How it works

Three steps to your converted file

Everything happens in your browser tab - upload, pick a format, download. The heavy lifting runs on our servers.

  1. 01

    Upload your file

    Drag and drop, click to browse, or paste a URL. Batches take up to 20 files at once - 230+ input formats across video, audio, image, document, and archive types.

  2. 02

    Choose an output format

    Pick from over a hundred output formats. Filter by category or search by name - every option is open to everyone, no account needed.

  3. 03

    Convert & download

    Hit Convert and grab your download link moments later. Originals are erased when the job completes; results are cleared within about an hour.

What is an XML file?

Extensible Markup Language

Developed By
World Wide Web Consortium (W3C)
Initial Release
1998
MIME Type
text/xml

XML (Extensible Markup Language) is a flexible text format derived from SGML (ISO 8879) and defined by the W3C (World Wide Web Consortium) Recommendation. It utilizes a self-descriptive tree structure of nested tags and attributes to store and transport data, independent of hardware or software platforms. Unlike HTML, XML does not use predefined tags; it relies on custom schemas (XSD) or DTDs to define the document structure.

How to open an XML file

Since XML is encoded in plain text (usually UTF-8), it can be opened and edited with any text editor such as Notepad++, Sublime Text, or Visual Studio Code. Web browsers like Chrome and Firefox natively render the file as a collapsible Document Object Model (DOM) tree for viewing structure.

What is an EPUB file?

Electronic Publication

Developed By
IDPF / W3C
Initial Release
2007
MIME Type
application/epub+zip

EPUB (Electronic Publication) is an open e-book standard maintained by the World Wide Web Consortium (W3C), originally developed by the International Digital Publishing Forum (IDPF). It utilizes the Open Container Format (OCF) based on ZIP compression to package XHTML content, CSS styling, and XML metadata. EPUB supports reflowable content, allowing text to adapt to various screen sizes, and fixed-layout rendering for graphic-heavy publications. The current version, EPUB 3.2, supports HTML5, SVG, and JavaScript interactivity.

How to open an EPUB file

EPUB files require dedicated e-reader software as most operating systems do not natively render them. On desktop environments (Windows/macOS/Linux), Calibre is the industry-standard management tool, while Adobe Digital Editions handles DRM-protected files. For mobile devices, Apple Books (iOS) and Google Play Books (Android) provide native rendering. Browser-based extensions like EPUBReader for Chrome allow viewing without standalone software.
