Yes. OpenOnPhone can show a quick local view for .db files in your browser.

What is a .db file?

DB is a generic database extension. OpenOnPhone previews it only when the file header is valid SQLite.

Why is .db hard to open on a phone?

  • Phone file viewers usually cannot show database structure.
  • Opening a database with the wrong app may expose data or fail silently.
  • A schema-only preview is enough to confirm tables without reading row data.

What OpenOnPhone does not do

OpenOnPhone is for quick local inspection. It does not replace the original professional app for editing, conversion, exact layout, formulas, measurements, security review, or full workflow features.

MIME examples

  • application/vnd.sqlite3
  • application/x-sqlite3
  • application/octet-stream

Next steps
