What does flattening actually do?

It writes each page out as one picture. The lines, fields and layers stop being separate objects.

Does the text stay selectable?

No. A flattened page is a picture, so the words cannot be copied or searched.

To stop a form or an invoice from being edited, or to make a layout hold together on every reader.

Flatten a PDF, so each page becomes one flat picture that nobody can edit by accident.

Drag & drop a PDF, or choose it from your device. It stays on your machine.
