What you need to create an ebook

Creating an ebook requires three things: writing software, a way to format your document, and a file format that readers can open. You do not need to buy expensive tools — most people use software they already have, like Microsoft Word or Google Docs, then convert the result to PDF or EPUB format using free tools.

The actual writing happens in any text editor. Microsoft Word, Google Docs, Apple Pages, or even plain text in Notepad all work. The difference comes when you format — adding chapter breaks, images, page numbers, and styling — and when you convert to a file type that ebook readers recognize. The two most common formats are PDF (which looks the same on every device but does not reflow text) and EPUB (which adjusts to screen size but requires more careful formatting).

You will also need a cover image, which can be as simple as text on a colored background or as detailed as a professional illustration. Most ebook platforms provide templates or accept any image file you create in design software like Canva or Adobe InDesign.

Key Takeaways

  • Write your ebook in any word processor you already own — Word, Google Docs, or Pages all work fine for the initial draft.
  • Format your document with clear chapter breaks, consistent fonts, and proper spacing before converting to PDF or EPUB.
  • Convert to ebook format using free tools like Calibre (for EPUB) or your word processor's export function (for PDF).
  • Create a cover image using templates in Canva or design software, or hire a designer if you plan to sell the ebook.
  • Proofread carefully before publishing, because fixing errors after release requires re-uploading to every platform where you distributed it.

Writing and organizing your content

Start by writing your ebook in the word processor you use most often. Do not worry about formatting yet — focus on getting the words down. Most writers find it easier to write in a single document first, then break it into chapters later.

As you write, use your word processor's built-in heading styles to mark chapter breaks. In Microsoft Word, this means using Heading 1 for chapter titles and Heading 2 for subheadings. In Google Docs, use the "Styles" menu to apply the same hierarchy. These styles matter because they become the table of contents when you convert to EPUB, and they help ebook readers navigate your book.

Keep your formatting simple at this stage. Use one or two fonts, stick to left alignment, and avoid decorative elements. Ebook readers display text differently on phones, tablets, and e-readers, so complex layouts often break when the file is converted.

Formatting for ebook conversion

Once your draft is complete, format it for conversion. Set your margins to one inch on all sides, choose a readable font like Calibri or Georgia, and set the line spacing to 1.5 or double-spaced. These settings make the text easier to read on small screens.

Add page breaks before each chapter so they start on a new page. In Word, use Insert > Page Break. In Google Docs, use Insert > Break > Page Break. Do not create page breaks by pressing Enter multiple times — that method breaks when readers adjust text size.

If your ebook includes images, place them within the text where they belong and make sure they are at least 300 pixels wide. Ebook readers will shrink images to fit the screen, but starting with a larger file prevents them from becoming too small to see. Add captions or alt text to images so readers know what they show.

Create a table of contents by hand or use your word processor's automatic function. In Word, go to References > Table of Contents and choose a style. In Google Docs, use Insert > Table of Contents. The automatic version updates if you add or remove chapters later.

Converting to PDF or EPUB format

PDF is the simpler format to create. In Word, go to File > Save As and choose PDF from the file type dropdown. In Google Docs, go to File > Download > PDF Document. The result looks identical on every device but does not reflow text, so readers cannot change font size without zooming in and out.

EPUB is more flexible for readers but requires an extra step to create. The free tool Calibre converts Word documents and other formats to EPUB. Download Calibre from calibre-ebook.com, open it, click "Add Books," select your Word document, then click "Convert Books" and choose EPUB as the output format. Calibre will create a file you can test on your computer or phone before publishing.

After conversion, open your new file in an ebook reader to check it. On Windows or Mac, use a free reader like Calibre itself or Adobe Digital Editions. On a phone, use the Kindle app, Apple Books, or Google Play Books. Look for broken chapter breaks, missing images, and text that does not flow properly. If you find problems, go back to your Word document, fix the issue, and convert again.

Creating a cover image

Your cover is the first thing potential readers see, whether you are sharing the ebook for free or selling it. At minimum, it should include the title, your name, and a visual element — a photo, illustration, or solid color background.

Canva (canva.com) offers free templates for ebook covers in both standard and wide formats. Search for "ebook cover" and choose a template, then edit the text and images. Canva's free version includes thousands of images and design elements. When you are done, download the file as a PNG or JPG image.

If you plan to sell the ebook on platforms like Amazon Kindle or Draft2Digital, check their cover requirements first — they specify minimum dimensions and file formats. Most accept images between 1000 and 3000 pixels wide. A cover that works on one platform may need resizing for another.

Where to publish or share your ebook

You have several options for getting your ebook to readers. If you want to share it for free, you can email the PDF or EPUB file directly, post it on your website, or upload it to free platforms like Project Gutenberg (for public domain works) or Smashwords (which distributes to multiple retailers).

If you want to sell the ebook, Amazon Kindle Direct Publishing (kdp.amazon.com) is the largest platform. You upload your EPUB or PDF file and cover image, set a price, and Amazon handles distribution and payment. Draft2Digital (draft2digital.com) distributes to Apple Books, Google Play, Kobo, and other retailers from a single upload. Both platforms take a percentage of sales and pay monthly.

Some authors use multiple platforms — free PDF on their website, EPUB on Smashwords, and Kindle version on Amazon. Each platform has different formatting requirements, so test your file on each one before going live.

Proofreading and testing before release

Read your ebook on at least two different devices before publishing. Open it on your computer, a phone, and a tablet if you have one. Check that chapter breaks appear where you expect them, images display correctly, and text is readable at different font sizes.

If you are publishing to Kindle, use Amazon's Kindle Previewer tool (available free from Amazon) to see exactly how your book will look on different Kindle devices. This catches formatting problems before readers see them.

Ask someone else to read a copy and report any typos, unclear sentences, or formatting issues. It is much harder to spot your own mistakes. Once you publish, fixing errors means re-uploading the file to every platform where you distributed it, so the extra time spent proofreading saves work later.

Frequently Asked Questions

Do I need special software to create an ebook?

No. Any word processor works — Word, Google Docs, Pages, or even LibreOffice (free). The only specialized tool most people need is Calibre, which is free and converts documents to EPUB format. Everything else can be done with software you already have.

What is the difference between PDF and EPUB?

PDF looks the same on every device but does not reflow text when readers change font size. EPUB adjusts to fit the screen and lets readers customize fonts and spacing, but requires more careful formatting to convert properly. Most ebook readers prefer EPUB, but PDF works fine for sharing with friends or colleagues.

Can I use images and charts in my ebook?

Yes, but keep them simple. Place images within the text where they belong, make sure they are at least 300 pixels wide, and add captions. Complex layouts with images side-by-side or wrapped in text often break during conversion. Test your ebook on multiple devices to make sure images display correctly.

How much does it cost to publish an ebook?

Creating and publishing an ebook is free if you use free tools like Google Docs, Calibre, and Canva. If you sell through Amazon or Draft2Digital, those platforms take a percentage of each sale (typically 30 to 50 percent) but charge nothing upfront. Hiring a professional cover designer or editor costs money, but is optional.

What happens if I find a typo after publishing?

You can fix it and re-upload the corrected file. On Amazon Kindle, go to your bookshelf, select the title, and upload a new version — it usually updates within 24 hours. On other platforms, the process is similar. Readers who already bought the book may need to re-download it to see the fix, so proofreading before release saves this hassle.
