You can read Kindle books on Windows and Mac using three methods: the free Kindle app, your web browser, or the Kindle Cloud Reader
The fastest route is the Kindle app for PC, which you read from Amazon and install like any other program. It works on Windows 7 and newer, and on Mac OS X 10.13 and newer. You sign in with your Amazon account, and your library syncs automatically — every book you own appears in the app within seconds.
If you do not want to install software, Kindle Cloud Reader runs in your web browser at read.amazon.com. You get the same library and the same reading experience, but nothing sits on your hard drive. This works in Chrome, Firefox, Safari, and Edge.
A third option is to read directly in your Amazon account on amazon.com, though this is slower and has fewer reading tools than the app or Cloud Reader.
Key Takeaways
- The Kindle app for PC is free, installs in minutes, and syncs your entire library automatically across all your devices.
- Kindle Cloud Reader requires no installation and works in any web browser, but you need an internet connection to read.
- Both the app and Cloud Reader let you adjust font size, background color, and margins, and both save your reading position across devices.
- You can only read books you own or have borrowed from a library through Kindle — you cannot read books from other sources in these tools.
Installing the Kindle app on Windows or Mac
Go to amazon.com, scroll to the bottom of the page, and click "Kindle Apps & Devices" under the Amazon Appstore section. Click "Kindle for PC" (if you use Windows) or "Kindle for Mac" (if you use Mac). The page shows a read button — click it and save the installer file to your computer.
Once the file downloads, double-click it to run the installer. On Windows, click through the prompts and choose where you want the app to live (the default location is fine). On Mac, drag the Kindle icon into your Applications folder. The whole process takes two to three minutes.
Open the app. You will see a sign-in screen. Enter your Amazon email address and password, then click "Sign In". The app connects to your account, downloads a list of every Kindle book you own, and displays them in a grid. Click any book to start reading.
Using Kindle Cloud Reader in your browser
Open any web browser and go to read.amazon.com. Click "Sign In" and enter your Amazon email and password. Your library loads when ready — you see the same books as in the app, organized the same way.
Click any book to open it. The book appears in the center of the screen with reading controls along the top and bottom. You can change the font size, background color (white, sepia, or dark), and margins using the "Aa" button in the toolbar. Your reading position saves automatically, so if you close the browser and come back later, you pick up where you left off.
Cloud Reader works on any computer with an internet connection and a modern web browser. You do not need to install anything, and you do not take up hard drive space. The trade-off is that you must stay online to read — if your internet drops, you cannot access your books.
What books you can and cannot read
Both the app and Cloud Reader show only books you have bought from Amazon or borrowed through Kindle Unlimited or your library's Kindle lending program. You cannot import books you own from other sources — PDFs, ePubs, or books from Project Gutenberg do not appear in these tools.
If you want to read non-Kindle books on your PC, you need a separate reader. Calibre is free and handles most formats. Adobe Digital Editions is also free and works with library books you borrow in ePub format. These are different programs from Kindle and do not connect to your Amazon account.
Adjusting text size, fonts, and colors
In both the app and Cloud Reader, click the "Aa" button (or "Text" button in some versions) while reading. A menu appears with a slider to increase or decrease font size. You can also choose the typeface — most versions offer serif and sans-serif options.
Below the font controls, you see background color choices: white (standard), sepia (warm beige), and dark (dark gray or black). Dark mode is easier on your eyes in low light. The app remembers your choices and applies them to every book you read.
Line spacing and margins can also be adjusted in the same menu. Wider margins and more space between lines make text easier to read on a large monitor.
Syncing your reading across devices
When you read a Kindle book on your PC, the app or Cloud Reader records how far you have read. If you then open the same book on your phone, tablet, or another computer, it jumps to the same page. This sync happens automatically within a few seconds of closing the book.
This works because your reading position is stored on Amazon's servers, not just on your device. As long as you sign in with the same Amazon account on each device, you can pick up where you left off anywhere. You can also see your reading progress as a percentage at the bottom of the screen.
Troubleshooting common problems
If the app will not open or crashes when you try to read, restart your computer first. If that does not work, uninstall the app, restart again, and reinstall it from amazon.com. This fixes most problems with corrupted files or outdated versions.
If your books do not appear in the app after you sign in, check that you are signed in with the correct Amazon account — the one you used to buy the books. If you have multiple Amazon accounts, books purchased under one account do not show up when you sign in with another. Sign out and sign in with the right account.
If Cloud Reader is slow or does not load, clear your browser cache and cookies, then refresh the page. If you are using an older browser, update it to the latest version. Cloud Reader works best in current versions of Chrome, Firefox, Safari, and Edge.
Frequently Asked Questions
Can I read Kindle books offline on my PC?
Yes, but only with the Kindle app, not Cloud Reader. The app downloads books to your hard drive, so you can read them without an internet connection. Cloud Reader requires an active connection at all times.
Do I need to buy a Kindle device to read Kindle books on my computer?
No. The app and Cloud Reader work on any PC or Mac. You do not need a Kindle e-reader, tablet, or phone. You only need an Amazon account and the books themselves.
Can I highlight and take notes in the Kindle app?
Yes. Click and drag to select text, then click the highlight button. You can choose the highlight color. Notes appear in a sidebar and sync across all your devices. Your highlights and notes are stored in your Amazon account.
What happens if I uninstall the Kindle app?
Your books stay in your Amazon account. When you reinstall the app and sign in, your library reappears. Nothing is lost. You can reinstall and uninstall as many times as you want.
Can I read library books through Kindle on my PC?
Yes, if your library offers Kindle lending. Check your library's website for a link to their digital collection. You borrow the book the same way you borrow a physical book, and it appears in your Kindle library for the loan period. After the loan expires, it disappears automatically.
