The best place to buy ebooks is the store that matches the device you already read on: the Kindle Store for Kindle owners, Kobo for EPUB readers, Apple Books for iPhone and iPad. Before you pay anywhere, though, check your library’s Libby app and know one fact most checkout pages bury: a typical purchase is a license to read a file, not a copy you own.

What You Actually Get When You Buy Ebooks
An ebook is a digital edition of a book, usually an EPUB file or an Amazon format, made to be read on an e-reader, tablet, phone, or web browser. When the Kindle Store, Apple, Google Play, Kobo, or Nook sells you one, the terms of service grant access to that file under a license. Close the account, or lose it, and the access can go with it.
California made this explicit. Its law AB 2426 took effect on January 1, 2025, and requires digital stores selling to California buyers to disclose clearly when “buy” really means a revocable license. That is why some checkout pages now carry a short line saying you are purchasing a license to the content.
Two recent Amazon changes show how the rules shift after you pay:
- February 26, 2025: Amazon removed the “Download and Transfer via USB” option, which had let buyers save a copy of a purchased Kindle book to a computer. Delivery to devices now happens wirelessly.
- January 20, 2026: Kindle began offering EPUB and PDF downloads, but only for books published through Kindle Direct Publishing whose rights holder chose to sell them DRM-free. Kindle Unlimited borrows do not qualify, and most large publishers have not opted in.
Digital Rights Management (DRM) is the copy protection that ties a file to the store that sold it. A title bought in the Kindle Store opens in Kindle apps; the same title from Kobo opens only in Kobo apps. Sellers that skip DRM hand you a file you can back up yourself, and public-domain works from Project Gutenberg carry no restrictions at all.
Where to Buy Digital Books Online: Five Big Stores Compared
Five retailers cover most paid digital book sales in the US, and each one favors a different device.
| Store | Best suited to | Main format | Copy protection |
|---|---|---|---|
| Kindle Store | Kindle devices, any phone or tablet | Amazon’s own | Yes, most items |
| Kobo | Kobo e-readers, library borrowers | EPUB | Yes, most items |
| Apple Books | iPhone, iPad, Mac | EPUB | Yes, most items |
| Google Play Books | Android, any web browser | EPUB and PDF | Varies by publisher |
| Nook (Barnes and Noble) | Nook devices and apps | EPUB | Yes, most items |
Amazon Kindle Store
The Kindle storefront #ad is the largest digital reading store, with apps on iOS, Android, Mac, Windows, and the web. Kindle Unlimited is a separate paid subscription covering a rotating slice of the catalog, weighted toward self-published and small-press work rather than major new releases. Check what a book costs outright before you subscribe for it. Purchases can be paid from an Amazon gift card balance, which makes the Kindle Store an easy gift for a reader.
Send to Kindle accepts unprotected EPUB files and converts them for Kindle devices and apps, so the format gap is narrower than it was. Protected purchases from other stores still will not cross over.
Kobo, Apple Books, and Google Play Books
Kobo is the strongest mainstream option for anyone who wants EPUB and hardware Amazon did not make. Their store runs frequent promotions, and Kobo readers connect to public lending programs directly, which no Kindle device does as cleanly. Apple’s reading app ships on every iPhone, iPad, and Mac and syncs purchases through iCloud. Google’s storefront opens in any web browser, which is useful on a work computer where you cannot install software.
Barnes and Noble Nook and Bookshop.org
Barnes and Noble sells digital editions through its Nook platform, and it is the one national bookstore chain where you can walk in and get help with the account. Browse their Nook storefront online first. The digital newsstand has shifted repeatedly, so confirm what is still available before assuming your favorite magazines are included.
Bookshop.org partners with independent stores. Ordering through their digital section lets you pick an indie shop to receive a share of the sale. Purchases are read in the Bookshop app for iOS and Android or in its web reader, and they will not open on a Kindle, so this is a values purchase more than a convenience one.
Open, DRM-Free Books You Can Keep
DRM-free sellers matter if you want a library that survives a closed account or a switch of devices. Selection is narrower than the big five, and that is the honest trade.
- Humble Bundle sells themed technical and fiction bundles, usually as unlocked downloads.
- Smashwords, owned by Draft2Digital since a 2022 merger, distributes independent authors, many without copy protection. Publisher direct stores, such as those run by Tor and Baen, have long done the same.
- Standard Ebooks rebuilds public-domain texts with modern typography at no cost.
- Open Library catalogs an enormous index of published works with limited lending attached.
- For coursework, this dedicated academic storefront carries academic and professional titles the general stores skip, as do VitalSource and RedShelf.
A quick test before paying anywhere: look for the words “DRM-free” or “unlocked” on the product page. If the listing says nothing, assume the file is locked.
Free Books: Library Apps and Public-Domain Collections
A public library card costs nothing, and it is the cheapest way to read widely. Libby, the library lending service built by OverDrive, connects to your local branch catalog and lends digital titles and audiobooks on a hold queue. Loans expire on their own, so nothing is ever returned late.
Hoopla works differently. Its “Instant” titles borrow right away with no waiting list, but each library sets a monthly borrow limit, and those limits vary widely: some systems allow 15 a month, others cut theirs to 3 or 5 in 2025 and 2026. Newer “Flex” titles can carry holds. Hoopla suits browsing; Libby suits chasing one bestseller. The two catalogs rarely overlap completely, so many readers keep both apps and place holds early on popular new releases.
For older works, Project Gutenberg lists more than 79,000 free public-domain titles, and LibriVox offers public-domain audiobooks read by volunteers. If the author died long ago, search those two first.
Who Gains Most From Digital Books
Commuters, frequent travelers, students hauling course materials, and anyone who needs larger type gain the most. Font size, line spacing, and screen contrast all adjust inside the major apps. A printed page cannot do that.
Storage is the other draw. One e-reader holds a collection that would fill several shelves, and the whole catalog travels in a coat pocket. Fiction readers who finish two or three books a month convert first.
If you read at home in long sittings and like lending favorites to friends, print still wins. Lending is what digital files handle worst.
Image-heavy layouts. Reflowable text works beautifully for novels and poorly for panels and page designs. If you read comics or manga, confirm the store offers a fixed-layout edition.
Why Digital Prices Look the Way They Do
Digital pricing splits into three tiers. Public-domain classics cost nothing. Self-published and small-press work is the cheapest paid tier, because those authors set their own prices. New releases from large publishers sit at the top.
That top tier stays high because of the agency model: major publishers set retail prices directly and stores cannot discount below them. It is why a new hardcover is sometimes cheaper than its digital edition.
Paying more does not buy more rights. A full-price bestseller carries the same license restrictions as a bargain read, so spending up is never a route to ownership. If keeping the file matters, order from a DRM-free seller instead, even at a similar price. Daily-deal newsletters from Kobo, BookBub, and the stores themselves are the practical way to catch temporary discounts on bestsellers.
How to Choose a Store in Four Steps
- Name the device you will read on most. That eliminates half the stores immediately.
- Decide whether you want unlocked files. If yes, shortlist DRM-free sellers first.
- Search your public library catalog for the title. Borrowing costs nothing and tells you whether a work is worth owning.
- Compare price across two stores, then commit to the ecosystem you plan to stay in.
Mistakes That Strand a Digital Library
Committing to one ecosystem untested. Buy two or three titles and live with the reading software for a month. Switching later means leaving those purchases behind.
Paying for public-domain work. Sellers repackage out-of-copyright classics and charge for them constantly. Check Project Gutenberg or Standard Ebooks before you pay for anything old.
Pirate download sites. Beyond the legal problem, files from unauthorized sites carry real malware risk and are often badly formatted or incomplete.
Assuming a purchase is permanent. Treat a licensed collection as access, not property. If a work matters enough to keep forever, get it unlocked or get it in print.
Best Places to Buy Books Digitally, by Reader Type
Ranked by what each does best, not by catalog size. Match one to how you actually read.
Best overall: Amazon Kindle Store. Deepest selection, most reliable apps, most frequent discounts. The trade-off is the tightest lock-in of any major seller. A Kindle Paperwhite is the device most buyers land on.
Best for open formats: Kobo. EPUB throughout, direct borrowing on the hardware, regular sales. A Kobo Clara e-reader is the usual entry point.
Best for files you keep: Humble Bundle and Smashwords. Unlocked downloads, no account dependency, pricing set by authors and publishers.
Best free source: Project Gutenberg and Standard Ebooks. Public-domain works at no cost and with no restrictions. Standard Ebooks wins on presentation because of the typography work behind each release.
Best value overall: your public library. Libby and Hoopla cost nothing beyond a card, and for most readers that beats every paid option on this page.
Set up Libby first, since it costs nothing and settles whether you even need to buy. Then pick one paid store that matches your device and buy two ebooks there before committing further. For anything you want archived, use a DRM-free seller and back the file up the day it arrives. If you still prefer paper, the guide on where to buy paper books covers those options.
Frequently Asked Questions About Ebooks
Who sells ebooks besides Amazon?
Kobo, Apple, Google Play, Nook, and Bookshop.org all sell digital editions to US buyers. Ebooks.com is strong on academic and professional titles, Humble Bundle runs unlocked bundles, and Smashwords distributes independent authors. Publishers such as Tor and Baen have long sold direct from their own sites, which is often where unlocked files come from.
Are eBooks free with Amazon Prime?
Partly. Prime membership includes Prime Reading, a rotating catalog members borrow from at no extra charge. It is much smaller than the full store and the titles change. Kindle Unlimited is a separate paid subscription with a larger pool.
Where can I read e-books for free?
Four legal routes cover almost everything. Project Gutenberg hosts more than 79,000 public-domain works, Standard Ebooks reissues a curated slice of them with better typography, Libby and Hoopla lend current releases through a library card, and Open Library runs controlled digital lending. Free-PDF download sites are none of these; they are unlicensed copies and a malware risk.
Can I move a title I bought from one store to another?
Not if it carries copy protection, which most major-store purchases do. Format converters work fine on unprotected files but cannot open a locked purchase, and circumventing that protection is legally fraught in the United States under the DMCA. Choosing unlocked in the first place keeps your options open.
