How to get started
- Click "Use online" above — it runs in your browser, no signup required.
- Run the full workflow (open → edit → export) on a throwaway file first, to confirm format compatibility.
- Once you accept its limits, migrate your daily workflow; keep the original software as a fallback for critical deliverables.
