Upload your EPUB.
EPUB Preflight audits the EPUB and notifies you by email when the audit is completed.
When you sign up, you receive 1 GB of free preflight upload credit. That is enough credit to upload 500 average-sized EPUBs (2 MB each on average).
When you’re ready to do more, you can purchase additional credit. We don’t charge a subscription, your upload credit never expires, and your uploads are never deleted unless you tell us to.
