I can work with all conventional editable formats: DOC/DOCX, XLS, PPT, RTF, TXT, HTML, and XML. In addition, I can use XLIFFs and project files for MemoQ and Trados directly, but I would still ask for a PDF of the original in each case so I can check the context. I can also process files from InDesign in IDML format.
There are additional costs for non-editable files like PDFs, Illustrator files, images (JPEG, PNG, PSD, GIF, etc.), and videos because I have to extract or transcribe the texts first. Please note that I cannot provide finished files from non-editable sources. I will deliver a bilingual document. If you need a ready-to-use file, I need the corresponding raw data. And there will be additional surcharges for DTP.
