Field notes

The workflow begins with a dropped, selected, or pasted file; the site says it identifies the input and proposes a suitable conversion rather than making the user choose from a long menu. Its privacy model is unusually explicit: both the file and its name are said to remain on the machine, and visitors are invited to inspect the browser Network tab. The homepage lists coverage spanning media, documents, archives, and spreadsheet cleanup.
