Why do stray page numbers appear in the middle of the text?

Leftover running headers and footers, usually. A PDF repeats them on every page, and while conversion tries to strip anything recurring at page boundaries, imperfect detection lets the odd one slip through between paragraphs. A quick find-and-delete pass in an FB2 editor or Calibre cleans them up.

Is the FB2 really more readable than the PDF on an e-reader?

On a 6-inch e-ink screen, dramatically so — reflowed text at your chosen size and typeface versus squinting at a page formatted for A4 paper. That readability is the whole point of the conversion; the price is the original layout, so keep the PDF when exact appearance matters.

Can the FB2 inherit the PDF's table of contents?

Only when the PDF has a bookmark outline or clearly detectable headings — those become FB2 sections and power the reader's chapter navigation. A bookmark-free PDF converts into one long section, which you would need to split manually in an editor for proper chapter jumps.

PDF to FB2 conversion pulls the text out of fixed pages and rebuilds it as a reflowable FictionBook ebook suited to PocketBook and FBReader screens. Instead of panning around a shrunken page, you get text that adapts to the display with adjustable fonts and automatic hyphenation. Plain prose benefits most; layout-heavy documents should stay as PDF.

Why convert PDF to FB2?

Read a PDF novel comfortably on a 6-inch PocketBook instead of zooming and panning around a page designed for A4 paper.
Fold one-off PDF downloads into an FB2 library so every book gets the same fonts, hyphenation, and night mode.
Gain real e-reader behaviour — reflow, font scaling, dictionary lookup — that fixed PDF pages cannot offer on small screens.

Tip: Only PDFs with a selectable text layer can convert — scanned books need OCR first — and multi-column or heavily designed pages tend to lose their reading order. Single-column prose converts best.
