How to send an ebook to Kindle

Send an EPUB or PDF through the Kindle app, Amazon's web uploader or approved email, with a lightweight fallback page for older Kindle browsers.

Use a supported, lawful file

First download the ebook from a route that identifies its source and access terms. EPUB is normally the useful choice for reflowable books; PDF preserves a fixed page. A library loan protected for a particular app is not made transferable just because you can see a local file.

Amazon's Send to Kindle service accepts several document formats and delivers them to the Kindle library associated with your Amazon account. Consult Amazon's current support page for the active format and size limits rather than relying on an old conversion list.

Send the document

  1. On iPhone or Android, open LibreSend's file route or the operating-system share sheet and choose the Kindle app. Confirm the title and add it to the Kindle library.
  2. On a computer, open Amazon's Send to Kindle page, sign in to the account used by the target Kindle and select the local EPUB or PDF. Amazon's current web limit is 200 MB.
  3. For email, send from an approved address to the Send to Kindle address shown for the device. Amazon currently allows up to 25 attachments totalling 50 MB.
  4. Connect the Kindle to Wi-Fi, sync it, and check the Library under documents as well as books.

LibreSend passes the real file to the operating-system share sheet or opens Amazon's official uploader. It does not possess an undocumented Kindle upload API, and the final import remains under the reader's Amazon account.

Use the e-reader fallback page

The public /send page contains a small HTML fallback for older Kindle and Kobo browsers that do not run the full JavaScript interface. It keeps the official Kindle steps, the LibreSend Local command and the Kobo USB fallback readable without depending on modern modules or the site's web fonts.

The fallback is an instruction page, not a hidden delivery channel. Opening a LibreSend Wi-Fi address in a Kindle browser is not treated as a supported Kindle import. Use the Kindle app, Amazon web uploader or approved email route for reliable library delivery.

When it does not appear

  • Confirm that the sending and receiving devices use the same Amazon account and that the Kindle is online.
  • Look for an Amazon processing or rejection message. A malformed EPUB may need a fresh download or a standards check, not a filename change.
  • For a personal, non-DRM file, USB transfer can be useful when the model and computer support it. Follow the current Amazon instructions for that Kindle generation.
  • Do not use conversion tools to bypass DRM. Return controlled loans and purchased protected books to their supported delivery route.
