Os campos de formulário são fixados nas páginas. Um PDF sem formulário é simplesmente guardado de novo.
To flatten a PDF is to merge its interactive fields — text boxes, checkboxes, buttons — directly into the page content. Their appearance is preserved exactly, but they stop existing as editable elements: what was a ticked checkbox becomes a plain drawing on the page rather than an object that can be unticked.
Why flatten a PDF form? Because a completed form remains, by default, editable by whoever receives it. By flattening it before sending, you get a non-editable document that permanently locks the answers entered and prevents any later change. It also guarantees consistent display: the file will look the same across every viewer, whatever software, version or system is used to open it.
If your file contains no interactive fields, flattening does not degrade anything: the document is simply re-saved cleanly, with no loss of quality or content. The operation is therefore always safe to run.
To go further, consider the companion tools: repair if the file has a damaged structure, compress to reduce its size once flattened, and web-optimize to prepare it for fast online viewing.
On privacy, no sign-up is required and your files are deleted automatically after processing. Your documents are used only to produce your flattened PDF, nothing more.

Flattening a PDF merges interactive form fields (text, checkboxes, buttons) into the page content: their appearance is preserved but they can no longer be edited.
No problem: if the PDF contains no form fields, the tool simply re-saves it cleanly without altering its content.

No, flattening is irreversible and permanently locks the field content. Keep a copy of the original file if you may still need to complete or correct it.
