The Best Ebook Formatting Software for Indie Authors in 2026
Kindles are everywhere. Nooks are still around too. Ebooks are one of the fastest-growing ways people read right now. People are reading on their phones, on the train, in line at the store, during their lunch break, in their car, and at home. Reading on the go is bigger than ever! And what’s the easiest way to do this? With An ebook. As an author, you need to join in on this, but where do you start? You have your book doc, but now you need the right formatting software. There’s specific ebook formatting software that takes your book file and turns it into something compatible on whatever device your readers are on.
Let’s go over which one’s right for you and what’s worth using to get your books into more people’s hands.
What is Ebook Formatting Software?
Ebook formatting software takes your book document and turns it into an ebook file. This covers working chapter breaks, a clickable table of contents, any outbound links in text that resizes according to the screen that it’s on. Think of it as a smart file.
What Is An EPUB File?
Most ebook files are built as EPUB, which is the standard format almost every e-reader uses. (Kindle runs on its own format but now accepts EPUB too) You might think it sounds just like a PDF and might be wondering if you can save your book as a PDF. You can, but most retailers won’t accept a plain PDF for an ebook listing, and even when they do, it’s a bad experience for the reader.
A PDF stays locked to one fixed layout, so on a phone or, say, a Kindle, it can show up small and unreadable instead of resizing to fit the screen. If you use specific ebook formatting software from the beginning, it builds your files in the format retailers require, with the navigation a real ebook needs.
The Best Ebook Formatting Software for Indie Authors
Atticus
Atticus is the tool most people go to first. It’s a one-time purchase of $147 and runs on Windows, Mac, Linux, and Chromebook. It exports a EPUB and print-ready PDF from the same project. All you do is import your book file, pick a formatting theme, and it handles chapter breaks, drop caps, and running headers for you.
There’s no AI writing help built in like other tools but it is the default pick for most authors who aren’t locked into a Mac.
Vellum
Vellum is an ebook and print formatting tool for Mac only. It’s known for its high quality, genuinely beautiful typesetting. The typography controls are more customized than you’ll find with any other tool, and it has a stellar reputation in reviews.
Pricing is a one time fee only
- $199 for ebook only
- $249.99 for ebook and print files
If you want to publish more than one book, it’s one of the better options out there.
Draft2Digital
Draft2Digital is a formatter that also distributes your ebook. It exports your book into EPUB and then sends it straight to retailers like Apple Books, Kobo, and Barnes & Noble. The formatting itself is free, but as of April 2026, D2D added a $20 activation fee plus a $12 annual maintenance fee for accounts that don’t hit a minimum sales threshold.
If you want formatting and distribution handled together, budget for those fees.
Kindle Create
Kindle Create is Amazon’s own free tool, built specifically for formatting a book for KDP. It’s free, super simple, and works if you’re only ever planning to publish on Kindle. There’s not much of a learning curve. The biggest trade-off is that it’s built around Amazon’s own ecosystem, so if you’re wanting to sell your ebook anywhere else besides Kindle, the formatting options are limited compared to a tool like Atticus or Vellum.
Reedsy Studio
Reedsy Studio is a completely free browser-based tool. You can type and write directly in the formatter, or simply upload your book document, and it exports a clean EPUB and print-ready PDF right from the browser with no download required. The template section is limited compared to Atticus or Vellum, and you won’t get the same level of typography control, but for a first book, simple layout, or limited budget, it works
Calibre
Calibre is a free and open-source formatter. It converts between nearly any ebook format you can name and gives deep control over metadata and formatting adjustments. There is a slight learning curve, but for authors who want total control and don’t mind it, it’s hard to beat.
How Do You Choose the Right Ebook Formatting Software?
Ebook formatting software just comes down to what computer you’re on and what you’re willing to spend. The most popular tools on the market right now are Vellum, Atticus, Kindle Create, Reedsy Studio, Draft2Digital, and Calibre.
- Vellum is the top pick for typesetting, but it’s Mac only.
- If you’re on Windows and don’t want to be locked into just one operating system, Atticus gets you close to the same result for less money.
- If you’re only going to publish your book with Amazon KDP, Kindle Create is free and super simple.
- If you want your ebook everywhere, Draft2Digital bundles formatting with distribution. Just factor in additional fees if your book is new.
- If your budget is zero and you don’t need that distribution piece, Reedsy Studio gives you a free EPUB and print PDF.
- If format conversion or detailed metadata control is what you need most, Calibre gets you there for free.
What Comes Before and After Ebook Formatting
Format is going to be sitting in the middle of your book creation process. Before you format anything at all, your book needs to be fully written and edited, and that includes the cover being designed already. Formatting is going to lock in the layout, so swapping anything afterwards means you’re going to be redoing work and potentially moving out your launch date.
Different retailers do want slightly different ebook cover specs:
- Amazon KDP’s size is 1,600 x 2,560 pixels.
- Apple Books wants 1,600 x 2,400 pixels.
- Kobo wants 1,600 x 2,400 pixels.
Create one master cover file, and then resize it and scale it down for other platforms. Once your book is written and edited, you’ll need formatting to turn it into an ebook and a print-ready PDF. From there, you still need a plan for getting the book published. Some tools, like Draft2Digital, handle the distribution as well, so it’s a good idea to weigh the pros and cons of the tool that you choose to use. Some tools also provide both a print-ready PDF and an ebook file, which more than likely will end up saving you money.
Frequently Asked Questions
How much does ebook formatting software cost?
Prices range from free to about $250. Kindle Create, Reedsy Studio, Calibre, and Draft2Digital’s core formatting are free, though Draft2Digital adds fees for accounts that don’t hit a sales threshold. Atticus is $147, and Vellum runs $199.99 to $249.99 depending on whether you need print output too.
What is the best format for ebooks?
EPUB is the industry standard, supported by nearly every e-reader and retailer except Kindle, which uses its own format but now accepts EPUB through Send to Kindle.
How can I format my ebook for free?
Kindle Create, Reedsy Studio, and Calibre are all free. Draft2Digital is also free to use for formatting, though it adds fees for accounts that don’t meet a minimum sales threshold.
What is the best ebook software?
It depends on your computer and your goals. Atticus is the strongest all-around pick for most authors, Vellum leads on typography if you’re on a Mac, and Reedsy Studio is the strongest free option.
Does Kindle support EPUB files?
Yes. Since 2022, Kindle accepts EPUB files through Send to Kindle, email, or USB transfer, and converts them automatically for your device.
Can I format my own ebook, or do I need to hire someone?
Yes, you can format it yourself. Every tool on this list is built for authors, not professional designers, so no coding or design background required. If your book has a simple layout, DIY is usually enough. If it has heavy formatting, like a cookbook, workbook, or illustrated book, hiring a professional formatter is worth considering.
What’s the difference between MOBI and EPUB?
EPUB is the current industry standard, supported by nearly every e reader and retailer. MOBI is the older Kindle-only format that Amazon stopped accepting for new uploads back in 2022, so there’s no real reason to use it today.
