How to translate PowerPoint slides with Microsoft Copilot
Microsoft Copilot is an AI assistant that, depending on your subscription, can be used within PowerPoint and other Microsoft products. The PowerPoint version of Copilot helps design and create presentations with AI, including translations.
To get started, click on the multi-colored Copilot icon in the bottom-right corner of PowerPoint. Double-clicking brings up the side pane where you can enter prompts.
- In the Copilot side pane, look among the suggested prompts for a translation option.
- If you don’t see a suggested prompt for translations, type in a prompt with specific details to begin translation. For example, “translate this entire presentation into German” or “translate slides 3-6 into Spanish.”
- Not being specific in the prompt, such as simply saying “translate this presentation into French” might lead to extra steps, especially if it’s a large presentation. For example, only one slide might be translated at a time before Copilot asks if you’d like the entire presentation translated.
- Once you enter the prompt, you can track the progress of the translation.
- Once completed, check formatting and make fixes as needed.
Note: This translation workflow was performed in August 2026 using Copilot’s “auto” mode, which automatically selects the model based on the task.
How to translate PowerPoint slides with thinkcell Assist
thinkcell Assist is a set of presentation AI tools that integrates directly into PowerPoint and Excel. Translations that are applied in-place while maintaining slide formatting are just one capability of this AI solution, which is designed to build on human expertise to improve the effectiveness of slides.
To get started translating your PowerPoint presentation, select the thinkcell Assist icon from the thinkcell tab.
- In the thinkcell Assist side pane, select Translate Slides.
- On the Translate Slides tab, you can choose between Selected Slides or All Slides.
- From the dropdown menu, you can select the target language. More than 70 languages are available.
- Select Translate slides. A progress bar will show you how the translation is being applied to each slide.
Now, your slides are translated with formatting in place. If a section is too long, such as an action title now spanning multiple lines, you can use the shorten text option to reduce length with a single click.
How to translate PowerPoint slides with online translation platforms
Online translation platforms let you upload your PowerPoint file to a website and then download the translated version.
Each of these platforms is a little different, as are the costs associated with the services. To translate a PowerPoint, you typically follow these steps.
- Select the input language (sometimes this is automatically detected).
- Select the output language to translate into.
- Upload the PowerPoint file.
- Download the translated PowerPoint and then make any edits as needed.
While this method can be useful in certain situations, there are some downsides. Comparing your downloaded file with the original can mean a lot of back-and-forth to verify layouts and formatting. Also, you lose version history, which means that if a colleague making edits to the shared file while you’re uploading for translation, you can end up with inconsistencies and having to do duplicate work.
How to manually translate slides with AI chatbots
You can leave PowerPoint and open a browser-based AI chatbot to ask for a translation. This is a manual process and best used for small batches of text or to refine certain sections, as it’s a tedious process requiring copying, pasting, and formatting. Another downside is that the AI doesn’t have the context of your full presentations, while integrated PowerPoint solutions have all the slide and presentation context to ensure better wording.
- Copy the text from a PowerPoint shape or textbox that you want translated.
- Paste the text into an AI chatbot and use a prompt to translate it into your language of choice.
- Copy the output and then return to PowerPoint to paste the text into the original shape.
- Check formatting and make fixes as needed.
One thing to look out for when copying and pasting with this method are potential errors. When working at a fast pace, it’s easy to accidentally copy the entire response or to paste in the wrong textbox.
Translate slides the easy way
Translation is one of the best examples of where AI can remove a substantial amount of manual presentation work. Convenience, however, depends heavily on the tool you choose.
Some tools may introduce extra steps into your workflow and be a potential source of inconsistencies, particularly when working at speed. More integrated solutions benefit from being accessible where your presentation lives and reducing the need for error-prone manual actions.
With the time you save using AI to translate presentations, you can spend less time on manual tasks and more time on critical thinking and meaningful work.
PowerPoint translation FAQ
Here are some common questions about translating PowerPoint slides with AI.
Can AI tools translate PowerPoint slides?

What’s the best way to translate PowerPoint slides with AI?

Integrated tools such as thinkcell Assist, which offers one-click translation capabilities, or Microsoft Copilot can help you save time and focus on the more meaningful aspects of your work.
How long does it take to translate PowerPoint slides with AI?
How long it takes to translate PowerPoint slides with AI depends on the number of slides, size of the presentation, and the tool used. Tools that duplicate the original presentation tend to take longer than tools that translate and replace the on-slide text.
In benchmark testing, a detailed 43-slide presentation was translated from English to French using several different AI tools integrated within PowerPoint. thinkcell Assist was the fastest AI translation tool, taking five minutes to translate the entire presentation. Other AI tools took between eight minutes and 23 minutes to translate the same presentation.

This depends on the tool you use. thinkcell Assist and Microsoft Copilot, for example, offer translations in more than 70 languages.
Can you translate individual PowerPoint slides and not the whole presentation with AI?
Some AI presentation tools, particularly most translation platforms where you upload your original file and download a translated file, only offer the option to translate the entire presentation.
