First translation free
Upload a PPTX or public Google Slides link. Your first translation is free after Google sign-in, with layout and styling preserved.
Paste a public Google Slides link — no export needed. Get the result back as PPTX or saved straight to Google Slides.
Charts, diagrams and screenshots carry text that file translators skip. Slidelang can translate the text inside your visuals.
No subscription. Your first deck is free, then you buy credits only when you need them.
Proof, not a mockup
Five real PowerPoint files translated by the live Slidelang pipeline. Compare every slide, layout and editable text box yourself.
| Real deck | Text only | Text + visuals | Where alternatives fall short |
|---|---|---|---|
| AI for professionals307 slides · English → GermanOriginal PPTX | 3 credits · $0.60Download result | —Not run — deliberately disabled | At 133 MB, this file exceeds DeepL’s published PPTX limits on its listed plans. PowerPoint leaves media text unchanged; ChatGPT upload is not a quoted whole-deck translation workflow. |
| Anatomy & physiology8 slides · Spanish → EnglishOriginal PPTX | 1 credit · $0.20Download result | 25 credits · $5.00Download result28 candidates · 9 translated · 18 safely kept · 1 unavailable | Nine image labels were translated in place.

No surprise at checkout
Most text-only PowerPoint files cost 1 credit — $0.20 with the pay-as-you-go pack. Larger decks use one credit per started 1,000 passages. Visual translation is quoted separately before any charge.
Your deck is not the product
German hostingThe service runs at Hetzner in Germany, not in an unspecified “cloud”.
Short-lived filesQuotes expire after about 30 minutes; translated download links after about one hour.
The file stays hereThe PPTX archive is never sent to third parties or used for model training. Only extracted text — and eligible images if you enable visual translation — are sent for translation.
DeepL translates PPTX files well, but it needs a subscription, does not accept Google Slides links, and leaves text inside images untranslated. Slidelang covers all three: paste a Google Slides link, translate the text in your charts and screenshots, and pay per deck instead of per month.
Yes. Slidelang rewrites only the text inside your existing shapes, so fonts, colors, positions, animations and slide masters stay untouched. Translated text is refitted so it does not overflow the original text boxes.
Most PowerPoint files translated without images use 1 credit — $0.20 with the pay-as-you-go pack. Your first deck (up to 1,000 text passages) is free after Google sign-in. Visual translation is quoted separately before anything is charged, and no subscription is required.
Your PPTX archive is processed temporarily on servers hosted by Hetzner in Germany and is never sent to third parties. Only extracted text — and eligible images when visual translation is enabled — are sent to configured AI translation providers. Quotes expire after about 30 minutes and download links after about 1 hour. Uploaded presentations are not used to train models.
