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.

Converting other files for an AI chat or notes app? File to Markdown takes PDF, Word, PowerPoint, Excel and more in one place.

What you get

Every slide, in order

AI tools often read a slide deck out of order or skip notes and charts. Markdown puts each slide under its own heading, so nothing is missed.

  • One section per slide

    Each slide starts with a comment giving its slide number, then its title as a heading.

  • Tables and chart data

    Tables become Markdown tables, and charts come out as a table of their data.

  • Speaker notes

    Notes are kept under each slide, often the most useful part for an AI summary.

  • Text only

    Pictures and slide design aren't kept. Older .ppt files work too.

  • Private: no AI service sees the file

    The conversion runs on our own servers with open-source software. Your file is never sent to an AI provider, and it's deleted after conversion.

What is a PPTX file?

PowerPoint Open XML Presentation

Developed By
Microsoft
Initial Release
2007
MIME Type
application/vnd.openxmlformats-officedocument.presentationml.presentation

The PPTX format is the default XML-based presentation file type for Microsoft PowerPoint 2007 and later, standardized as ECMA-376 and ISO/IEC 29500 (Office Open XML). It replaces the binary PPT format by using a ZIP-compressed directory structure containing separate XML files for slide data, themes, and metadata, alongside folders for embedded media. This modular architecture reduces file size via deflate compression and improves data recovery, as undamaged components remain accessible even if specific XML parts are corrupted.

How to open a PPTX file

PPTX is natively supported by all Microsoft PowerPoint versions from 2007 onwards on Windows, macOS, iOS, and Android. It has broad cross-platform support, with full editing capabilities available in Apple Keynote, Google Slides, and LibreOffice Impress. Because it is a ZIP archive, users can also rename the extension to .zip to manually extract embedded media assets without specialized software.

What is an MD file?

Markdown Documentation

Developed By
John Gruber
Initial Release
2004
MIME Type
text/markdown

An MD file is a plain text document containing Markdown, a lightweight markup language created by John Gruber and Aaron Swartz. The format uses non-alphabetic characters (such as hashes for headers and asterisks for emphasis) to define formatting syntax that is human-readable in its raw form and easily convertible to valid XHTML or HTML. It is the de facto standard for documentation in version control systems like Git.

How to open an MD file

As strictly plain text, MD files can be opened and edited in any basic text editor such as Microsoft Notepad or Apple TextEdit. For a rendered preview of the formatting, specialized editors like Obsidian, Typora, or Visual Studio Code are recommended.
