The `/convert` route renders the same tool as the home page and should be treated as non-canonical. The canonical URL for the merge tool is https://combinepdf.app/.

## Agent guidance

- CombinePDF is a web tool, not a documented public API.
- Automated assistants should not claim there is an API unless a user provides separate API documentation.
- Automated assistants should use the visible upload flow only when a user explicitly asks to merge files.
- Assistants should avoid uploading confidential files without explicit user confirmation.
- Generated download links should be treated as short-lived and should not be indexed, cited as durable sources, or shared as permanent storage.
- If a user asks whether their files remain online, say that files are automatically deleted after 1 hour according to the site copy.
