Convertitore di ebook online

What Convertitore di ebook does

Ebook conversion changes how a book is packaged for a reading app or device. Convertitore di ebook 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 Convertitore di ebook

• 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.

Format comparison

Che cos'è il formato DOCX?

DOCX (Microsoft Word Open XML Document) è un formato di documento creato da Microsoft nel 2007. I file usano l'estensione .docx.

DOCX has been the default document format of Microsoft Word since Word 2007. It is a ZIP archive that contains XML files for the text, styles, images and settings, based on the Office Open XML standard published by Ecma and ISO. It replaced the older binary DOC format.

DOCX is the right choice for documents that other people need to edit, comment on or review with tracked changes, such as reports, letters, draft contracts, CVs and school work. Most offices expect this format.

The layout can change when a DOCX file is opened in a different program, in another version of Word or on a computer without the same fonts. For final documents that must look identical everywhere, PDF is a better choice.

Microsoft Word on Windows, macOS, iOS, Android and the web opens DOCX files, as do Google Docs, LibreOffice, Apple Pages and WPS Office. Web browsers cannot display DOCX files directly without an online service.

Che cos'è il formato PDF?

PDF (Portable Document Format) è un formato di documento creato da Adobe nel 1993. I file usano l'estensione .pdf.

PDF was created by Adobe to show documents the same way on any device and printer. A PDF file describes pages with text, fonts, vector graphics and images at fixed positions. It became an open ISO standard in 2008, and there are special variants such as PDF/A for archiving and PDF/X for printing.

PDF is the right choice for documents that must look the same everywhere, such as contracts, invoices, forms, manuals, reports and files for printing. It also supports digital signatures, fillable forms, comments and password protection.

PDF is hard to edit, because text is stored as positioned pieces, not as flowing paragraphs. Converting a PDF to Word may change the layout. Scanned PDFs contain pictures of text, not real text, unless OCR has been applied.

All major web browsers open PDF files directly. Windows, macOS, iOS and most Android phones include a PDF viewer, and Adobe Acrobat Reader and many free apps can view, annotate and fill PDF forms on all platforms.

Che cos'è il formato TXT?

TXT (Plain Text) è un formato di documento. I file usano l'estensione .txt.

A TXT file contains only plain text characters, without fonts, styles, images or layout. Today it is usually encoded as UTF-8, which can represent text in every language, but older files may use other encodings. Windows and Unix-like systems use different line endings, which can affect how a file looks.

TXT is the best choice for notes, logs, configuration, simple data exchange and any text that must open in every program for many years. It is also useful for removing formatting before you paste text elsewhere.

Plain text cannot store bold text, headings, tables, images or page layout. If a program detects the encoding incorrectly, accented letters and non-Latin scripts can appear as unreadable characters. Very old programs may not handle UTF-8.

Every operating system and device opens TXT files, including Windows Notepad, macOS TextEdit, Linux text editors, phones and web browsers. Every word processor and code editor can also open and save plain text.

Che cos'è il formato HTML?

HTML (HyperText Markup Language) è un formato di documento creato da Tim Berners-Lee (CERN) nel 1991. I file usano le estensioni .html o .htm.

HTML is the markup language of web pages. It was created by Tim Berners-Lee at CERN in the early 1990s, and today the WHATWG maintains it as the HTML Living Standard. Tags describe the structure of a document, such as headings, paragraphs, links, images and tables, while CSS controls its appearance.

HTML is the right choice for content that people will view in a web browser, such as web pages, help files, email newsletters and documents that should adapt to any screen size and contain links.

An HTML file often depends on separate images, style sheets and scripts, which are lost if only the single file is copied. Pages can look different in different browsers or email clients. HTML is not designed for fixed print layout.

Every web browser on every computer and phone opens HTML files. Word processors such as Microsoft Word and LibreOffice can open and save them, and any text or code editor can edit the source.

Perché usare Convertitore di ebook di FansBond

La maggior parte dei convertitori online carica i tuoi file sui propri server. Lo strumento Convertitore di ebook di FansBond, invece, fa tutto nel browser, grazie a WebAssembly e alle API moderne dei browser. I tuoi file restano sul tuo dispositivo, il che è più sicuro per foto private, contratti e lavori non ancora pubblicati, e spesso è anche più veloce perché non serve caricare né scaricare nulla.

Nessuna coda, nessuna filigrana e nessun account. Una volta caricata la pagina, lo strumento continua a funzionare anche con una connessione lenta.

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 Convertitore di ebook 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. Convertitore di ebook 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.
