How to Upload an eBook to Kindle: Transfer a File or Publish

“Upload an eBook to Kindle” can mean two different things:

• If you want to read a file you own on your Kindle device or app, use Amazon’s Send to Kindle service or another currently supported personal-document transfer method. That places the file in your Kindle library for your authorized personal use. It does not publish the book for sale.
• If you are the author or rights holder and want customers to buy the eBook in the Kindle Store, use Kindle Direct Publishing. Create the Kindle eBook, enter the book details, upload the manuscript and cover, preview the processed result, set territories and pricing, then submit it for publication. Do not use Send to Kindle as a substitute for KDP retailer QA.

Path A: Send a personal eBook or document to your Kindle library

Use this path for your own reading: a manuscript proof, an authorized EPUB, a public-domain book, a report, notes, or another supported personal document.

Step 1: Choose a current Send to Kindle method

Amazon may provide several routes by country, account, device, and operating system:

• Send to Kindle on the web.
• Send to Kindle desktop application.
• Share to the Kindle app from a supported mobile device.
• Send to a registered Kindle email address.
• Transfer by USB for compatible devices and file types.
• Delivery through another authorized Amazon workflow.

Use the official Send to Kindle page to see the methods currently available to your account. Do not assume an old browser extension, desktop utility, or email rule still works.

Step 2: Prepare the personal document

EPUB is a useful format for many reflowable eBooks. Amazon may convert the submitted file for the Kindle reading system. Current supported personal-document types, size limits, and feature handling are listed on Amazon’s Send to Kindle documentation.

For a reliable result:

• Use a valid, unencrypted EPUB or another currently supported file.
• Confirm the title and author metadata.
• Include a navigable table of contents.
• Remove broken external assets.
• Use embedded images at sensible dimensions.
• Avoid fonts or scripts that are not licensed or supported.
• Preserve language and reading order.
• Add text alternatives to meaningful images.
• Check that the source has no comments, tracked changes, or private notes.
• Keep the filename simple and descriptive.

Step 3: Send the file on the web

• 1. Sign in to the Amazon account registered to the intended Kindle device or app.
• 2. Open the official Send to Kindle page.
• 3. Select or drag the supported file.
• 4. Review the displayed title and author information if the interface permits editing.
• 5. Choose the available library or device delivery option.
• 6. Submit the file.
• 7. Wait for processing.
• 8. Open the Kindle device or app, connect to the internet, and sync.
• 9. Check the full library and relevant document or personal-content filters.
• 10. Download and inspect the file.
• The exact labels change. Follow the live interface rather than an old screenshot.

Step 4: Send by registered Kindle email

If your account offers email delivery:

• 1. Open the Amazon content and device settings.
• 2. Find the personal document or Send to Kindle settings.
• 3. Identify the unique email address for the intended device or app.
• 4. Add the sender address to the approved personal-document email list.
• 5. Attach a supported file to a new email.
• 6. Send from the approved address.
• 7. Connect and sync the intended Kindle.
• 8. Check processing or rejection messages in the sending inbox.
• Do not publish the unique Kindle address publicly. Review the approved-sender list and remove addresses you no longer control.

Step 5: Share from a phone or tablet

On supported systems, use the operating system’s share menu and select Kindle. Review the title and author information, choose the available library option, submit, then sync in the Kindle app or device.

If Kindle is not shown, confirm the app is installed, signed into the correct Amazon account, updated, and allowed in the share menu.

Step 6: Use USB only when appropriate

USB transfer can help when a device is offline or a file must remain local, but supported file placement and behavior vary. A file copied by USB may not sync across the cloud library and may appear differently from a Send to Kindle conversion.

• Use Amazon’s device-specific USB instructions. Safely eject the device. Do not place files into random system folders.

Step 7: Find the transferred eBook

A transferred file may be categorized as a personal document rather than an Amazon-purchased book. Interface names vary by device and app.

Check:

• The correct Amazon account.
• All items, downloaded items, and document or personal-content filters.
• The intended profile on a shared device.
• Wi-Fi or mobile data.
• Sync.
• Storage space.
• Date or recent sorting.
• Archived or cloud items.
• Content and device management in the Amazon account.

Worked example: send an advance copy to your own Kindle

A publisher has an authorized, unencrypted EPUB proof named river-stones_v0.9.epub. The metadata contains the correct title and author, the navigation works, and the file has no customer data.

The publisher signs in to the Amazon account registered to a Kindle Paperwhite, opens Send to Kindle, uploads the EPUB, confirms library delivery, and submits. After processing, the publisher connects the Paperwhite to Wi-Fi, syncs, finds the file under the relevant library filter, downloads it, and tests navigation, images, notes, and enlarged text.

Troubleshooting personal Kindle transfer

Problem	Likely cause	Check
File absent	Account, sync, filter, processing	Registration and status
Rejected file	Unsupported, encrypted, corrupt, too large	Exact rejection and current limits
Bad layout	Weak source or print-derived file	Styles and EPUB validation
Missing images	Bad paths or external resources	Package manifest
Wrong title	Source metadata	Library search and file metadata
Email failure	Unapproved sender or wrong address	Account settings
One-device only	USB/local copy or account mismatch	Delivery method and account

Frequently asked questions

Can I upload an EPUB directly to Kindle?

Use Send to Kindle for authorized personal reading and KDP for retail publication. Both may accept EPUB under current rules, but the processing and purpose differ. Check the live official supported-file page.

Does Kindle still require MOBI?

Do not use MOBI as the default new workflow. Amazon’s current personal-document and KDP paths support newer inputs, including EPUB in relevant workflows. Follow current official documentation.

How do I send a book to my Kindle without publishing it?

Use Send to Kindle on the web, a supported app or share route, a registered Kindle email address, or device-specific USB instructions. Sign into the account registered to the device, submit the file, sync, and check personal-document filters.

Why is my transferred eBook not in the Books section?

Personal documents and Amazon purchases can be classified differently. Check all items, documents or personal content, cloud or archived items, and the correct profile. Labels vary by device and app.

Can I upload a PDF to Kindle?

A PDF can be transferred for page-faithful viewing when supported, but small-screen reading may be difficult. For retail eBooks, use the format KDP recommends for the content type; a print PDF is not a universal Kindle eBook.

Current Send to Kindle File Check

Amazon’s Send to Kindle web page currently lists EPUB, PDF, DOC/DOCX, TXT, RTF, HTM/HTML and supported image formats, with a maximum web-upload size of 200 MB. Other transfer methods can have different limits. This limit was checked on October 21, 2026.

Sending an EPUB uses Amazon’s conversion service. Copying the same EPUB by USB is a different workflow and may not make it readable on the device. Use the instructions for the exact Kindle model and file type.

If You Want to Publish for Sale Instead

Use KDP, not personal-document delivery. Create a Kindle eBook, complete book details, upload the manuscript and cover, inspect the processed preview, set rights and prices, decide on Select enrollment and submit for publication. A Kindle eBook does not require an ISBN on KDP.

KDP’s supported-file page lists EPUB, DOCX and KPF for applicable publishing workflows; MOBI upload support has ended. A personal Kindle proof is useful but does not replace KDP’s preview.

Follow the full Amazon eBook publishing guide for account, metadata and royalty decisions. If the file looks broken, repair the source using the manuscript-to-EPUB workflow before sending another version.
