I recently translated a 130-page report using
https://pdft.ai/translate-large-pdf/ and it was smooth from start to finish. The upload was quick, and the tool preserved tables and chart positions without scrambling them. You can download the output as a DOCX if you need to tweak something, or as a PDF if you want it ready to send. The translation speed was much faster than I expected for a file that size. Definitely saved me hours compared to breaking it into parts.
