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.

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.

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.

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?

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 a MOBI file?

The Mobipocket eBook format (MOBI) is a binary distribution format developed by Mobipocket SA in 2000, utilizing the Open eBook (OEB) standard and XHTML for reflowable content layout. Encapsulated within a Palm Database (PDB) container, MOBI files employ either the LZ77-based PalmDOC compression or the proprietary HUFF/CDIC algorithm to minimize file size. The format supports Digital Rights Management (DRM), metadata indexing, and javascript capabilities, serving as the foundational architecture for Amazon's proprietary AZW format before the adoption of KF8.

How to open a MOBI file

Native support for MOBI is restricted primarily to Amazon Kindle hardware and legacy Mobipocket readers. On Windows, macOS, and Linux, users require third-party eBook management software such as Calibre, which offers comprehensive viewing and conversion capabilities. Alternatively, the Kindle Previewer tool provided by Amazon or multi-format readers like FBReader and Sumatra PDF can render the unencrypted content of these archives.
