An M4B file is the standard audiobook format used by Apple Books, iTunes, and most audiobook players. It uses AAC (Advanced Audio Coding) compression, which delivers smaller file sizes than MP3 at the same audio quality - meaning your audiobooks take up less storage on your device. M4B files also support chapters, bookmarks, and cover art, so you can skip between sections and resume exactly where you left off.

Why use M4B instead of MP3 for audiobooks?

While MP3 files can store basic metadata like title and artist, they don't natively support chapters or bookmarks - so you lose your place every time you close the player, and you're stuck managing dozens of individual files per audiobook. M4B solves all of this: it combines everything into a single file with full chapter navigation, cover art, and bookmark support. It also uses AAC encoding, which produces better sound quality at lower bitrates than MP3, resulting in smaller files that sound just as good or better.

How do I create an audiobook on my iPhone or iPad?

With M4Bindr, just open the app, import your audio files (MP3, M4A, or M4B), arrange them as chapters, add metadata like title, author, and cover art, then tap Build. M4Bindr combines everything into a single M4B audiobook file right on your device - no computer needed.

Can I convert other audio files to M4B audiobooks?

Yes! M4Bindr is designed to convert MP3, M4A, and even other M4B files into a single M4B audiobook format. Import your DRM-free audio files, organize them into chapters, and build a professional audiobook in minutes. When you combine existing M4B files, their original chapters are fully preserved in the new audiobook.

What can I do with the free version?

The free version lets you use M4Bindr as much as you want - there's no time limit or trial period. It does limit the size of audiobooks you can create (up to 30 minutes of audio and 3 chapters), so it's perfect for testing things out and seeing if M4Bindr is right for you before upgrading.

Is there a subscription?

No. M4Bindr Pro is a one-time purchase of $5.99. Pay once and unlock unlimited audiobook creation forever - no recurring fees, no hidden costs.

How do I add chapters to my audiobook?

Each audio file you import becomes a chapter in your audiobook. Simply arrange them in the order you want, name each chapter, and M4Bindr will build a chapterized M4B file that lets you skip between sections in any audiobook player.

Can I add cover art and metadata to my audiobook?

Absolutely. M4Bindr lets you add a title, author, narrator, genre, year, description, copyright, and a custom cover image. All metadata is embedded directly into the M4B file so it displays correctly in Apple Books and other audiobook apps.

Do I need a computer to make audiobooks?

No. M4Bindr runs entirely on your iPhone or iPad. Import audio files from your device, configure chapters and metadata, and build a finished M4B audiobook without needing a desktop app or web service.

How do I get a refund?

All purchases are processed through the App Store. To request a refund, visit reportaproblem.apple.com, sign in with your Apple ID, find the M4Bindr purchase, and follow the steps to submit your refund request. Apple handles all refunds directly.

Can I use M4Bindr on my other Apple devices?

Yes! M4Bindr supports Universal Purchase. If you've already bought Pro access, simply open the app on your other device and tap "Restore Purchases" to unlock it - no need to pay again. It works across iPhone and iPad.

What audio formats does M4Bindr support?

M4Bindr supports DRM-free MP3, M4A, and M4B audio files. This means you can combine multiple M4B files together, or add M4B files to other formats to create a single professional M4B audiobook.

Can I listen to my audiobooks in Apple Books?

Yes. M4B is the native audiobook format for Apple Books. Once you've built your audiobook in M4Bindr, you can share or export the file to a mac where you can sync it to your iphone or ipad and open it directly in Apple Books with full chapter and bookmark support.

Best Audible Alternatives: Building a Free Audiobook Library

Audible isn't the only way to listen. Discover the best free and cheap Audible alternatives, from library apps to public domain archives, and learn how to manage your downloads like a pro.

Audible is the dominant name in audiobooks, but at around $15 a month for a single credit, it is not exactly cheap. The good news is that you do not need a subscription to build a rich, well-organised audiobook library. There are several excellent, and completely free, sources out there. You just need to know where to look and how to manage what you download.

Here is a practical rundown of the best Audible alternatives, from library apps to public domain archives, plus a tip on making all those downloaded files feel as polished as anything you would get from a paid store.

1. Libby (OverDrive), The Best Free Alternative, Full Stop

If there is one app that genuinely rivals Audible for quality and selection, it is Libby by OverDrive. Libby connects directly to your local public library's digital collection, giving you access to tens of thousands of professionally narrated audiobooks, completely free with your library card.

The catalogue includes bestselling fiction, non-fiction, and new releases from major publishers. The main catch is availability: popular titles can have waiting lists, since the library only licenses a limited number of simultaneous checkouts. If you are patient, though, Libby is essentially Audible for free.

2. LibriVox, Thousands of Free Public Domain Audiobooks

LibriVox is a volunteer-run project that records public domain books read aloud by members of the public. Its catalogue spans thousands of classic titles, Jane Austen, Charles Dickens, H.G. Wells, Arthur Conan Doyle, and many more. Every single audiobook is completely free, forever.

The trade-off is production quality. Because recordings are made by volunteers in home studios, narration quality varies significantly between titles. For beloved classics, you can usually find a recording with an excellent reader. For more obscure texts, you may have to make do with what is available.

The other practical issue is the file format. LibriVox distributes books as ZIP folders packed with individual MP3 chapters. Listening to 50 separate tracks on your phone is a frustrating experience, and most default music players have no memory of where you paused.

Fix the LibriVox MP3 Problem:You can convert those messy MP3 folders into a single, beautifully chaptered .m4b audiobook file directly on your iPhone using the M4Bindr audiobook binder. Import the MP3s, add the cover art from the book's Wikipedia page, tap Bind, and you have an Apple Books-ready file with working chapters and bookmark memory, in minutes.

3. Internet Archive, A Massive Vault of Recorded Books

The Internet Archive at archive.org is a non-profit digital library preserving hundreds of millions of files. Its audio section contains a vast collection of spoken word recordings, old radio dramas, and audiobooks, many of which are in the public domain and free to download outright.

Beyond free public domain content, the Archive also operates a Controlled Digital Lending programme that lets you "borrow" digital scans of physical books for a limited period. The selection is enormous and spans both classic and contemporary titles.

4. Project Gutenberg + LibriVox, The Perfect Combo

Project Gutenberg hosts free eBook versions of over 70,000 public domain works. Many of these books have a corresponding LibriVox recording. Using the Gutenberg catalogue as a reference guide to find the best public domain titles, and then sourcing the audio from LibriVox, is one of the most efficient ways to build up a classic literature listening list.

Project Gutenberg also provides some audiobooks directly using computer-generated text-to-speech synthesis. The audio quality is robotic compared to human narration, but it is a viable option when no volunteer recording exists.

5. Spotify, Surprisingly Good for Audiobooks

Since 2023, Spotify has been quietly building out an audiobook library for Premium subscribers. The catalogue already includes hundreds of thousands of titles, and Premium members get 15 hours of listening monthly at no extra cost. Additional time can be purchased in bundles.

If you already pay for Spotify for music, this is an easy way to get audiobooks without adding another subscription. The selection and interface are improving rapidly and it is worth checking whether the titles you want are available before committing to an Audible membership.

6. Storytel, Everand & Nextory, Unlimited Subscription Alternatives

If you do want a paid subscription but are looking for a better deal than Audible's credit system, there are several unlimited-listening alternatives worth considering:

Everand, A flat monthly fee for unlimited access to audiobooks, eBooks, and documents. The catalogue is broad and the value is excellent for heavy readers.
Storytel, Strong in European markets with a massive international catalogue. Offers a generous free trial.
Nextory, Popular in Scandinavia and growing in other markets. Family plan pricing makes it compelling if more than one person in your household listens.

Managing Your Downloads: Turn MP3s into a Proper Library

One thing all the free sources above have in common is the file format: you typically end up with a folder of loose .mp3 files. Listening to these directly is clunky, no bookmarking, no cover art, no chapter navigation, and your music app treating Middlemarch like a playlist.

The proper fix is to convert them to .m4b, the native audiobook format used by Apple Books. An M4B file bundles all your chapters into a single container, embeds your cover art, and gives you perfect pause-and-resume playback. It is the closest you can get to a "store-bought" audiobook experience from a free download.

If you are on an iPhone, the M4Bindr M4B creator lets you do the whole conversion on-device in a few taps, no Mac, no desktop software, no cable needed. Import your MP3s from the Files app, set the chapter order, add metadata, and bind. The result exports directly to Apple Books, ready to listen immediately.

Pair any of the free sources above with this workflow and you have a genuinely premium audiobook experience without ever paying for an Audible subscription.
