Frequently Asked Questions
What does flattening a PDF do?
Flattening merges interactive elements like form fields, annotations, and comments into the static page content. The visual appearance is preserved, but the elements can no longer be edited.
Is text still searchable after flattening?
Yes. Flattening preserves the underlying text layer, so all text remains fully searchable and selectable.
Is my file uploaded to a server?
No. All processing happens entirely in your browser. Your PDF never leaves your device.
What happens to filled form data?
Filled form data is preserved as static text. The values you entered remain visible but can no longer be edited.
