AZ Tooling

Local API · free & private

Your browser tab is the API server

Every other converter sells API access to their servers. AZ Tooling flips it around: an open browser tab is the server. Generate a key, keep the tab open, and drive bulk jobs from your scripts. Files are processed on your machine, never uploaded.

How it works

  1. 01
    Generate your key

    Create a local API key above. It's stored only in this browser, never transmitted.

  2. 02
    Connect a client

    Run npx aztooling-bridge --key <key> with your API key. It listens on ws://127.0.0.1:8787 and exposes a plain HTTP endpoint for your scripts.

  3. 03
    Submit jobs

    Send a tool slug, files, and options; watch progress; download results.

What you can drive: convert (430+), compress, background removal, OCR, and captions. Full reference (SDK methods, HTTP endpoints, protocol messages, and the security model) lives in the Documentation tab.
