Troubleshoot file upload failures

Upload failures usually happen because of file type, size, or sign-in issues.

Steps to try

Confirm the file is TXT, PDF, or EPUB.
Try a smaller file to rule out size limits.
Refresh the page and re-upload.
Make sure you are signed in before uploading.

If uploads keep failing, you will need help. Reach out via the chat button in the bottom-right corner.
