Free PowerPoint Translator Online: Translate PPTX Files Instantly

April 5, 2025 • 3 min read

Looking for a free way to translate your PowerPoint presentations online? Repraze offers 5 free translations with no account needed, and 25 free credits per month with a free account. Here's how to get started.

Translate PowerPoint for Free in 3 Steps

  1. Go to repraze.app and drag your .pptx file onto the upload area.
  2. Select your target language from over 100 options. Source language is detected automatically.
  3. Click Translate and download your translated file. That's it.

What You Get for Free

  • 5 credits without an account — Translate up to 5 slides immediately, no signup needed.
  • 25 credits/month with a free account — Create a free account for 25 credits every month.
  • Full formatting preservation — Free and paid plans get the same quality.
  • 100+ languages — All languages available on every plan.

Supported File Types

Repraze supports:

  • .pptx — Modern PowerPoint format (1 credit per slide)
  • .ppt — Legacy PowerPoint format (1 credit per slide)
  • .docx — Microsoft Word documents (1 credit per 1,500 characters)

Need More Credits?

If you regularly translate documents, Repraze offers affordable plans:

  • Starter: 80 credits/month for €5.99
  • Pro: 300 credits/month for €14.99 (includes API access)
  • Business: 1,500 credits/month for €49.99 (includes API access)

You can also buy credit packs starting at €4.99 for 25 credits if you don't need a monthly subscription.

Why Choose Repraze Over Google Translate?

Google Translate is great for text, but it can't handle PowerPoint files. To use Google Translate with a PPTX, you'd need to manually copy text from each slide, translate it, and paste it back — losing all formatting in the process. Repraze handles the entire file automatically while keeping your layouts perfect.

Ready to Translate Your Documents?

Try Repraze free — no signup required for your first 5 credits.
