 #### Should I specify the source language in a request?
 
-If the language of the content in the source document is known, it's recommended to specify the source language in the request to get a better translation. If the document has content in multiple languages or the language is unknown, then don't specify the source language in the request. Document Translation automatically identifies language for each text segment and translates.

 #### To what extent are the layout, structure, and formatting maintained?
 
-When text is translated from the source to target language, the overall length of translated text may differ from source.  The result could be reflow of text across pages. The same fonts may not be available both in source and target language. In general, the same font style is applied in target language to retain formatting closer to source.

 #### Will the text in an image within a document gets translated?
 
-No. The text in an image within a document won't get translated.
+No. The text in an image within a document isn't translated.
 
 #### Can Document Translation translate content from scanned documents?
 
 Yes. Document Translation translates content from _scanned PDF_ documents.
 
-#### Will my document be translated if it's password protected?
+#### Can encrypted or password-protected documents be translated?
 
-No. If your scanned or text-embedded PDFs are password-locked, you must remove the lock before submission.
+No. The service can't translate encrypted or password-protected documents. If your scanned or text-embedded PDFs are password-locked, you must remove the lock before submission.
 
 #### If I'm using managed identities, do I also need a SAS token URL?
 
-No. Don't include SAS token URLS—your requests will fail. Managed identities eliminate the need for you to include shared access signature tokens (SAS) with your HTTP requests.
+No. Don't include SAS token-appended URLS. Managed identities eliminate the need for you to include shared access signature tokens (SAS) with your HTTP requests.
+
+#### Which PDF format renders the best results?
+
+PDF documents generated from digital file formats (also known as "native" PDFs) provide optimal output. Scanned PDFs are images of printed documents scanned into an electronic format. Translating scanned PDF files can result in loss of the original formatting, layout, and style, and affect the quality of the translation.
