Part 3: Tips for Translating PDF

The accuracy of any translation process depends on the tool you choose to use, but also on how you use your preferred tool. The following are some tips to ensure high accuracy when translating PDF documents;

  • Ensure that the document you want to convert is not password-protected. Most translation tools and services are not equipped to handle protected files. If it is, remove the password before translating.
  • Sometimes translation can fail especially if the document contains too many vectors and objects. Removing or flattening the objects can make the process easier.
  • To avoid any problems with links (both hyperlinks and non-linked items), check to make sure that you've added all links to the document before attempting to translate the document.
  • Once the translation is complete, check to make sure that all images with text fields retained their original formatting. It is not uncommon for formats and spacing to be misaligned during translation. Choosing a translator that will not affect the formatting of the document can help.
