Send to Kindle features on Windows put a personal document in your Kindle library. You can then read it on a Kindle or in the Kindle app, with reading progress, notes, highlights, and bookmarks. The Windows app is one of several official send paths Amazon lists.
The Windows page says the app adds personal documents, web content, and other files to your library. Archived personal documents can be downloaded again on a Kindle device or with the free Kindle app on iOS or Android. That wording is in the package description for version 1.1.1.260.
Send a file to Kindle from Windows after you install Send to Kindle for PC.
The Windows page names reading progress, notes, highlights, and bookmarks as library features. The package description is more specific: Whispersync of notes, highlights, bookmarks, and last page read is available on archived personal documents that have been converted into Kindle format.
Documents that stay in the original file, or that were sent before 11 November 2022, do not get every newer markup feature. Amazon’s conversion help says to import them again through Send to Kindle.
Amazon’s help page says documents sent through Send to Kindle are protected with end-to-end encryption, and that the service sends them to your Kindle library and Kindle app at no additional cost. The hub also says you must be signed in to your Amazon account.
