How to Translate Website Images and Videos for Different Languages

To translate your website's images and videos for different languages, you need to handle two things: the text that appears inside the media (like labels, captions, or on-screen text) and the metadata around it (like alt text and titles). The simplest way is to use a translation tool that automatically swaps images and video subtitles based on the visitor's language. For example, SEATEXT offers free cloud storage for translated images and can automatically replace them on your page for visitors using the matching language. For videos, you'll typically need to provide translated subtitles or captions, and possibly replace the video file if it contains spoken or on-screen text.

What "translating images and videos" actually means

When we talk about translating media, we mean making every visual element on your site understandable to a visitor who speaks another language. This includes:

• Text embedded in images: infographics, screenshots, banners, product photos with labels.
• Alt text and image titles: the descriptive text that screen readers and search engines read.
• Captions and overlays: text that appears on or near the image.
• Video subtitles and captions: the text version of spoken dialogue.
• On-screen text in videos: titles, lower thirds, and graphics.
• Voiceover or dubbed audio: replacing the original audio with a translated version.

Ignoring any of these can leave your international visitors confused or unable to use your site.

The main options for translating media

You have three practical routes:

1. Manual translation: You or a translator create new image files and video subtitles for each language. This gives you full control but takes time and money.
2. Translation management system (TMS): Tools like Weglot or Lokalise help you manage text and media in one place. They often integrate with your CMS and can automate some steps.
3. Automated AI translation: Services like SEATEXT detect the visitor's language and automatically swap translated images and subtitles. This is the fastest option and works well for large sites.

Your choice depends on your budget, the volume of media, and how often you update content.

How to translate images

Here's a step-by-step approach for images:

1. Audit your images: List every image that contains text or needs a localized version.
2. Extract the text: Use OCR or simply read the image to identify the text that needs translation.
3. Translate the text: Get a professional translation or use a machine translation service.
4. Recreate the image: Use a design tool to replace the text in the image. For simple text, you can overlay translated text using CSS or an image editor.
5. Update alt text and titles: Translate these metadata fields for each language.
6. Set up automatic swapping: If your platform supports it, upload translated images and configure them to appear for visitors using that language. SEATEXT, for example, offers free cloud storage for translated images and automatically swaps them based on the visitor's language.

A common mistake is forgetting to update the alt text. Even if the image itself is swapped, the alt text should match the visitor's language for accessibility and SEO.

How to translate videos

Videos are more complex because they have multiple layers:

1. Subtitles and captions: Create a subtitle file (like .srt or .vtt) for each language. Many video players let you switch subtitles automatically based on the browser language.
2. On-screen text: If your video has burned-in text, you'll need to re-render the video with translated text. This is more expensive.
3. Voiceover or dubbing: For spoken content, you can either add subtitles or record a new audio track. Dubbing is usually the most expensive option.
4. Replace the video file: If you have multiple language versions, you can host separate files and serve the right one based on the visitor's language.

For most websites, starting with subtitles is the most cost-effective approach. You can always add voiceover later if needed.

Step-by-step process for a typical website

Here's a practical workflow you can follow:

1. Choose your translation method: Decide between manual, TMS, or automated AI.
2. Set up language detection: Make sure your site can identify the visitor's language (via browser settings, IP, or a language selector).
3. Translate your text content first: Media translation works best when the surrounding text is already translated.
4. Handle images: Create translated versions of images with text, and update alt text.
5. Handle videos: Add subtitles or create localized video files.
6. Test on a real device: Switch your browser language and verify that images and videos change correctly.
7. Monitor and update: When you add new media, make sure it gets translated too.

To verify your work, open your site in an incognito window, change the browser language to a target language, and check that the media swaps correctly.

Key facts about automated media translation

The following table summarizes what you can expect from an automated translation tool like SEATEXT, based on the product's published information.

Limitations and when this advice doesn't apply

Automated translation tools are great for text and simple images, but they have limits:

• Complex graphics: If an image has intricate design or embedded text that can't be easily replaced, you may need a designer to recreate it.
• Videos with spoken dialogue: Subtitles are easy, but dubbing requires professional audio work.
• Legal or compliance content: Some documents need certified human translation.
• Platform restrictions: Not every CMS supports automatic media swapping. Check your platform's capabilities.

If your site has a small number of images and videos, manual translation might be simpler and cheaper than setting up an automated system.

Frequently asked questions

Do I need to translate images and videos separately from text?

Yes. Text translation tools don't automatically handle text inside images or video audio. You need a separate process for media.

What is the cheapest way to translate videos?

Adding subtitles is usually the cheapest. You can create subtitle files yourself or use a service like Rev or Otter.ai.

Can I use Google Translate for images?

Google Translate can translate text in images using its app, but it won't automatically replace images on your website. You'll need to manually update them.

How do I know if my media is translated correctly?

Switch your browser language to the target language and visit your site. Check that images and videos display the correct language. Also test on mobile devices.

Will translating media improve my SEO?

Yes. Localized alt text and captions help search engines understand your content in each language, which can improve rankings in international searches.

How long does it take to translate media?

It depends on the volume. Automated tools can swap images instantly once you upload them. Manual translation can take days or weeks for large sites.

What should I do if my platform doesn't support automatic media swapping?

You can use a translation management system that integrates with your CMS, or manually create language-specific versions of your pages.
