Ebook DRM (digital rights management) is copy protection a store applies to the file a customer buys, so the buyer can normally only read it in that store’s own apps and devices. It slows casual sharing, but it does not stop the words being copied. On Amazon, the choice is no longer permanent: you can change it at any time.
What Does Ebook DRM Actually Do?
Ebook DRM, short for digital rights management, is a lock a store applies to the file a customer buys. It does not change who owns the book. The copyright stays with the author either way. What it changes is what the buyer can do with their copy after paying for it.
Each store sets its own restrictions, and they are specific. Barnes & Noble’s consumer documentation for NOOK ebooks is a good example of how detailed they get. For a normal retail purchase it allows unlimited downloads and use on up to six devices or computers, with no copying and no printing.
Read that list again and notice what it describes. Nothing freezes the copy to a single device; it simply stays inside one company’s system. A reader can move a protected book between their own authorised devices. They cannot take it to a device or an app that the store does not support.
No lock can stop someone reproducing the words themselves. A determined person can photograph the pages, run a screenshot through text-recognition software, or simply retype a passage. Tools that strip protection from a purchased file also circulate freely.
US search-volume data from August 2026 gives a sense of how that plays out. Phrases about removing protection from an ebook draw more than 1,000 searches a month between them, comfortably over four times the volume of phrases asking what ebook DRM is and does. It is better understood as friction than as a wall.
Can You Change the DRM Setting After You Publish?
On Amazon’s Kindle Direct Publishing (KDP), the copy-protection setting can be changed at any time after a book has gone on sale. Amazon’s own help page states it plainly: “You have full control over your DRM settings and can change them at any time.” A good deal of published advice still says the decision is locked in at publication, so it is worth knowing which version is current.
A second change arrived alongside it. Since 20 January 2026, a verified purchaser (someone who bought the book, rather than borrowing it) can download an unprotected Kindle ebook as an EPUB or PDF file. EPUB is the standard ebook format that most reading apps accept. Readers collect the file from their Manage Your Content and Devices page on Amazon.
That is the real consequence of choosing DRM-free on KDP today. The buyer ends up with an ordinary file they can read anywhere, including on a device Amazon does not make.
How to change the setting on KDP
You change the setting one book at a time, and only from inside that book’s own record. From your Bookshelf, click the ellipsis button (the three dots) beside the title and choose Edit eBook Content. The Digital Rights Management selection sits in the Manuscript section. Save it, then publish the change from the Pricing page.
Amazon says changes take 24 to 72 hours to reach readers, and that bulk updates are not available. A large back catalogue therefore means working through it title by title.
The wording on that screen repays a second read. The unprotected option reads “No, do not apply Digital Rights Management and allow customers who buy this book to download it as a PDF or EPUB file”. Choosing it opens a confirmation box about customers who have already bought the book. Two negatives in one label make it easy to select the opposite of what you meant.
Two things that catch people out
Two details about timing surprise authors who change the setting on an existing book. Books published before 9 December 2025 that were already DRM-free do not gain the download option automatically. Amazon requires the author to confirm the choice and republish the title before readers see it.
The other detail is that a change only ever applies going forward. Switch a book to DRM-free, then apply DRM again later, and new downloads stop. Readers who already took an EPUB or PDF copy keep the file they have.
Does Every Store Handle DRM the Same Way?
Each retailer decides how copy protection works on its own store, so one ebook sold in five places can carry five different answers. Some stores hand the choice to the author. One documents the limits of its own protection. One publishes nothing about the author’s side of it at all.
Kobo Writing Life gives the author the choice for each ebook individually, and says that enabling it will prevent readers from copying, printing or sharing the book. There is a practical side effect for the reader. With protection on, a customer downloading from Kobo’s website receives a small licence file rather than the book itself. They then open that file in Adobe Digital Editions, a free desktop app, and the EPUB appears.
Apple Books offers an Apply DRM control in iTunes Connect, its publishing dashboard, and documents where its protection stops. Apple states that for an EPUB, the protection applies to the images and the book content. It does not extend to the file’s internal structure, or to any audio and video the book contains.
Barnes & Noble takes a different approach to what it publishes. Its consumer pages describe NOOK protection in detail, but a search of the B&N Press help centre for “DRM” returned no results on 17 August 2026. Nothing published there tells an author whether B&N Press applies protection by default, whether the author chooses, or whether that choice can be changed later. The documentation simply does not say, so check the setup screens in the dashboard or ask B&N Press directly. The rest of how B&N Press works for ebooks is documented much more fully than this corner of it.
What a distribution service passes on
Distribution services add one more layer to all this. A service that sends your file to several stores at once passes on your file and its metadata, meaning the title, author, description and other details attached to the book. Each destination store then applies its own policy at the far end. So copy protection belongs to the shop rather than to your book, just as the file each retailer wants does.
| Where the book is sold | Who chooses | What is documented |
|---|---|---|
| Amazon KDP | The author, per book | The setting, how to change it, and the EPUB/PDF download rule |
| Kobo Writing Life | The author, per ebook | The choice, and what enabling it prevents |
| Apple Books | The author or publisher | The control, and what the protection does not cover |
| Barnes & Noble Press | Not documented publicly | Consumer effects only; nothing author-facing |
| Through a distribution service | Each destination store | Varies by store, not by the distributor |
How Do You Protect an Ebook You Send Out Yourself?
Store copy protection only exists inside a store. When an author hands the ebook file over themselves, none of it applies. That covers two common situations: selling from your own website, and sending a review copy to someone who has agreed to read the book before publication.
It helps to separate two families of protection at this point, because only one of them is available to you here:
- Locking the file. This is what a store does. It encrypts the file, which will then only open inside approved apps. The trade name for this is hard DRM.
- Marking the file. Each copy carries information identifying the person who received it. It encrypts nothing and blocks nothing. Most people call this watermarking, or sometimes social DRM.
Marking is the realistic option for a file you send out yourself. A watermark typically carries the recipient’s email address, stamped on the pages of a PDF or written into the descriptive information inside an EPUB. The file opens in any ordinary reading app, and nothing about it restricts the reader. If that copy turns up on a download site, you can trace it back to the person who received it.
What to do with a review copy
A review copy goes to someone who has agreed to read the book before publication, and it is where this question comes up most. A workable approach has two halves. First, watermark the PDF so you can identify every recipient’s copy. Second, say so inside the book itself.
There are two ways to do that second part. One is a single page at the front stating that this is a review copy and not for redistribution. The other is a short note at the start and end of each part of the text: the front matter (the pages before chapter one), the main text, and the end matter (anything after the last chapter).
The same statement belongs on the rights page, the small-print page near the front that carries the copyright notice. That way the terms travel with the file instead of living only in the covering email. A recipient who forwards the file three months later has usually forgotten the email; the page inside the book is still there.
None of this prevents redistribution. It makes redistribution attributable, which is a different and more modest thing. For a named reviewer who agreed to terms, attribution is generally enough, because the copy is not anonymous.
Selling from your own website
Storefront tools for direct sales offer much the same two levers under various names. One stamps the buyer’s details onto each page of a PDF. The other caps how many times a single purchase can be downloaded. Neither actually locks anything, and the services that provide stamping tend to describe it as a deterrent rather than as DRM.
Genuinely affordable file-locking for direct sales has never really materialised for authors at this scale. What exists is personalised delivery links and watermarking, with no block on passing the file on.
One commercial condition applies before you plan direct sales at all, and it has nothing to do with protection. KDP Select is Amazon’s optional programme that places a Kindle ebook into Kindle Unlimited, Amazon’s subscription reading service. In exchange, the ebook must stay exclusive to the Kindle Store for each 90-day term, so you cannot sell the same digital edition from your own site during that period.
Everything above concerns the copy before it leaves your hands. Working out whether a copy that has already escaped is genuine piracy, a scam listing, or a legitimate reseller is a separate job with separate remedies. We covered how to tell those situations apart in an earlier post.
Does DRM Affect Royalties, Kindle Unlimited, or Accessibility?
Applying copy protection does not change what an author earns. Amazon states that royalty rates and payment structure remain unchanged regardless of the DRM selection. The published royalty terms at the other main stores do not tie payment to it either.
It is not an entry requirement for Kindle Unlimited. What places a book there is enrolment in KDP Select, and the condition attached to Select is the 90-day exclusivity described above. One asymmetry does follow from the 2026 download rule, though: a Kindle Unlimited borrow never counts as a purchase, so a subscriber cannot download the EPUB or PDF of a book even when it is unprotected.
Accessibility is the one place where the choice carries a real cost, and it falls on the reader rather than on the author. The W3C’s EPUB Accessibility Techniques include one titled “Do not restrict access through digital rights management”. Protection can work alongside assistive technology, meaning the software and hardware that people with disabilities use to read. Problems arise when it removes direct access to the file.
The specific failure is worth stating plainly. Unless the reading app lets other software reach the text, it can be difficult or impossible to generate spoken output from the book. So a reader who depends on a screen reader, a specialist reading app, or a braille display may be able to use an unprotected file and unable to use a protected one, even though both contain the same book.
Removing protection does not, by itself, make an ebook accessible. Two things in the file itself matter more: a proper heading structure the reader can navigate by, and written descriptions of any images. Formatting decides both of those, not the upload screen.
DRM is a narrow tool, and knowing what it is narrow about makes the decision easier to live with. It restricts what a paying customer can do with a file. It does not decide who owns the book, what you earn, or whether the words can be copied by someone determined to copy them. On Amazon the setting is now reversible, so this is not a choice you have to get right the first time. For files you send out yourself, marking each copy is the practical option, and it works best when the file itself says what it is.
Frequently Asked Questions
What is a DRM-free ebook?
A DRM-free ebook is one sold without copy protection, so the buyer can move the file between their own devices and reading apps. The book stays fully copyrighted; only the technical restriction is absent. On Amazon, verified purchasers can also download a DRM-free Kindle ebook as an EPUB or PDF file, although titles published before 9 December 2025 need the author to confirm that choice and republish first.
Does DRM stop AI companies from training on my book?
Copy protection is not an AI opt-out, and no retailer’s documentation claims that it is. It cannot cover a book’s public preview pages, a screenshot passed through text-recognition software, or an unprotected edition of the same book sold elsewhere. Reserving AI-training rights is a licensing and contract question rather than a file setting.
Does DRM affect library lending?
Library lending carries its own protection layer, applied by the library platform under its licence terms, and it is separate from the setting chosen for retail sale. A loan has to expire on a set date, so a lending platform applies controls to make that happen even when the retail edition of the same book is DRM-free.
Can a reader share a DRM-free ebook with a friend?
Copying an unprotected file and passing it on is technically possible, in the way that copying any computer file is possible. Copyright and the licence terms still govern what a buyer may lawfully do with it, and technical ability is not permission. Where a store applies protection, the retailer’s own account and device rules govern any sharing.
Should you apply DRM to a free ebook or reader magnet?
A reader magnet is a free ebook offered in exchange for an email address, and it is usually distributed without protection, because the point is to get it read on whatever device the reader already owns. Where a free copy goes to a named recipient, such as a reviewer, a watermark carrying their details gives you traceability without limiting how they read it.
