Manage Your Ebook Library with Calibre

// Before you start

What you need

Windows, macOS, or Linux computer
Internet connection
A folder of ebooks (EPUB, MOBI, PDF, etc.) to import — optional but helpful

Step 1 of 6

Download the official Calibre installer

2 min

Calibre publishes ready-to-run installers for every platform. You do not need to touch the GitHub source code at all. Go to the official download page and grab the right file for your operating system.

Terminal · mac

$ https://calibre-ebook.com/download

What you should see

A .exe file (Windows), .dmg file (macOS), or a one-line shell command (Linux) is downloaded or displayed.

This might happen

Browser warns the file is unsafe

This is a false positive. Calibre is open-source and widely used. Click 'Keep' or 'Allow' to proceed.

Step 2 of 6

Install Calibre on your computer

3 min

Run the file you just downloaded. On Windows, double-click the .exe and follow the prompts. On macOS, open the .dmg and drag Calibre to Applications. On Linux, paste the command shown on the download page into a terminal and press Enter.

Terminal · mac

$ sudo -v && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin

What you should see

Installation completes with no errors. A Calibre icon appears in your applications menu or Applications folder.

This might happen

Linux command asks for your password

This is normal. Type your user password and press Enter. Characters will not appear on screen as you type — that is expected.

Step 3 of 6

Launch Calibre and complete first-run setup

2 min

The first time Calibre opens it asks two questions: where to store your library (a folder on your computer) and what ebook reader device you own, if any. You can pick any folder and choose 'Generic' for the device — both can be changed later.

Terminal · mac

$ Open Calibre from your Start menu, Applications folder, or desktop shortcut.

What you should see

A welcome wizard appears asking for a library location and device type. After clicking Finish, the main Calibre window opens.

Step 4 of 6

Add ebooks to your library

2 min

Click the 'Add books' button in the top-left toolbar. Browse to a folder containing your ebook files and select one or more. Calibre accepts EPUB, MOBI, PDF, AZW, CBZ, and many other formats. It copies the files into your library folder automatically.

Terminal · mac

$ Click 'Add books' (top-left toolbar) → browse to your ebook files → click Open.

What you should see

Your books appear as rows in the Calibre book list with title, author, and format columns filled in.

This might happen

Metadata (title, author, cover) looks wrong or missing

Right-click the book → 'Edit metadata' → click 'Download metadata' to let Calibre fetch correct info from the internet.

Step 5 of 6

Convert an ebook to a different format

3 min

Calibre can convert almost any ebook format to any other. This is useful if your reader only accepts EPUB but you have a MOBI file, for example. Select a book, click 'Convert books' in the toolbar, choose your output format from the top-right dropdown, and click OK.

Terminal · mac

$ Select a book → click 'Convert books' (toolbar) → set 'Output format' (top right) to your target format → click OK.

What you should see

A spinning icon appears next to the book. When it disappears, a new format entry is listed under the book's format column.

This might happen

Conversion finishes but the new format does not appear

Click the book once to refresh the detail panel on the right. If still missing, check Jobs (bottom-right corner) for an error message.

Step 6 of 6

Send a book to your ebook reader

2 min

Connect your Kindle, Kobo, or other reader via USB. Calibre detects it automatically and shows a device icon in the toolbar. Select a book, click 'Send to device', and Calibre transfers it in the correct format.

Terminal · mac

$ Connect reader via USB → select a book → click 'Send to device' (toolbar) → choose 'Send to main memory'.

What you should see

The book appears on your device. Calibre shows a confirmation in the Jobs area at the bottom right.

This might happen

Calibre does not detect the device

Make sure the device is unlocked and set to 'file transfer' mode (not charging-only). Try a different USB cable or port.

// the honest bit

The honest part

This guide uses the official Calibre binary installer, not the GitHub source code — building from source requires a full C/C++ development toolchain and is not recommended for non-developers. Calibre cannot remove DRM from ebooks; that is a separate legal and technical matter entirely outside this tool. The newspaper download feature (fetching news as ebooks) requires configuring individual news sources and may break when publisher websites change their layouts.
