Whatever format your deck is in, Smartcat translates it into any of 280+ languages with slides and layouts intact — PowerPoint, a Slides export, a Keynote round trip, or a PDF deck, each with its own route below.
1,000+ enterprise brands rely on Smartcat to translate their decks.
Four routes, depending on what you have.
PowerPoint is the richest format: headings, body text, tables, and speaker notes are all translated as part of the file — notes by default — while text inside embedded images is not, so it has its own page, the AI PowerPoint translator. A long deck goes through in one job rather than slide by slide — see translating a whole PowerPoint at once.
Google Slides — export the deck to .pptx, translate the file, and re-import it into Slides; see Google Slides translation.
Keynote is a round trip rather than a native format: .key does not appear in Smartcat's supported-format lists, so export to PowerPoint, translate, re-import, and check your fonts.
PDF — a deck exported to PDF has no editable text boxes left. The PDF translator returns a translated PDF, not an editable deck, so upload the source file whenever you still have it.
Decks that carry a recorded voice track are a separate job again — the slides and the audio narration inside a presentation are handled on different paths.
280+
Languages, Every Format
PowerPoint, a Slides export, a Keynote export, or a PDF deck — one source file, as many target languages as you need.
20–30%
Longer Target Text
German, French, and Spanish routinely run 20–30% longer than English, which is what overflows a slide designed around English line lengths, or shrinks it via autofit.
1,000
Smartwords Per Image
Text inside screenshots and diagrams is not translated with the deck. Image translation is a separate step, metered at a flat rate per image, and the translated images go back into the file afterwards.

Bring a deck in whatever format you have and we will walk through the route it takes — PowerPoint file, Slides export, Keynote round trip, or PDF.
A presentation translator converts the text in a slide deck into another language while preserving the deck's structure — but what “preserving” means depends on the file format.
PowerPoint and Google Slides — editable formats keep their text in structured elements, so a translator can replace the words inside each text box and table while leaving position and design untouched. In PowerPoint, speaker notes are translated by default along with headings and body text.
PDF — a PDF export has flattened that structure: translation produces a translated PDF, not an editable deck.
Keynote — sits in between, usually traveling through PowerPoint export.
In every format the same three risks apply:
Translated text running 20–30% longer than English and overflowing its space.
Fonts that lack the target language's characters.
Text baked into images, which document translation does not touch.
Smartcat translates all of these formats into 280+ languages and applies one glossary and translation memory across every version of the deck. Three simple steps get you there, whatever format you start from.
1
Upload the file you actually have
A .pptx or legacy .ppt, a Google Slides export, a Keynote export, or a PDF deck. Upload several at once if you have a quarter's worth, and pick the source and target languages.
2
Let AI translate
One source, as many targets as you need. Your glossary and translation memory apply to every file in the project, so the same term lands the same way in each deck.
3
Review & save
Fix any segment in the Editor, then export. An editable file comes back editable; a PDF comes back as a translated PDF. Open one export per language to check that nothing overflowed.
Fifteen days, 15,000 Smartwords, every format — no credit card.
Up to 70%
Lower Translation Cost
Stanley Black & Decker moved from $200–$300 per 1,000 words to $1.20 on L&D content — much of it slide-based — and cut average turnaround by two weeks.
31 hours
Saved Monthly
Babbel's marketing and L&D teams save 31 hours every month.
99%
Accepted Without Changes
Huel accepted 99% of AI translations with no edits, cutting turnaround from 13–18 hours to minutes.
Upload the format you have — PowerPoint, Slides, a Keynote export, or PDF — pick your languages, and get a deck that still looks designed. Free for 15 days with 15,000 Smartwords, no credit card.
Yes. Smartcat translates the deck's text — headings, body text, tables, and speaker notes, which are translated by default — and writes it back into the same layout, using your glossaries and translation memories.
Legacy .ppt is accepted directly, as are .pps, .ppsx, .pot and .potx, so there is no conversion step for an old deck.
Text inside embedded images is the one exception: it is not translated as part of the file.
Upload your deck, choose your target languages, and let the AI produce the draft. Review and fine-tune it in the Editor, then export one file per language. Many languages run 20–30% longer than English, so leave room in tight text boxes and open one export per language before you present.
Smartcat supports 280+ languages and regional variants — including all major European, Asian, Middle Eastern, and African languages, plus regional options like Brazilian Portuguese, Canadian French, and Latin American Spanish. You can translate one PowerPoint into several languages at once from a single upload.
Text is translated in place, with box position, table structure, and formatting kept. Two honest boundaries: text baked into embedded images is not translated with the deck, and complex elements such as SmartArt objects or embedded Excel graphs can cause processing failures — remove or flatten them before upload. Expansion is the thing to check afterwards.
Partly. At upload you can exclude extras such as hidden slides and slide masters, so anything you have hidden stays untranslated, and afterwards you can edit or leave any individual segment in the Editor.
The original, always. An editable file (.pptx, a Slides export) comes back editable; a PDF comes back as a translated PDF, with every element fixed in position. Upload the export only when the source file is genuinely gone.
Export the deck to .pptx, translate the file, and re-import it into Slides. See Google Slides translation and the Google Slides integration for the current options.
Fifteen days and 15,000 Smartwords — full access to translation capabilities, every format, every language, no credit card. There is no free-forever plan; after the trial it is a paid plan, see pricing.
If you have one deck to translate once, a free single-file tool may genuinely be enough. What Smartcat is for is the deck that exists in four formats and twelve languages and has to say the same thing in all of them.
Yes, if they are in the same project. Glossaries and translation memories attach at project level and apply to every document in the project, so the same term translates the same way in each file.
One nuance: a project holds one writable translation memory per language pair, and 103% key-ID matching only applies to formats that carry segment identifiers — standard document formats like .pptx use previous/next context matching up to 102%.
Keynote is a round trip rather than a native format: .key does not appear in Smartcat's supported-format lists. Export to PowerPoint from Keynote, translate the .pptx, and re-import. Check the fonts afterwards — Apple system fonts often have no counterpart on the reader's machine. A PDF deck goes through the PDF translator and comes back as a translated PDF, not an editable presentation.
You can edit translations directly in the Editor and collaborate with your team and reviewers before export. You edit in the segment editor rather than on the slide, though — there is no target-language preview of a presentation inside Smartcat, so export and open the deck to see a change in place.
Smartcat is SOC 2 Type II compliant, with encryption in transit and at rest, isolated workspaces, and role-based access — details on the security page. Strategy decks, board materials, and unreleased product presentations are exactly the content that should not go through a free browser tool with unread terms.
