8 Best AI Tools for Localizing Ad Creative in 2026

Key takeaways

• Melius is the best overall pick. Its agent adapts copy, units, scenes and people for each market on the best model for each step, and every node stays editable.

• HeyGen is the strongest dedicated tool for dubbing a talking video ad into other languages with lip sync, in more than 175 languages and dialects.

• ElevenLabs dubs a voice track into more than 90 languages in the speaker's own voice, but it doesn't sync the lips.

• Meta now translates ad copy, voiceovers and text overlays inside Ads Manager at no extra cost, but only for Facebook and Instagram.

• Translation alone rarely makes an ad feel local. Check imagery, units, holidays and formality for each market, and have a native speaker review ads for markets where you spend the most.

How we ranked

Localizing an ad involves four separate jobs: translating the copy on the image, translating the voice track, changing anything that feels foreign in a market (people, places, holidays, units) and resizing each version for its placements. Few tools do all four. We ranked tools on how many of those jobs they handle, how well the result holds the original layout and brand, how many languages they cover and how easily they scale from one market to many. Prices come from each vendor's pricing page as of October 12, 2026.

The eight tools compared

1. Melius - Best overall for full-market localization

Melius is an agentic image and video generation tool for creators and ad teams.

What works: Melius localizes the whole ad, from the copy to the people in it. Tell its agent, Mel, which markets you need, and it makes a version for each, translating the copy, converting units and currency and swapping scenes and people that need to feel local. Each step runs on the model best suited to it, such as GPT Image 2 for translated text, and every node stays editable. A brand anchor holds rules such as never translating the brand name, and Magic Resize recomposes each image for every placement.

What doesn't: There's no one-click video translation, so dubbing takes a few nodes to set up, and Melius doesn't publish a language count for its voice models.

Best for: Brands and agencies running the same campaign in many markets who want each version to look local, with control over every step.

2. HeyGen - Best for dubbing talking video ads with lip sync

HeyGen is an AI avatar and video translation platform.

What works: Its translator re-voices an existing video in the speaker's cloned voice, with lip sync and subtitles, in more than 175 languages and dialects on paid plans. You can translate into up to 10 languages at once, and a brand glossary on paid plans protects product names and fixes pronunciation. Creator costs $29 a month, or $24 billed yearly, and handles videos up to 30 minutes.

What doesn't: It changes the voice, not the picture, so text burned into the video and culturally specific scenes stay as they are. Editing the translated script needs Pro, every feature draws on one credit pool and Trustpilot reviewers, who give it 4.1 out of 5, complain about credit use and mispronunciations.

Best for: Brands with spokesperson or founder-led ads that need the same ad in many languages.

3. ElevenLabs - Best for dubbing voice tracks in the speaker's voice

ElevenLabs is an AI voice company whose dubbing tool re-voices video and audio.

What works: Automatic dubbing translates into more than 90 languages and accents and clones the original speaker's voice automatically, with uploads of up to 180 minutes in the app. The voices sound natural enough to carry a voiceover-led ad where no one is on camera. Starter costs $6 a month, or $5 billed yearly, and includes a commercial license.

What doesn't: It dubs audio only, with no visual lip sync, so on-camera speakers need a separate lip sync tool. Its Dubbing Studio editor is in maintenance mode, dubbing uses 2,000 to 3,000 credits per minute, which drains Starter quickly, and it doesn't touch on-image text.

Best for: Voiceover ads and teams that want the best-sounding translated voices.

4. Meta Ads Manager translation - Best for free translation inside Meta ads

Meta has added translation tools to Ads Manager for Facebook and Instagram ads.

What works: Multi-language ads translate your ad copy automatically, from English into 16 languages including Spanish, French, German, Hindi and Arabic, and serve each person the right version. In March 2026, Meta expanded AI voiceover translation to more advertisers, added translation for text in image overlays and introduced a flow that translates every element of an ad in a single step. There's no separate fee.

What doesn't: It works only on Facebook and Instagram, availability varies by account, multi-language ads support only single image and single video ads and it only translates, so scenes and people stay the same.

Best for: Advertisers on Facebook and Instagram who want a quick, free first pass.

5. Canva - Best for translating text in static designs

Canva is an all-purpose design platform with AI tools in Magic Studio.

What works: Its Translate feature rewrites the text in a design into more than 100 languages while keeping the layout, including right-to-left languages such as Arabic, and Pro users can translate hundreds of pages a month. Magic Resize then turns each version into other sizes, and video ads can be dubbed into more than 30 languages through the EasyDubbing app inside Canva. Pro costs $18 a month.

What doesn't: It translates text only, so imagery stays the same in every market, longer translations can overflow a tight layout and video dubbing runs through a third-party app.

Best for: Teams that already design their static ads in Canva.

6. Adobe Firefly and Express - Best for Adobe-based teams

Adobe's localization tools are split across Firefly, which translates video and audio, and Express, which translates designs.

What works: Firefly translates video clips of five seconds to 10 minutes into more than 15 languages, several at a time, and Express translates the text in files and templates into 46 languages. Large teams can also use GenStudio for Performance Marketing, which translates approved ads into several languages in one click. Firefly Standard costs $9.99 a month.

What doesn't: Lip sync is only for enterprise customers, Standard includes just six minutes of video translation a month, the features are spread across three products and GenStudio is sold through Adobe's sales team.

Best for: Teams already working in Creative Cloud.

7. The Brief - Best for display and social ad sets in many languages

The Brief, formerly Creatopy, is an ad design and ad serving platform.

What works: Its AI Translate tool translates a design into several languages at once, and you can also localize from a spreadsheet feed with a column per language. When you serve ads through The Brief, it shows each viewer the right language by country or browser language, and you can A/B test ads in different languages. AI Translate is on the Ultra plan, which costs $99 a month, or $79 billed yearly.

What doesn't: It translates only text layers, can't be used on a design that already has a feed applied and has no video dubbing.

Best for: Teams producing display and social ad sets in many sizes and languages.

8. CapCut - Best for cheap translated subtitles and quick dubs

CapCut is ByteDance's video editor for desktop, web and mobile.

What works: Its AI video translator dubs a video in a clone of the speaker's voice with lip sync, and the subtitle translator covers more than 27 languages. That makes it a cheap way to produce a translated cut of a short ad and finish it in the same editor. Pro costs $19.99 a month.

What doesn't: Dubbing is only available in some regions, CapCut doesn't publish its dubbing languages and it works one video at a time.

Best for: Small teams localizing a few short video ads on a tight budget.

How to localize ad creative with AI

• Write a do-not-translate list first: brand and product names, legal lines and taglines that stay in English.

• Decide on formality for each market, such as formal "you" in German and French, and keep it consistent.

• Convert units, currency, dates and seasonal references as well as the words.

• Leave room in layouts, since German and French copy often runs longer than English.

• Resize after translating, then check every version, because a longer line can push a call to action out of frame.

• Have a native speaker review localized ads for markets where you spend the most.

Frequently asked questions

What is the best AI tool for localizing ad creative?

Can AI translate the text inside an ad image?

Yes. Canva, Adobe Express and The Brief translate the text in a design. Melius regenerates the ad with the translated copy rendered in, and Meta now translates text in image overlays inside Ads Manager.

Can AI dub a video ad with lip sync?

Yes. HeyGen and CapCut translate the voice and sync the lips, and in Melius you pair an ElevenLabs voice node with a lip sync model. ElevenLabs on its own dubs the audio only, and Adobe keeps lip sync for enterprise customers.

How many languages do AI dubbing tools support?
