Get Started

If you're new to Glassboxx and have a single eBook or audiobook to sell and distribute with all the benefits Glassboxx offers, simply fill in the details and upload your asset files below.

For the asset files, you need:-

a cover image as a jpg/jpeg file, named as <ISBN13>.jpg and with a width of 800px. Audiobook cover images should be square and eBook images should be in 3:4 ratio, and be 72 ppi and web optimised.

and for an audiobook, mp3 files named as <ISBN13>_nnn_MP3.mp3 where nnn is a 3 digit sequence number for the file within the audiobook. For example, for a book with ISBN 9781407951058, the track 1 file must be named 9781407951058_001_MP3.mp3 and the track 2 file must be named 9781407951058_002_MP3.mp3 etc.

or for an eBook, an ePub file named as <ISBN13>.epub, and it is not necessary to include a cover image in it.

Finally, ensure the mp3 and ePub files you upload here must not be bigger that 200MB each, and the overall size of the book must not exceed 800MB. (If your book is larger than this, contact us to find out about other options for you to send us your books.)
