真实文档实测、诚实的工具对比，以及如何交付一份能直接给客户、给老板、给监管的译稿。
Translate a redlined Word document without losing the revision history. Why most tools flatten tracked changes to plain text, how LangTo keeps insertions, deletions, and comments in the target language, and the honest limits.
Stop a name or a key term coming out three different ways across a long translation. How LangTo reads the whole document first, applies your glossary and built-in regulated termbases, and where consistency still needs your review.
Translate Word, PowerPoint, and Excel files and get the same format back, with tables, images, and tracked changes in place. Step-by-step, plus what each format keeps and where the limits are.
Compare Google Translate, DeepL, and LangTo for scanned PDF translation, including OCR limits, editable Word output, RTL support, and a practical workflow.
