Pretvorite EPUB u MOBI

What EPUB u MOBI does

Ebook conversion changes how a book is packaged for a reading app or device. EPUB u MOBI reads the chapters, headings, paragraphs, lists, tables and images of the source file (from a PDF, only the text) and writes them into a new format.

EPUB output is an EPUB 3 book with a table of contents built from the headings. MOBI output uses the older Mobipocket format that Kindle devices can open. PDF output lays the text out on fixed pages with embedded fonts. The original styles and fonts of the book are not copied.

When to use EPUB u MOBI

• Convert a DRM-free EPUB from an independent store to MOBI for an older Kindle that cannot open EPUB.
• Turn a PDF manual or report into EPUB so the text reflows and stays readable on a small phone or e-reader screen.
• Make a printable PDF from an EPUB to read on a laptop or print a few chapters on paper.
• Save a long web article as an HTML file, then convert it to EPUB to read it offline on an e-reader.

Settings explained

Output format

Chooses the type of book to create. EPUB works with Apple Books, Google Play Books, Kobo and most e-readers. MOBI is for older Kindle devices. PDF keeps fixed pages, and TXT keeps only the text.

Page size

Shown when saving as PDF. A5 is close to a paperback page and comfortable on tablets. A4 and Letter suit printing on standard office paper.

Orientation

Shown when saving as PDF. Portrait is the normal choice for books. Landscape gives long lines, which are harder to read, but it can help with wide tables.

Document title (optional)

Sets the book title that reading apps show in the library. Leave it empty to keep the title stored in the source file, or else the file name.

What changes when you convert EPUB to MOBI

Format comparison

Što je EPUB?

EPUB (Electronic Publication) je format za e-knjige predstavljen 2007. godine (razvio: IDPF). Datoteke imaju nastavak .epub.

EPUB is an open e-book standard first published by the International Digital Publishing Forum and now maintained by the W3C. An EPUB file is a ZIP archive with XHTML content, CSS styles, images and metadata. The text is usually reflowable, so it adapts to the screen size and the reader's font settings.

EPUB is the right choice for books, long articles and documents that people will read on e-readers, tablets and phones, where reflowable text and adjustable font sizes are more comfortable than fixed PDF pages.

Complex layouts, such as magazines or comics, do not always display well. Many purchased EPUB books use digital rights management, which prevents conversion. Reading apps differ in how well they support EPUB 3 features.

Apple Books, Google Play Books, Kobo devices and Calibre open EPUB files. Kindle devices and apps accept EPUB through Send to Kindle, which converts the file. On Windows and Android, a separate reading app is usually needed.

Što je MOBI?

MOBI (Mobipocket eBook) je format za e-knjige predstavljen 2000. godine (razvio: Mobipocket). Datoteke imaju nastavak .mobi ili .prc.

MOBI is the Mobipocket e-book format, based on the older PalmDOC format. Amazon bought Mobipocket in 2005 and used MOBI as the basis of early Kindle formats such as AZW. It stores simple HTML-based content with limited styling compared with EPUB or later Kindle formats.

MOBI is now useful mainly for older Kindle e-readers and for opening existing e-book collections. For new e-books, EPUB is the better choice, and current Kindle devices receive books in newer Amazon formats.

MOBI is deprecated. Amazon no longer accepts MOBI files through Send to Kindle or for new Kindle publishing, and the format supports only basic formatting. Purchased books may use digital rights management that prevents conversion.

Older Kindle devices and the Calibre e-book manager open MOBI files. Some third-party reading apps on Android, iOS, Windows and macOS also read them. Web browsers, Apple Books and Google Play Books do not support MOBI.

Tips for the best result

• Use the title field when the source has an unclear title, such as a file name like scan_0042. E-readers sort and search the library by this title.
• From a PDF, each page usually starts a new section in the table of contents, and paragraphs that cross a page break are split in two.
• Scanned PDFs contain no text. They are converted as page images, which do not reflow on a small screen, so EPUB gives little benefit.
• Check the table of contents after converting. Chapters are split at the main headings, so a book without real headings gets long or numbered sections.

How EPUB u MOBI works in your browser

Documents are first read into a common structure of headings, paragraphs, lists, tables and images. DOCX files are read with mammoth, PDFs with pdf.js text extraction, and EPUB files are unpacked in the browser.

The structure is then written in the target format: DOCX with the docx library, PDF with pdf-lib and embedded Unicode fonts, EPUB and MOBI as standard ebook packages. The content is kept, but the exact page layout of the original is rebuilt rather than copied.

Privacy and security

Most online converters upload your files to a server, process them there and keep a copy for some time. EPUB u MOBI works differently: the code is downloaded to your browser once, and your files are read and written only on your device.

You can check this yourself: after the page has loaded, turn off your internet connection and the tool still works. This makes it safe for contracts, IDs, medical records, private photos and unreleased work.
