Title and author, written properly
Saved into the PDF's own document properties, in both places readers look for them.
A cover as the first page
Use a photo or an image from your gallery. Fit it with margins or fill the page, and add it as a new page or replace the old first page.
Filename follows the title
The filename updates as you type the title, with characters that cause trouble removed. Turn it off to name it yourself.
Remembers your authors
Authors you have used before appear in a dropdown, and you can remove any of them in Settings.
Your Kindle email, locked
Saved once in Settings and locked until you tap the pencil, so it is not changed by accident.
Share straight in (Android)
Open or share any PDF from your phone into Bookplate in one tap.
Before your first send
Amazon only accepts personal documents from approved addresses. Add the address you send from to the Approved Personal Document E-mail List in your Amazon account, under Content & Devices, then Preferences, then Personal Document Settings. Your Kindle's own email address is on the same page.
