is the future of PDF translation.

Fast, Reliable PDF Translation for Professionals Using XLIFF

TransPDF ends the frustration of translating PDFs by converting them to good quality XLIFF for use with your own translation tools.

Simply upload your PDF to TransPDF and translate the XLIFF you get back using your own tools; the system supports a wide range including memoQ, Phrase TMS and DejaVu. Upload your translated XLIFF and you will get a fully-formatted, translated PDF. Any post-editing can be done for FREE using Infix 7.

In the past, translating PDF documents has been a time-consuming process with translators forced to work with tools that don’t retain formatting, colours or fonts - tools that don't understand PDF. With TransPDF, this is no longer a problem!

This is an amazing technology!!

What Does It Cost?

Purchasing Credits

The cost of producing a translated PDF is just 1-credit per page. With credits costing as little as 15¢ when purchased in bulk, a typical PDF page of 350 words could cost just ¢0.0004 per word!

For example, a 50-page PDF of around 15,000 words could add around €8 to the cost of your project. But how many hours of work would you save? Anyone who has tried editing a PDF will know that putting a translation back into a 50-page PDF would take hours without TransPDF. Isn't your time worth more than that?

Need to Know More?

If you don’t see what you’re looking for, check our FAQ.

Can it handle scanned PDFs ?

Yes. Upload a scanned or 'dead' PDF and TransPDF will convert it to a real PDF with editable text. It then gets converted to XLIFF ready for translation as normal.

Do I have to pay again if I change my translation?

No. You only pay once for a page. After that you can alter the translation as many times as you like without incurring any extra charges.

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.

Can I translate right-to-left language PDFs such as Arabic?

Yes. TransPDF can be used to translate to and from right-to-left PDFs written in Arabic, Hebrew, Pesian and Urdu. By default it also swaps page layout to reflect the reading order of the target language though this behaviour can be disabled.

Are my PDFs secure ?

TransPDF uses industry-standard security measures to stop your PDFs from being seen by unauthorised third parties. However, we cannot be held responsible for the integrity of this data, and documents are uploaded at your own risk.

See the FAQ for further information on document security.

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, Phrase TMS, Fluency, TransitNXT and others.
