Tools

All files are deleted within 24 hours at most.

Word to EPUB converter: the manuscript is converted in your browser. It is not uploaded to any server and not kept.

ONIX validator: the file is checked in your browser. It is not uploaded to any server and not kept.

EPUB validator: the file is uploaded to our servers in the European Union, validated, and deleted as soon as validation finishes. The report is kept for 24 hours at most so you can come back to it or share its link; then it is deleted. The automatic repair happens in your browser; if you ask to validate the repaired file, it is uploaded and deleted just like the original.

Use and abuse: to prevent abuse, use of the tools is monitored. If you do not agree, do not use them.

Image descriptions: what you write in the image review is kept only in your browser. After 24 hours it is no longer used, and it is deleted the next time you open the EPUB validator.
