We prefer source files created using Word (.doc, .docx) and InDesign (.indd). These file types produce the best looking eBooks. Third-party software programs that export .doc files may not be of the same quality as Word. For best export results, consult the manual for the publisher program being used.
We also accept Text file (.txt), HTML (.html), Pages (.pages), Quark (.qxd) and PDF (.pdf). These conversions may take longer and will require careful proofing by the author. Other file formats may be accepted. Please contact us to confirm.
You may also upload an ePub file. Before uploading your ePub file, validate it here: http://validator.idpf.org/.
Our uploader has a maximum file-size limit of 100MB. If your book is larger than that please contact us at firstname.lastname@example.org.
