How JAR to Markdown works

  1. JAR
  2. archive listing
  3. members · nested converters
  4. GitHub-Flavored Markdown

Built for JavaScript runtimes

Node.js

Read local files, uploads, S3/R2 objects, and other byte sources.

Cloudflare Workers

Open ZIP archives directly inside Workers without unzip or a native binary.

Browser

Inspect JAR files locally without uploading them to a server.

Edge

Run the same TypeScript converter in compatible Edge runtimes.

What @mdgate/zip extracts

  • Member names as Markdown when used alone
  • Each member handed back to the same converter registry inside create()
  • Nested archives and attachments converted by the matching format package
  • Encrypted member detection

Why @mdgate/zip

Runs where your JavaScript runs

No separate processing service. The converter is TypeScript you can call from Node.js, Cloudflare Workers, Edge runtimes, and browsers.

Local conversion

JAR files can stay inside your application or browser.

Content detection

Recognizes JAR files from their contents, not only the filename.

Deterministic parsing

The same JAR file produces repeatable Markdown without model inference.

Small runtime surface

No Python. No native addons. No WASM. No third-party runtime dependencies.

JAR for AI agents

Turn JAR files into content your agent can actually work with.
