The problem
Your book is in the wrong format. Again.
An EPUB your Kindle won't take, a PDF that's unreadable on a 6-inch screen, a comic in a format nothing opens. The usual fixes come with catches.
Upload your library to convert it
Online converters want every book on their servers, one file at a time, with size limits and a queue.
Ads around every download
Free converter sites wrap the result in pop-ups and look-alike download buttons.
A cockpit of settings
The powerful desktop tools expect you to know which output profile and options suit your reader.
PDFs that won't reflow
Converted PDFs keep running headers, page numbers and lines broken in the middle of sentences.
Kindle e-mails that bounce
Send to Kindle rejects a book with a bare error code and no idea what to fix.
Downloads you can't trust
Free "eBook converters" that come bundled with toolbars, adware and installers that change your browser.
Vow eBook Converter fixes all of it.

Get a DRM-free book onto your Kindle in a couple of minutes.
Step 1: get it freeDownload and install it free
Get Vow eBook Converter from this page and run the installer. It needs no administrator rights and no account, and adds itself to Open with for eBook files without taking over any default app.
Drop the EPUB on the window
Drag the book onto the app, press Ctrl+O, or paste it with Ctrl+V. The format is recognised from the file's content, not just its extension.
Choose your Kindle under My reader
Pick your model, for example Kindle Paperwhite. MOBI is chosen for copying over USB, pictures are sized for its screen, and the choice is remembered.
Press Convert
Press Convert or Ctrl+Enter. The book is saved to Documents\Vow eBook Converter as "Author - Title", and existing files are never overwritten.

FAQ
Questions about eBook Converter
Is Vow eBook Converter free?
Yes. You can convert 5 books a day for free, one at a time, in every format, with the device presets, metadata editing and live preview, and converting the same book again that day is free. There are no ads and no watermarks. Unlimited, a one-time $4.95 USD payment, adds any number of books, batch conversion of lists and folders, Send to Kindle and USB copies, and cover and layout editing.
Can it remove DRM?
No. Books locked with Adobe, Apple, Kindle or other DRM are recognised and the app explains why they can't be converted, but DRM is never removed. It converts DRM-free books, such as public-domain classics, indie purchases and your own writing.
Are my books uploaded?
No. Converting happens entirely on your own PC. The app only goes online when you press Find details online (the title and author are looked up on Open Library) or when you send a book to your Kindle by e-mail.
Which formats does it read and write?
It reads EPUB, KEPUB, MOBI, AZW3, PDF, DOCX, ODT, FB2, HTML, TXT, Markdown, RTF and CBZ, CBR and CB7 comics. It writes EPUB 3 and 2, KEPUB, MOBI for every Kindle, PDF, DOCX, ODT, FB2, HTML, TXT, Markdown, RTF and CBZ. AZW3 is read but not written, and Amazon's KFX format isn't read.
How do I get an EPUB onto my Kindle?
Pick your Kindle under My reader and press Convert, then drag the file onto the Kindle in File Explorer. With Unlimited you can copy it from the Send page, or set up Send to Kindle once: the app walks you through Amazon's approved-sender step and e-mails books as EPUB, Amazon's preferred format.
How good is PDF to EPUB?
It does far more than copy the text out: columns and reading order are worked out, paragraphs are rebuilt across page breaks, running headers and page numbers are removed, and PDF bookmarks become chapters. Results still depend on the PDF; complex tables and maths come out as plain paragraphs, and scanned PDFs keep their page pictures.
Does it handle comics and manga?
Yes. CBZ, CBR and CB7 comics and comic PDFs are converted with pictures sized for your screen and greyed for e-ink. Double-page spreads can be split, and right-to-left manga order is supported, switched on automatically when the comic says so.
Is it safe to install?
Yes. It is made and published by XTO Pty Ltd, an Australian company. There are no ads, no bundled software and no account, it needs no administrator rights, it never changes your default apps, and it uninstalls cleanly from Windows Settings.
