit image text manually. Coinis Revise's Edit text on image feature handles this quickly without a separate design tool.
What's the difference between DLO and Automatic Translation on Facebook?
Dynamic Language Optimization (DLO) creates multiple language variations within one ad set and automatically shows each user the version that matches their Facebook language setting. Automatic Translation translates your existing ad copy into selected languages with one click at the ad level. DLO is better for scalable multi-language campaigns. Automatic Translation is faster for one-off translations.
Can I target Korean speakers outside of South Korea on Facebook?
Yes. Facebook's language targeting is based on users' self-selected language settings, not their geographic location. Korean speakers anywhere in the world will see your Korean-language ad when you target the Korean language. Layer on location targeting if you also want to narrow by geography.
How many languages can I run at once with Facebook's Dynamic Language Optimization?
DLO supports up to 6 language variations per ad set. If you need more than 6 languages, you'll need separate ad sets. One ad set can only contain one ad when DLO is active, and bulk editing is not supported.
