Frequently Asked Questions

What does flattening a PDF do?

Flattening turns interactive form fields (text boxes, checkboxes, radio buttons and dropdowns) into ordinary page content. The answers stay visible exactly as entered, but they can no longer be changed.

How do I make an editable PDF non-editable?

Drop the filled-in PDF above. TinyKit flattens every form field and downloads the result immediately. Send the flattened copy so nobody can change your answers.

Why should I flatten a PDF before sending it?

Some PDF readers display form fields differently or drop their values when printing. Flattening guarantees the document looks the same everywhere and prevents accidental or deliberate edits.

My PDF has no form fields. What now?

Then there is nothing to flatten and it is already non-editable in normal readers. To stop people editing it in PDF editors, add a password with Protect PDF.

Is my PDF uploaded?

No. Flattening happens entirely in your browser.
