Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert your complex HTML documents into clean Markdown files instantly. This tool is perfect for developers, technical writers, and content creators who need to migrate web content into lightweight documentation systems.
HTML is a feature-rich, tag-based markup language designed for rendering web pages, while Markdown (MD) is a minimalist, plain-text format focused on readability and ease of authoring. During this conversion, our engine strips away complex HTML tags (like <div>, <span>, or <script>) and maps structural elements like headings, lists, and links into their native Markdown syntax. The result is a clean, human-readable file that maintains the logical hierarchy of your original data.
Since both HTML and MD are text-based formats, the conversion process is lossless. All your textual content and structural formatting are preserved with 100% fidelity.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
