Questions
Why does my reader still show the old title? ＋
Most apps cache metadata when a book is first imported. Remove the book from your library and re-add the new file.
Does this re-encode my book? ＋
No. Only the metadata block in the package file is edited; every other byte is preserved.
Can I change the cover here? ＋
Use the Cover Editor for that — it is a separate tool.
Are my files private? ＋
This tool runs entirely inside your browser — your file is never uploaded anywhere. It stays on your device, and closing the tab is all it takes to remove it.
Is it really free? ＋
Yes. Every tool, every file size, no account. There is no paid tier and nothing is held back.
