What does flattening a PDF do?

Flattening turns interactive AcroForm fields into regular page content, so the values can be viewed but not edited as form controls.

Does flattening redact hidden content?

No. Flattening only removes editable form controls. Use a dedicated redaction tool for sensitive content that must be removed.

No. The PDF is processed locally in your browser and is never sent to a server.
