Visit KoboRespect the format and the creator
A highly designed workbook may be intentionally delivered as PDF because placement matters. A conventional prose book may simply use PDF because it was easy for the creator to export. Convert when it improves personal reading, not to strip protections or redistribute the work.
Preserve purchase receipts and originals. Metadata such as title and author may need manual cleanup after generic conversion.
Build a library you will return to
Use consistent filenames and metadata, choose one primary reader, and avoid scattering the same book across many services. If an ebook is reference material, a highlight workflow can be more useful than format conversion alone.
