How TransPDF works

Translating PDFs used to mean stripping text and formatting from a PDF, recreating the layout imperfectly in a separate editor, and spending hours trying to ensure everything looks right.

TransPDF is a 4-step process producing translated PDFs of the highest quality while streamlining your workflow:

  • 1

    Upload the original

    Upload your original PDF – TransPDF will extract the content from any number of pages and instantly convert it to XLIFF

  • 2

    Translate the XLIFF

    Your existing tools (SDL Trados Studio, MemoQ, Memsource, DejaVu or others) understand XLIFF allowing for fast, reliable translation

  • 3

    Upload the translation

    Upload your translated text and TransPDF will provide a clear preview retaining your original formatting and flagging up any font issues created during translation

  • 4

    Download your final PDF

    Download your final PDF document, which can then be polished using any PDF editor. We recommend using Infix 7 not just because it's free for TransPDF users but because it offers additional font-checking for translated PDFs.

PDF translation for the 21st Century

Document authors and translators can now translate the largest, most complex PDFs in minutes.

No Software Required

The conversion from PDF to XLIFF is handled by our servers, meaning there’s no additional software, no updates and no maintenance fees. All you need is a web browser and your PDF.

Use your own translation tools

TransPDF works alongside your own translation tools (SDL Trados Studio, MemoQ, Memsource, TransitNXT, etc). Your tools handle the translation, it handles the PDF formatting and conversion.

No on-going fees

You only pay for TransPDF when you download your final, finished PDF. You won’t pay a monthly fee, and your first 25 pages are absolutely free.

As a TransPDF user, any clean-up required of your translated PDF is free-of-charge when you use Infix PDF Editor 7.

The Future of PDF Translation is Here

TransPDF was designed with translators in mind. You can still use your tried and trusted CAT tools, but you don’t need to rebuild your PDFs by hand.

There’s no need to convert your work to a plain-text or Microsoft Word format, and you aren’t forced to create a new PDF from scratch, having lost your initial colours, fonts and layout.

TransPDF does the hard work, streamlining your workflow and leaving you with only a small amount of tidying and editing which can be done free-of-charge using Infix 7.

A process that used to take hours can now be accomplished in minutes.

Share Your PDF Quickly and Easily

TransPDF lets you share your PDF with a number of translators, allowing you to translate the original into a range of languages at the same time. Each translator can upload the new text and access previews, but only you can generate the final, fully-translated PDFs.

TransPDF makes it simple to make PDF your format of choice, retaining corporate colour schemes and locking in spot-colours, layouts and fonts to ensure a coherent brand identity.

  • Translate your PDF into a range of languages at the same time
  • Share each target language with a specific expert translator
  • Monitor the progress of the project at every stage
  • Download previews of any translations whenever you need to
  • Upload corporate fonts, ensuring coherent branding

Is there a public API available?

Yes. There is a fully documented API you can use to integrate smart PDF translation into your own applications for free.

The API package consists of a Python demo showing how to access all of the features such as uploading PDFs and exporting XLIFF. The underlying technology is HTTP-based so you don't need to use Python if you don't want to.

What is XLIFF ?

XLIFF is an industry standard XML-based format for translating all kinds of documents and is supported natively by leading tools such as SDL Trados Studio, MemoQ, Memsource, Fluency, TransitNXT and others.

Can anyone else see my PDFs ?

When you upload a PDF it is visible to you and only those whom you choose to share it with. Access to is all done via https (secure web access) which means your passwords and data are encrypted during transit.

Can it handle right-to-left text such as Arabic?

Not yet, unfortunately. TransPDF can only handle languages written left-to-right. Some vertical text is also supported. This means the system is currently not suitable for Arabic, Hebrew etc.
