FAQ

Text and Dev Tools questions

Are these tools free?

The current browser-based workflows are free to start. Paid features later should focus on higher limits and power-user workflows.

Do files leave my browser?

Most current tools are browser-local. If a future tool needs server processing, the page should disclose it before upload.

Where should ads go?

Ads should sit below the main workflow, after results, or before FAQ content. They should not interrupt upload, settings, or download actions.
