What the ebook converter covers
A book you own should open on the device in your hand. This tool moves it between reader formats and rebuilds the structure — chapters, navigation, cover — instead of dumping raw text.
- Take an EPUB to AZW3 or MOBI so a Kindle will display it properly
- Go the other way and move a MOBI or AZW3 onto Kobo, Tolino or a reading app
- Turn a PDF into EPUB when fixed pages are unreadable on a small screen
- Convert CBZ and CBR comic archives into EPUB or PDF for ordinary readers
- Rescue LIT, PDB and LRF files from devices that no longer switch on
- Migrate a whole shelf in one batch when you change e-reader brands

Worth knowing
Eleven reader formats
EPUB, MOBI, AZW3, FB2, PDF, LRF, HTMLZ and PDB both ways, with CBZ, CBR and LIT read in as sources.
Built for the device
AZW3 and MOBI for Kindle hardware, EPUB for everything else. Pick the target and the file is packaged the way that reader expects.
Structure kept
Chapter breaks, navigation, cover art, title and author survive the move, so your library does not turn into a list of Unknown.
Comics handled
CBZ and CBR archives unpack in page order and come out as EPUB or PDF a normal reading app will open.
Dead formats revived
LIT, PDB and LRF files from readers that stopped shipping a decade ago convert into EPUB you can actually use.
Shelf-sized batches
Queue a folder of books at once when you switch ecosystems, and collect the converted set in a single download.

Questions
Which formats can I convert?
EPUB, MOBI, AZW3, FB2, PDF, LRF, HTMLZ and PDB work as source and target. CBZ, CBR and LIT are read-only inputs — send them in, convert them to something current.
Does the table of contents survive?
Yes. Chapter breaks, the navigation list, cover image, title and author are carried into the new file, so your library stays sorted.
Which format should I pick for a Kindle?
AZW3 on anything modern, MOBI on older hardware. For Kobo, Tolino, PocketBook and phone apps, EPUB is the safe answer.
Can it open a protected book?
No. Files carrying DRM from a store cannot be converted here, and we make no attempt to strip it. Convert books you own outright or that are published unprotected.
How large a file is accepted?
50 MB per book, which covers illustrated non-fiction and most comic archives. Very large scanned collections should be split first.
What do plans change?
A plan puts your conversions on dedicated workers and raises the maximum file size. Without one you convert on the shared queue under a daily cap.
