Key Notes

The formatting and layout of the original document will be preserved after translation. PDF files can optionally be downloaded in .docx format for easy subsequent editing. IDML files will generate a fully compatible InDesign file after translation. JSON file translation preserves the original key names and structure, only translating the value text.

To translate other formats, please contact the DeepL sales team for customized solutions.
