Flatten PDF Form Fields

Flattening converts interactive form fields into static content embedded in the PDF. Text fields, checkboxes, radio buttons, and dropdowns are all converted to permanent, non-editable elements.

Why Flatten?

  • Prevent editing — Ensure filled values cannot be changed after submission.
  • Compatibility — Some viewers display blank fields; flattening fixes this.
  • Reduce size — Removing form metadata can reduce file size.
  • Printing — Flattened PDFs print more reliably.

How It Works

  1. Upload your PDF form.
  2. Review detected form fields.
  3. Flatten — Click to convert all fields to static content.
  4. Download the flattened PDF.
