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, Memsource 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. In short, tools that don't understand PDF. With TransPDF, this is no longer a problem!

This is an amazing technology!!

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.

The facility is also available via the Memsource integration though not yet with the plug-in for SDL Trados Studio.

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 wan to.

Are my PDFs secure ?

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.

If your clients insist of total security, we offer the TransPDF Appliance.

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 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.
