ePub is one of the most widely accepted eBook formats for online stores, email freebies, and client projects.
The first time I made an ePub, I thought it would be “just export and done.” Reality: an ePub is basically a clean, organized digital book that needs proper headings, spacing, and a working table of contents.
Once I understood that, everything got easier. Though, you can easily create an ePub file online with Reedsy Studio, but there are other tools also that can help you make the similar file.
In this tutorial, I’ll show you multiple beginner-friendly ways to make an ePub file, including how to create an ePub file from Word, how to create ePub online, and how to convert PDF to ePub (with honest warnings, because PDF conversions can be messy).
I’ll also share software and AI tools that can speed up your workflow, especially if you’re creating eBooks for clients, lead magnets, or self-publishing. Let's get started.

What is an ePub eBook, Why it’s different from PDF?
An ePub eBook (short for “electronic publication”) is designed to be flexible and readable on different screen sizes - mobiles, tablets, Kindles, Kobo, and reading apps.
Unlike PDFs (which are fixed-layout and look the same everywhere), most ePub files are reflowable, meaning the text adjusts based on font size and screen width. That’s exactly why ePub is popular for novels, guides, how-to eBooks, and lead magnets.
A reader can increase font size, switch fonts, and read comfortably without pinching and zooming. When someone asks “how to make ePubs,” what they usually need is: clean structure (headings), consistent spacing, proper chapter breaks, a clickable table of contents, and a cover image that displays correctly.
Once you build those basics, your ePub feels professional. Another plus: many platforms prefer ePub uploads over older formats, and modern formatting tools can generate ePub 3 files that work across most stores and devices.
In short, if your goal is a book-like reading experience (not a printable document), ePub is often the better choice than PDF.
Before Creating an ePub: Prepare Your Manuscript
The fastest way to create a clean ePub is to prepare your content properly before you export anything. I learned this after wasting hours fixing a file where I used bold text for headings instead of real heading styles, my table of contents didn’t build correctly, and the chapters looked inconsistent.
So here’s the simple rule: structure first, design second.
Write your eBook in Word/Google Docs/Scrivener, but keep formatting minimal and consistent. Use Heading styles for chapter titles and section headings, keep body text as “Normal,” and avoid manual spacing tricks like pressing Enter 10 times.
For images, use high-quality PNG/JPG, but don’t overdo huge image sizes because they can make your ePub heavy. Also, keep your fonts simple, many eReaders override fonts anyway.
Finally, create clean front matter: Title page, copyright page, and (optional) dedication/intro. When your manuscript is tidy, any tool—online or desktop—will export a better ePub.
Quick checklist (do this once, save hours later):
- Use Heading 1 for chapter titles, Heading 2 for subheadings
- Insert page breaks for new chapters (not multiple Enters)
- Keep images centered and consistent (and compress if needed)
- Remove extra spaces and mixed fonts
- Use simple quotes/apostrophes consistently (helps clean conversion)
How to Create an ePub File
There are different methods using which you can make ePub files. Let's check them out one by one.
Method 1: Create ePub online (Word → ePub with Reedsy Studio)
If you want to create ePub online without installing anything, Reedsy Studio is one of the simplest routes.
It’s made for writing + formatting books, and it lets you export professional eBook files (including ePub).
My personal workflow here is: I finalize the draft in Word/Google Docs, then move it into a formatting tool like Reedsy for clean export. The steps are straightforward: create a free account, start a new book, import or paste your content, and ensure your chapter titles use proper structure.
Then you can export your book by going to your bookshelf, managing the book, and choosing export settings. What I like most is that it feels beginner-friendly, less “technical,” more “author-friendly.” It’s great for client work too because you can quickly regenerate exports after edits.
Step-by-step (simple):
- Create a new book project in Reedsy Studio
- Add/import chapters and apply headings (chapter titles as main headings)
- Check front matter and table of contents
- Preview the eBook layout
- Export as EPUB from the export area
Method 2: Professional ePub Formatting with Atticus or Vellum
If you create eBooks regularly (or you’re offering eBook formatting as a service), tools like Atticus and Vellum can be worth it. Atticus is an all-in-one writing + formatting platform that can export ePub directly, which is super helpful when you want fewer tools in your workflow.
In Atticus, the idea is simple: write/import your manuscript, format using built-in styles, preview it, and export to ePub (and PDF if needed). Vellum is also well known for generating eBook files via its “Generate” flow (commonly used by indie authors and formatters).
From my experience, these tools save time because they handle chapter styling, spacing, and consistency really well.
Instead of fighting with conversions, you focus on making the book look good. If a client comes back with edits, you just update the manuscript and export again, no drama.
The main limitation is platform/cost (Vellum is often used on macOS), but the output quality is usually strong for non-technical users.
Best for:
- Client formatting services
- Books with many chapters/sections
- Authors who want clean exports quickly
Method 3: Create an ePub from Scrivener (Compile → ePub)
If you write long-form content, Scrivener is a powerful writing tool—and it can compile your project into an ePub eBook. The key feature here is “Compile,” where you choose the output type and formatting rules.
Scrivener’s own guidance is clear: go to File → Compile, then pick ePub eBook as the compile format. This is great when your book is already organized in Scrivener (folders for chapters, scenes, etc.).
My personal tip: don’t try to over-design inside Scrivener. Keep your writing clean, use consistent section titles, and let the compile settings do the heavy lifting. After export, always test your ePub in multiple readers because small style differences can show up depending on the device.
Also, if you’re planning to sell on multiple platforms, you may still want to run the ePub through a final check in a dedicated editor (like Sigil) if you notice weird spacing or table-of-contents issues.
Quick steps:
- Organize chapters in Scrivener (each chapter/section labeled clearly)
- File → Compile → choose ePub eBook
- Preview, export, and test the final ePub in reading apps
Method 4: DIY Control (Calibre + Sigil) for Clean Conversions and Fixes
When you want maximum control, especially if conversions look messy, use a combo like Calibre + Sigil. Calibre is famous for eBook management and conversion, and its documentation even recommends converting to EPUB (or AZW3) and then using its editing features to refine the book.
Sigil, on the other hand, is designed specifically to create and edit eBooks using the EPUB format, which makes it perfect for fixing structure, metadata, and chapter formatting.
This is the workflow I use when a client sends me a “difficult” file (like a messy Word doc with random font sizes).
I convert it into EPUB using Calibre, then open the EPUB in Sigil to clean up headings, check the table of contents, and ensure chapter breaks are correct. It sounds technical, but for basic fixes it’s very manageable—especially if you stick to the visual tools and avoid touching code unless necessary.
Simple workflow:
- Convert your source file to EPUB in Calibre
- Open EPUB in Sigil and fix headings/TOC/spacing
- Save, then test in Apple Books/Kobo/Google Play Books
Convert PDF to ePub (Honest Warning + Best Tools)
Many beginners search “convert PDF to ePub” because they already have an eBook in PDF. You can do it, but keep your expectations realistic: PDFs are fixed layout, so conversion quality depends on how the PDF was built.
If the PDF is text-based with simple formatting, conversion can be okay. If it’s image-heavy, multi-column, or designed like a brochure, your ePub may come out messy and require editing.
For quick conversions, online tools like CloudConvert support PDF to EPUB conversions. Tools like FreeConvert and Zamzar also offer PDF-to-EPUB conversion flows, which can be handy when you need something fast.
My personal approach: I use online conversion only when I’m okay doing a cleanup pass afterward. For better results, I prefer converting with Calibre and then correcting issues in Sigil, because I can actually fix the structure instead of re-downloading multiple broken files.
Practical tips for PDF → EPUB:
- If possible, start from Word/Docs instead of PDF
- Convert, then check headings + TOC immediately
- Be ready to fix spacing and image placement in an EPUB editor
Software and AI Tools for Creating ePub
Let’s talk tools, because choosing the right one makes “how to create an ePub ebook” much easier.
For pure formatting, tools like Reedsy Studio (online exports), Atticus (write + format + export), Vellum (generate publishable files), Pages on Apple devices (export to EPUB), Scrivener (compile to ePub), and Kotobee Author (exports to EPUB and more) are all popular options. Kotobee is especially useful if you want interactive/educational eBooks and multiple export formats (including EPUB).
Now, for AI tools: AI usually helps more with writing and drafting than with perfect EPUB formatting. But some platforms combine both.
For example, Designrr (read review) promotes exporting ebooks to formats including ePub, and it also offers “Wordgenie” AI features to generate outlines and initial content.
In real life, my favorite workflow is: use AI to draft faster → edit in my own voice → format in a dedicated EPUB tool for a clean final output.
Create a Clean ePub File (so it looks good everywhere)
Once you’ve exported your ePub, your job is not 100% done. The best-looking ePubs are the ones that follow simple rules, because eReaders are picky and each app renders things slightly differently.
The biggest tip I can give (from painful experience) is: don’t fight the reflowable nature of ePub. If you try to force spacing, fancy fonts, and complex layouts, you’ll get inconsistent results.
Instead, aim for clean structure: consistent chapter headings, readable body text, and simple image placement.
Also, avoid over-styling with too many font changes. Many reading apps override fonts anyway, so your “perfect” font choice may not show up. Keep paragraphs consistent and avoid excessive line breaks.
My go-to ePub polishing checklist:
- Use a clean chapter structure (Heading 1 for chapters)
- Keep images optimized (not huge files)
- Use standard punctuation and clean spacing
- Add metadata: title, author, language, cover
- Ensure clickable Table of Contents works
- Test on at least 2–3 different apps/devices
If you do these basics, your ePub will look professional for both personal projects and client deliveries.
How to Test and Proof your ePub
Testing is where many people skip steps, and then wonder why a client says, “The chapters are not clickable” or “The spacing looks strange on my phone.”
My routine is simple: I test the same ePub in at least two different readers (for example: Apple Books + an Android reader, or desktop Calibre viewer + a mobile app). If I made the ePub using a conversion (especially PDF to ePub), I test even more carefully because conversions often break headings and paragraphs.
If you’re using Calibre, it’s helpful because it’s built for managing and working with eBooks, and it includes tools around conversion/editing workflows.
If I spot issues (like a missing TOC entry or inconsistent headings), I open the EPUB in Sigil and fix structure and formatting directly, because Sigil is made specifically for EPUB editing.
What I check every time:
- Does the Table of Contents list all chapters correctly?
- Do chapter titles start on a clean break?
- Are images aligned properly and not overflowing?
- Do links work (if I added website links/CTA buttons)?
- Does it still look okay when font size is increased?
FAQs about creating an ePub
People usually don’t struggle with exporting, they struggle with getting a clean ePub that works everywhere. So here are the most common questions I get when someone is learning how to make an ePub file or create an ePub file from Word.
My suggestion: treat these like a mini troubleshooting guide. If you’re creating eBooks for clients, these answers also help you explain your process clearly and sound more professional.
FAQs:
1. What is an ePub file?
Answer. An ePub (Electronic Publication) is a flexible eBook format where text “reflows” to fit any screen (mobile, tablet, eReader). Readers can change font size, font style, and spacing easily, unlike PDF, which is fixed-layout.
2. Which is better: ePub or PDF?
Answer. Choose ePub if you want a real “book reading” experience on phones and eReaders. Choose PDF if your eBook has a fixed design (like a workbook, printable pages, or a magazine-style layout). If your eBook is mostly text (guides, stories, tutorials), ePub is usually better.
3. How do I create ePub online for free?
Answer. You can create ePub online using tools like Reedsy Studio. This is beginner-friendly because it doesn’t require installing software.
Wrapping Up
Now you have a clear, repeatable roadmap for how to create an ePub ebook, whether it’s for your own brand, a lead magnet, or a client project.
Please note that every reading app renders ePub a little differently. That’s why you should keep formatting simple and always test before sending to clients.
