Document translation is increasingly important in the globalization age as more and more people from different countries work together through Internet. However, translating PDF documents is still challenging. Not as easy as you can do with an editable Word file, the text in a PDF can not be edited, or be copied in many cases. Then how do you translate a PDF with minimal effort?

Thanks to some PDF to Word converters and PDF editors like SwifDoo PDF as well as effective PDF translators, translating PDF files has never been this easier. This post will introduce how to translate a PDF from one language into another easily using PDF editing software and a PDF document translator.

Translate a PDF with PDF Software

As a translator employed by a company, you may want to translate documents yourself to ensure the translation quality, instead of using machine translation. In this case, if you need to translate a document in PDF format, it’s necessary to convert the PDF to a searchable and editable Word file so that you can directly start the translation under specific text. Besides, even if you use the machine translation, it may not help with scanned PDFs, thus converting PDF to Word with PDF software is necessary.

In addition, when it’s not necessary to translate an entire PDF page or create translations in another file, you can use PDF software to directly edit the PDF to write your translated sentences or paragraph.
