Professional eBook Conversion Since 2008

Hand-Coded eBook Conversion Services for Authors and Publishers

You spent months writing your manuscript. It deserves better than an automated converter that bloats your code, fails KDP validation, and quietly breaks every footnote link in the book. Our eBook conversion services mean we hand-code your file instead — line by line, in HTML and CSS, to your platform's current spec. Delivered in 72 hours. Source files yours to keep. Lifetime warranty on defects.

Why Professional Authors Choose Our eBook Conversion Services

Most automated converters produce files that pass a surface-level check but fail in practice — bloated code, a table of contents that links to the wrong chapters, footnotes that display as blank pop-ups on Kindle, images that look correct on a laptop but render as narrow slivers on a Kindle Paperwhite, cover images embedded at the wrong dimensions for Apple Books. We have fixed thousands of these files. We do not produce them.


Hand-Coded, Not Automated

No Calibre. No Sigil export. No conversion software of any kind. We open your manuscript and build your eBook file in HTML and CSS from scratch. This takes longer. It produces a smaller, cleaner file that passes every platform’s validation and displays correctly on every device.

PDF Comparison Accuracy Check

For PDF source manuscripts, every page of the converted output is compared against the original using professional PDF comparison software — catching cut text, missed paragraphs, spacing errors, and any content that did not transfer cleanly. Almost no conversion service includes this step as standard.

EPUBCheck Validated — Zero Errors Before Delivery

We validate every ePub with the current production release of EPUBCheck — 5.3.0 today — the official W3C conformance checker, against the EPUB 3.3 specification. You receive a file with zero errors and zero warnings. Not “passes most checks.” Zero.

Original Styles Retained

Your formatting — chapter headers, drop caps, first-line indentation, blockquotes, callout boxes, special paragraph styles — is preserved exactly as intended in your source file, within the published specification of each output format. We do not impose a default template on your work.

What Our Kindle and ePub Conversion Delivers

72-Hour Guaranteed Delivery

Your converted file is delivered within 72 hours of receiving your manuscript — guaranteed, or your money back. Most standard orders are delivered within 48 hours. The 72-hour window is the guarantee, not the average. Need it faster? 24-hour rush delivery is available as an add-on at checkout.

Free Source Files — Included Always

Your complete HTML and CSS source files come with every order at no extra charge. Many services withhold source files or charge extra for them. They are yours. Archive them, edit them yourself, or pass them to a developer. We include them because they belong to you.

Lifetime Warranty — Free Fixes Forever

Find a defect in a file we built — today, next year, in 2032 — and we fix it free. No expiry. No claim form. Just email us.

To be clear about the boundary: the warranty covers our errors, permanently. Changes you want later — new content, a retitled chapter, a redesign — are separate work. One revision pass is included with every order for anything that is not right on delivery. We have not found another service offering an unlimited-term defect warranty.

One Manuscript, All Formats Simultaneously

We convert one manuscript into Kindle KPF, ePub, and KDP Print PDF simultaneously in a single project. One upload, all three formats, one delivery within 72 hours. Our Kindle + ePub bundle saves you $20–$160 on the combined price.

Retailer and Platform Ready — Every Time

Complete Metadata for Retailer Discoverability

Every eBook we deliver has complete metadata embedded — title, author, ISBN, series, language, publisher, and subject categories — so your book is indexed and findable in retailer search from the moment it goes live. Incomplete metadata is among the most common reasons eBooks fail to appear in retailer search results.

Accepted by All Major Retailers — Guaranteed

Amazon KDP, Apple Books, Kobo, Google Play Books, Barnes and Noble, IngramSpark, Draft2Digital. If any of these platforms reject your converted file, we identify the specific error in the underlying code and fix it — included in every order at no charge.

Cover Image to Platform Specifications

Your cover image is embedded to the exact pixel specifications of your target platform — Amazon KDP 1,600 x 2,560px (width x height), Apple Books minimum 1,400px on the shorter axis, Kobo portrait at roughly 3:4. Displays correctly on every screen — from a 6-inch e-ink Kindle to a retina iPad — without distortion, cropping, or resolution loss.

Formatted to Current Industry Standards

Every file is built to the current published specification of its target format — ePub per the W3C standard, Amazon KPF guidelines per current KDP documentation, and IngramSpark’s current preflight requirements. ePub 3 available on request. Not a generalised template. The current standard.

Why Authors Trust Us With Their Manuscript

Your Manuscript Stays Confidential

Your manuscript is unpublished work and we treat it that way. Files go over encrypted transfer, stay on access-controlled systems, and are never shared, resold, or used to train anything. We sign an NDA on request, before you send a single page.

No Royalties. You Keep 100%.

You pay once. We take no percentage of your sales, now or ever, and we claim no rights over your book. Some formatting services and hybrid publishers do take a cut. We do not.

You See the Test Results

As we test your file, we record what we find and send it to you. You are part of the proofing loop, not waiting outside it. If a device throws up something odd, you will know before you publish.

From Manuscript to Published eBook in 4 Steps

Step 1

Choose Your Service

Browse our service categories and select the format you need — Kindle, ePub, KDP Print, Fixed Layout, or a bundle. Complete checkout in under 2 minutes. Use the order notes field to tell us anything specific about your manuscript before we start.

Step 2

Upload Your Manuscript

Your order confirmation email includes a secure upload link. Send us your file in any format — Word, PDF, InDesign, Pages, HTML, or a scanned book. You do not need to reformat it first. Send us exactly what you have.

Step 3

We Hand-Code Your eBook

We open your manuscript and read it first. Then we build your eBook file from scratch in HTML and CSS. No automation software — at any point. If we have a question about your formatting, we email you. Your 72-hour clock starts the moment we receive your file.

Step 4

Receive Your Files and Publish

Your converted file, complete source files, and a quality report arrive in your inbox within 72 hours. Open your file in Kindle Previewer or an ePub reader and review it. If anything needs adjusting, reply to the delivery email — one revision pass is included in every order. Need help getting it uploaded to your store? Just ask — we’re glad to help with that step too.

What Every eBook Conversion Includes

These are not premium add-ons. They are not features reserved for higher-priced packages. Every conversion we complete — from a $20 error repair to a $125 complex multilingual manuscript — includes everything listed below, delivered as part of the standard order.

Structure and Navigation

Clickable Table of Contents

Your ePub ships with both navigation files. The EPUB 3 Navigation Document, which the spec requires. And a legacy NCX, so older EPUB 2 readers still show a working contents list instead of nothing. You also get a visible HTML contents page inside the book. Every entry links to the right chapter. We check them one by one.

Active Hyperlinks, Footnotes and Endnotes

Every hyperlink stays clickable in the converted file. Footnotes become Kindle pop-up notes — the format Amazon intends. Endnotes become linked references for ePub. You choose which format you want. Just add your preference in the order notes.

Embedded Licensed Fonts

Have a specific font and the licence to embed it? We embed it correctly so it shows on every device. No font? We set the right font-family stack. Readers can pick their preferred typeface. The layout never breaks.

Metadata and Retailer Discoverability

Complete Metadata — NCX, OPF, and Full Bibliographic Data

Your title, author, publisher, ISBN, series, language, and subject categories go into the OPF and NCX metadata files. Retailers use this data to index and surface your book in search. Incomplete metadata is among the most common reasons eBooks vanish from retailer search results. We get it right.

Cover Image at Correct Retailer Specifications

Every platform has exact cover image requirements. Amazon KDP wants 1,600 x 2,560px — width by height, portrait, 1.6:1. Apple Books wants a minimum of 1,400px on the shorter axis, in RGB. Kobo wants portrait, roughly 3:4, under 5 MB. We embed your cover to the right spec for each platform. It displays cleanly on every device — from a 6-inch e-ink reader to a 12-inch iPad.

Quality, Validation and Compatibility

Strict Quality Assessment Including PDF Comparison

After conversion, a specialist reads your eBook against the original. For PDF source files, we run a PDF comparison check. It catches cut text, missed paragraphs, and spacing errors. We also check footnote links, image placement, TOC accuracy, and chapter headings. Nothing leaves until it is right.

Full Compatibility — Every Major Device and Platform

We test your file on the devices your readers actually use — Kindle Paperwhite, Kindle Scribe, Kindle app on iOS and Android, Apple Books on iPad, Kobo Clara, and Android e-reader apps. We check the visual output — not just the file structure. Passes validation is not enough. It has to read correctly too.

Print-to-Digital Conversion, Checked by a Human on Every Page

See our full Book Scanning & OCR service for physical books and existing scans.

Human-Verified OCR

Most conversion houses run a scanned book through an automated OCR engine, run a second automated pass to catch the obvious errors, and ship it. That is where the mistakes get baked in, because no one ever reads the result against the original. Our OCR process is our own, and it depends on human interaction rather than automation. A person checks every single page against the source.

We Have Caught Errors in Printed Editions

We have found and reported mistakes in clients’ printed books this way — typos their own proofreaders missed, in editions already on sale. Have the original Word or InDesign file instead? Send that. Export beats OCR every time, even when the file was never built with eBooks in mind.

Content Other Converters Send Back

Equations and chemical formulae. Poetry, where the line breaks and indentation have to survive reflow. Tables that must stay readable on a phone. Q&A and workbook formats. Footnote-heavy academic text. Classical scripts alongside modern ones. Poetry and chemical formulae are the two things automated conversion reliably destroys, and most services quietly decline them. Send them to us.

We Convert eBooks in Any Language — Including Right-to-Left Scripts

Arabic, Chinese Simplified, Chinese Traditional, Japanese, Korean, French, Spanish, German, Italian, Portuguese, Hindi, and more. Right-to-left and non-Latin scripts need specific HTML and CSS handling. Automated tools get this wrong. We do not.

Who We Are Not For

We are not the cheapest. A five-dollar gig converter will take your file, run it through Calibre, and have something back to you within the hour — and if your book is straight narrative prose with no images, no footnotes and no tables, that may honestly be enough for you.

We are not for that job.

Come to us when the file matters.

Complex layouts. Footnotes and endnotes. Tables, equations, embedded fonts. Non-Latin scripts. Accessibility obligations. Anything a retailer has already rejected once.

eBook Conversion Services — Frequently Asked Questions

72 hours from when we receive your manuscript, guaranteed, or your money back. Most standard orders finish inside 48 hours. A 24-hour rush option is available at checkout.

Automated tools apply one template to every manuscript, which is why they produce bloated markup, broken footnote links, tables that collapse on a phone screen, and images that look fine on your laptop but render as narrow slivers on a Paperwhite. Hand-coding means a person reads your book and writes the HTML and CSS for it. Smaller file. Clean validation. And it displays correctly on the devices the automated version breaks on.

Yes, with every order, at no extra cost. You receive the complete HTML and CSS. They are yours to keep, edit, or hand to another developer.

Word, PDF, InDesign, Pages, HTML, plain text, Google Docs, or a scanned book. Do not reformat anything first. Send it as it is.

Yes. If KDP, Apple Books, Kobo, Google Play, Barnes and Noble, IngramSpark, or Draft2Digital rejects a file we built, we find the error in the code and fix it. Free.

Since 28 June 2025, yes. The European Accessibility Act requires eBooks sold into the EU to meet EPUB Accessibility 1.1 and WCAG 2.1 AA. It applies regardless of where you are based. New titles must comply now; backlist titles already on sale have until 28 June 2030. Micro-enterprises are partly exempt. Accessibility enhancement — full metadata and an Ace by DAISY report — is available as an add-on with any ePub Conversion order.

Kindle or ePub conversion starts at $30. Print formatting starts at $40. Validation and repair starts at $20. Complex work — heavy illustration, multilingual, fixed layout — runs to around $125. Price depends on length, complexity, and how many formats you need. Bundles cost less than buying formats separately.

Yes. Repairs and rejection troubleshooting are a service line of their own. Send the file and the error message and we will tell you what is wrong before you pay.
