Local document conversion, end to end

UnpackMD uses a browser worker and WebAssembly to process document bytes without a file-processing backend.

How it works

1. Add local files

Choose files, a supported folder or a mixed collection. Conservative size and file-count limits protect browser memory.

2. Convert locally

A browser worker processes supported documents on your device, keeping the interface responsive without sending document contents to a conversion server.

3. Inspect real results

Review Markdown, a safe rendered preview, extracted assets and structure counts available from the document model.

4. Export locally

Build Markdown archives, context packs, project ZIPs or heading-aware JSONL directly in the browser.
