Frequently Asked Questions

Common questions about MD to HTML conversion

How does in-browser MD to HTML conversion protect my privacy?

Unlike legacy file converters that upload your confidential files to cloud servers, OpenFileConverter runs 100% locally on your computer or phone using Rust WebAssembly. Your original MD files never leave your device memory, guaranteeing zero retention.

What is the main difference between MD and HTML?

MD (Markdown Lightweight Markup) provides technical documentation, readme files, blog authoring, and github developer notes, while HTML (HyperText Markup Language) is optimized for web pages, online documentation, web applications, and hypermedia publishing. Converting allows you to balance file size, compression fidelity, and platform compatibility.

Does converting MD to HTML degrade visual quality?

No. OpenFileConverter uses high-fidelity chroma subsampling with configurable quality levels (default 92%), ensuring virtually indistinguishable image fidelity with sharp edges and rich colors.

Can I convert multiple files in batch?

Yes. You can drag and drop up to 100 files simultaneously. Because processing executes in parallel on your local CPU threads, batch jobs finish in seconds without queue wait times.
