Flattening converts interactive form fields — text boxes, checkboxes, dropdowns — into ordinary page content. The filled-in values stay visible exactly as they appear, but the fields themselves are removed, so nobody can click in and change an answer afterwards.
generalFlatten right before you send a completed form: job applications, signed agreements, tax or insurance paperwork. It prevents accidental edits, avoids viewers that render form fields inconsistently, and makes the document print exactly as it looks on screen.
usageThe tool tells you no form fields were found and returns an unchanged copy of your document instead of failing. That makes it safe to run on mixed batches where only some files contain forms.
usageNo. Field appearances are regenerated from their current values before merging, so the flattened page shows the same text, checks and choices in the same place. Only the interactivity is removed.
technicalNo. Flattening removes form interactivity but anyone can still view the file normally. If you need to restrict opening or editing with a password, use a PDF password tool — the two protections combine well for sensitive forms.
