How are the book's footnotes handled?

They land in one of FB2's best features: dedicated note bodies that PocketBook and FBReader display as tap-to-open notes rather than page jumps. Annotated translations read particularly well this way.

Is FB2 a good home for Russian-language Kindle books?

Arguably the best one — FB2 readers hyphenate automatically, which matters for long Cyrillic words on narrow e-ink screens, and the format's genre and sequence metadata matches how Russian-language libraries are organised. The text itself converts unchanged; the win is the ecosystem around it.

Why did the file get bigger after converting?

FictionBook embeds images as base64 text inside uncompressed XML, which inflates them by roughly a third. Libraries commonly store the format zipped as .fb2.zip for exactly this reason — and most FB2 readers open the zipped file directly, no extraction needed.

Turning an AZW3 ebook into FB2 moves a Kindle-locked book into FictionBook, the open XML format PocketBook readers and Russian-language libraries favour. Where AZW3 ties a title to Kindle software, FB2 is vendor-neutral and fiction-focused. The switch pays off whenever your reading runs through FBReader, CoolReader, or an OPDS catalogue rather than Amazon's apps.

Why convert AZW3 to FB2?

Read Kindle-format books on PocketBook and Onyx e-readers, which render FB2 natively but cannot open AZW3 at all.
Slot titles into FBReader, CoolReader, or an OPDS catalogue where FictionBook's genre and sequence metadata does the shelving.
Hold an open-format copy of books that would otherwise exist only inside Amazon's proprietary container.

Tip: Expect typography to reset — embedded fonts and custom CSS from the AZW3 have no FictionBook equivalent, so your reader's defaults take over while structure, images, and notes survive.
