Why “no upload” matters
Every conventional converter site works the same way: your file travels to their server, sits in their queue, gets converted on their hardware, and – you hope – gets deleted afterwards. You can’t verify any of it. The FBI has even warned about free converter sites that use that upload as a way to deliver malware or harvest the documents themselves. Your books are yours; a format change shouldn’t require handing them to a stranger.
ebook.tools removes the question entirely. The converter is delivered to your browser as code and runs on your machine; the file you drop is opened from memory, transformed, and saved back – the network isn’t involved at all. That isn’t a policy promise, it’s an architecture, and you can test it: load this page, switch off your wifi, and convert. It works exactly the same, because there was never anything to send.
A private FictionBook reader that opens FB2 on any device
FB2, or FictionBook, is a tidy XML ebook format that is popular across Russia and much of Eastern Europe, and beloved by archivists because the whole book, including its images, lives in one clean, semantic file. The catch is that few mainstream apps open it, so reading an .fb2 on a phone or a work laptop usually means installing something. This reader opens it right in the browser, entirely on your own machine, so the file is never uploaded anywhere.
Opening a book here parses the FictionBook XML, pulls out its sections, images and table of contents, and shows one chapter at a time with a contents list you can move around in. Text resizes to whatever is comfortable, the layout reflows to your screen, and it respects your system’s light or dark theme. Zipped .fb2.zip files are unpacked in place, so you do not have to extract them first.
Because the reader runs locally, there is a genuine security benefit too. An ebook can carry markup that tries to load remote images or run scripts, which is how a file quietly reports that it was opened. Each chapter renders inside a locked-down sandbox with scripting disabled and no network access at all: pictures and styling from inside the book are inlined so it displays correctly, while anything pointing at the internet is stripped away.
Cyrillic and other non-Latin text render correctly, including older files saved in Windows-1251, whose encoding is read straight from the XML declaration. If you would rather keep a copy that opens in more places, the FB2 to EPUB converter produces a clean EPUB on your device, ready for our EPUB reader or any other app.
