This advanced technology allows for highly customized translation results that can be fine-tuned to meet specific needs.

1. Can I use ChatGPT to translate a PDF?

Yes, you can use ChatGPT-4 to translate a PDF by uploading the file directly for translation. However, if you are using ChatGPT-3.5, you will need to manually copy and paste the content of the PDF for translation. For a more seamless experience, especially with longer documents, consider using software with integrated AI translation capabilities, such as WPS Office.

2. Can Google Translate scanned PDF?

Google Translate is free and can quickly translate editable documents. However, it has limitations when it comes to scanned documents. Google Translate cannot directly translate scanned PDFs. It cannot recognize text if you upload a scanned PDF or an image.
