How to Publish an Audiobook on Kobo Writing Life

To publish an audiobook on Kobo Writing Life, create a free account, prepare per-chapter MP3 files and a 2400×2400 px square cover, add a new audiobook from the dashboard, upload your files, disclose AI narration if applicable, set a list price, and submit for review. Kobo pays a 45% royalty and is non-exclusive.

Kobo Writing Life is the self-publishing arm of Rakuten Kobo, a global ebook and audiobook retailer with particularly strong reach outside the United States and into public library systems. Kobo Writing Life lets independent authors publish audiobooks directly, set their own list price, keep a 45% royalty, and reach listeners in Canada, the United Kingdom, Australia, New Zealand, the Netherlands, France, and dozens of other markets where Kobo holds meaningful market share. For authors going wide rather than exclusive, Kobo is one of the core platforms to cover.

How much does Kobo pay in audiobook royalties?

Kobo Writing Life pays a 45% royalty on the list price for audiobooks published through its platform, calculated after applicable transaction fees and taxes. The 45% rate is flat: it does not change with price point, word count, or audiobook length, which makes the math easy to plan around. On a $14.99 audiobook, a 45% royalty returns roughly $6.75 per sale before taxes, paid to the author on Kobo's standard payment schedule.

Kobo's audiobook royalty sits in the middle of the wide-distribution field. ACX pays 50% for exclusive titles and 30% non-exclusive, Google Play Books pays 52% on direct sales, and selling direct from your own website can return 85% or more after platform fees. For a side-by-side breakdown of every platform's payout, see the audiobook royalties explained guide, and for a wider map of selling channels, read where to sell your AI audiobook.

Does Kobo Writing Life accept AI-narrated audiobooks?

Kobo Writing Life accepts AI-narrated audiobooks and does not block synthetic narration the way ACX has historically restricted it. Kobo's policy asks authors to disclose when an audiobook uses AI or synthetic narration during the upload workflow. As long as you hold full commercial distribution rights to the audio and the files meet the technical specifications, an AI-narrated audiobook is eligible for sale on Kobo.

Holding commercial rights matters because some AI narration tools license audio for personal use only. TomeVox grants full commercial distribution rights on delivery with no exclusivity, so audiobooks produced with TomeVox can be published on Kobo Writing Life, Audible, Spotify, and other retailers at the same time. For a detailed look at what those rights cover, see the AI audiobook commercial rights guide.

What does Kobo's international and library reach give you?

Kobo's international and library reach is the platform's strongest selling point for independent authors. Rakuten Kobo holds a leading or significant share of the ebook and audiobook market in Canada, the United Kingdom, Australia, New Zealand, the Netherlands, France, Italy, and several other countries where Audible is less dominant, which means a Kobo listing reaches readers a US-only strategy would miss. An author concentrating only on Amazon leaves these markets uncovered.

Kobo also feeds into OverDrive, the public library lending network now operated as Libby, giving audiobooks published through Kobo Writing Life a path into library catalogues worldwide. Library borrows do not pay the same per-unit royalty as a retail sale, but they build discovery and reader loyalty that a direct-sales-only approach cannot match. For series authors in particular, library availability of book one often drives paid purchases of later books.

What audio file format does Kobo Writing Life require?

Kobo Writing Life requires per-chapter MP3 audio files uploaded in reading order, together with a square cover image. The cover must be 2400×2400 pixels in the RGB color space. Each chapter file should be a clean, individually titled MP3 so the listening app can present an accurate chapter list and resume position.

Kobo's audio specifications overlap with the common professional audiobook specs used by many retailers and aggregators. Meeting those specs gets a file through technical review, but distribution eligibility still depends on each store's AI-narration policy — standard ACX, for example, requires human narration regardless of audio quality. TomeVox produces M4B (a single file with chapter markers) plus per-chapter MP3 output meeting these specifications automatically, including loudness normalization, peak limiting, and per-chapter splitting. Every audiobook is automatically checked for technical quality before delivery, so the files arrive ready to upload to Kobo without manual cleanup.

How do you publish an audiobook on Kobo Writing Life step by step?

Publishing an audiobook on Kobo Writing Life follows a six-step submission flow from account creation to live listing. The steps below assume you already have a finished audiobook file and cover; if you do not, produce those first using the workflow in the AI audiobook production guide.

Step 1: Create a Kobo Writing Life account

Create a free Kobo Writing Life account at the Kobo Writing Life portal, confirm your email, and complete the payment and tax details in your account settings. Kobo cannot pay royalties until your banking and tax information is on file, so finishing this step before you upload avoids delayed first payments.

Step 2: Prepare a distribution-ready audiobook

Prepare your audiobook as per-chapter MP3 files in reading order plus a 2400×2400 px square cover before you start the upload. After your manuscript is produced into audio, confirm the chapter count matches your book and that each file is named in sequence. TomeVox delivers this package within 48 hours, and you can re-generate any chapter at no extra cost if you want a different read on a passage.

Step 3: Start a new audiobook on Kobo Writing Life

From the Kobo Writing Life dashboard, select the option to add a new audiobook, then enter the title, author name, language, series information, and book description. After entering this metadata, choose the categories and keywords that describe your audiobook, because these drive discovery in Kobo's store and library channels.

Step 4: Upload audio files and cover

Upload your chapter MP3 files in reading order and attach your square cover image. After the files finish uploading, review the chapter list Kobo generates to confirm the order and chapter titles are correct, since a mismatch here is the most common reason an audiobook is sent back during review.

Step 5: Disclose AI narration and set your price

Select the AI or synthetic narration disclosure if your audiobook uses an AI voice, then set your list price and choose your distribution territories. After setting the price, decide whether to enable Kobo's library and partner channels, which is recommended for most authors going wide. Disclosure is both an ethical and a contractual requirement, so mark it accurately.

Step 6: Submit for review

Submit the completed audiobook for Kobo's review. After submission, Kobo's team checks the audio and metadata, a process that usually takes a few business days, and the title then goes live on the Kobo store and partner channels. You can edit metadata and pricing after publication without taking the listing down.

Kobo vs other wide audiobook platforms

Kobo Writing Life is one of several non-exclusive platforms an indie author can publish to at once, and each has a distinct royalty and reach profile. The table below compares Kobo's terms against the other main wide-distribution routes.

The key takeaway is that Kobo's 45% royalty is competitive for a wide platform and its international and library reach is the strongest in the group, so most authors publishing wide should list on Kobo alongside Audible, Google Play, and Spotify rather than choosing between them. Because Kobo is non-exclusive, adding it costs nothing but the upload time and only widens your audience.

How long does it take to go from manuscript to a live Kobo listing?

Going from manuscript to a live Kobo Writing Life listing takes roughly one week with AI production. TomeVox produces a distribution-ready audiobook within 48 hours, account setup and upload take well under an hour, and Kobo's review adds a few business days before the title appears in the store. Traditional human narration, by comparison, runs 6 to 12 weeks of casting and recording before any platform review begins.

The cost difference is just as large. AI production through TomeVox costs $49 to $99 at early bird pricing for most book lengths, while a professionally human-narrated audiobook typically costs $3,000 to $8,000 to produce.
