Smartcat extracts the text from every slide element in your .pptx — headings, body text, tables, and speaker notes, which are translated by default — translates it into any of 280+ languages, and writes it back into the same layout.

Paste slide text into a generic translator and you lose the deck:
Smartcat works on the file itself, so the words come out, get translated by your AI agents, and go back exactly where they were.
280+

One source deck, as many target languages as you need — each one exported as its own .pptx.

1,000
Smartwords per image
Text baked into embedded images is not translated with the deck. It runs as a separate image-translation step at a flat 1,000 Smartwords per image, and the translated images go back into the file — worth budgeting on training decks full of screenshots.

Meet with our team and see how the Document Translation Agent handles a deck-heavy workload — glossaries, batch uploads, and a review pass included.
An AI PowerPoint translator is software that translates the text inside a .pptx file while preserving the file's structure, so the output is a working PowerPoint deck rather than a wall of translated text.
Smartcat translates a PowerPoint file's text — headings, body text, speaker notes, and other editable text elements — into any of 280+ languages using your glossary and translation memory, then returns the .pptx with the same slide order, layouts, fonts, and formatting.
Terminology stays consistent across every slide, because the glossary is attached at project level and applies to every document in the project.
Repeated slides or phrases are translated once and reused from translation memory.
One boundary worth knowing before you start: text baked into embedded images is not translated as part of the deck. That runs as a separate image-translation step, and the translated images are re-inserted into the file afterwards.

Upload your .pptx
One deck, several at once, or a legacy .ppt. You can exclude extras such as hidden slides and slide masters at upload.
2
Pick your languages
One source language, as many targets as you need.
3
Download the translated deck
Same layout, new language. Review it first in the Smartcat Editor — or invite a vetted reviewer from the Smartcat Marketplace — if the deck is going somewhere that matters.
Upload the .pptx, pick your languages, and export a deck with the same slides, fonts, and formatting as the original.

Yes, by default. When you upload a PowerPoint file, Smartcat translates the deck's text including headings, body text, speaker notes, and other editable text elements. You don't switch notes on. If you would rather ship untouched notes, delete them before upload — and because notes are spoken-register prose, have a human review them when someone will present from them.
Upload your .pptx to the Document Translation Agent, choose your target languages, then review the draft in the Smartcat Editor or send it to an expert reviewer from the Smartcat Marketplace. Export when you are happy with it and you get a .pptx per language, with the original slide order and formatting.
Smartcat's AI agents support over 280 languages. Your agent learns from your preferences, including tone, slang, and preferred terms, which is perfect for global enterprises to maintain accuracy and brand consistency in all materials.
Partly. At upload you can exclude extras such as hidden slides and slide masters, so anything you have hidden stays untranslated, and you can edit or leave any individual segment in the Document Translation Agent afterwards.
Text in text boxes is translated in place with box position and formatting kept, and table cell text is translated with the table structure intact — check for overflow where the target language runs longer.
Two honest boundaries:
Microsoft's built-in Translator translates selected text on a slide, in place, one selection at a time — useful for reading a foreign deck, impractical for producing one. Smartcat translates the entire file in one pass and gives you a separate translated .pptx per language, with terminology enforced across all of them, plus a review step. Different jobs: reading versus shipping.
You get 15 days free with 15,000 Smartwords and full access to translation capabilities, no credit card required and no free-forever plan. After that it is a paid plan — see pricing plan options. A free tool is genuinely fine for translating one deck once; what you pay for here is the glossary that keeps forty decks consistent, the translation memory that stops repeat charges, and a review workflow.
Smartcat's general upload ceiling is 6 GB per document, and the docs recommend splitting anything over 1 GB, stripping unnecessary embedded media, or compressing images for best speed. Large embedded pictures or videos are a common cause of a deck failing to process. You can start a free trial and test with your heaviest deck.
Smartcat accepts legacy .ppt directly, along with .pptx, .pps, .ppsx, .pot, and .potx — no conversion step needed. Google Slides has its own routes, and Keynote's .key format does not appear in Smartcat's supported-format lists, so plan on exporting to PowerPoint from Keynote first. Beyond presentations, Smartcat's AI agents also handle Microsoft Office files, PDFs, websites, images, audio and video files, and learning content.
You can edit translated text directly in the Smartcat Editor and collaborate with reviewers to ensure quality and brand alignment. This type of AI + human collaboration leads to a positive reinforcement loop, improving the AI even faster.[1] To see an edit in the slide itself, export the deck and open it — there is no target-language preview of a presentation inside Smartcat.
