Content Conversion Guidelines
Revised September 2015
As a result, we ask that you do not insert page numbers into your document. These will be
ignored during the conversion process, and could potentially cause conversion errors.
If you have made your own ePub file, or have generated one through a different conversion
service, make sure that you run the file through an ePub validator before uploading it to your
Kobo Writing Life account. Note that there are many free ePub validators online.
ePub files will fail to upload to your Kobo Writing Life account if the file size is too large or if
there are errors within the file.
If errors are flagged when you run your file through an ePub validator, be sure the correct those
errors and run the ePub through the validator again before uploading the file to your account.
Files with errors in them may display properly on our devices and in our applications, but in
order to guarantee that your readers can view the file on any device, we do not allow for files
with any formatting issues. You will therefore receive an error message at file upload if your file
contains any errors.
When loading a new book to your Kobo Writing Life account, at the “Add e ook ontent” step,
we have made available a “What-You-See-Is-What-You-Get”, or “WYSIWYG” tool.
If you have a few small changes that you would like to make to the content that you uploaded,
the WYSIWYG tool makes it simple to make these edits. Note, however, that if possible, it is
always recommended that you perfect the file itself and upload a well-formatted and edited file
to your account.
At any time before or after publishing your book to our site, you can make changes to the
content of your book in one of two ways:
uploading a newly edited file
editing the content using our WYSIWYG tool
