Frequently Asked Questions
What types of PDF form fields are supported?
This tool supports all common interactive PDF form field types including text fields, checkboxes, dropdown menus, and radio button groups. These are standard AcroForm fields used in most fillable PDF documents.
What does "flatten" a PDF form mean?
Flattening a PDF form converts the interactive form fields into static content. After flattening, the filled values become part of the page and can no longer be edited. This is useful when you want to share a completed form and prevent further changes.
Is my PDF data secure?
Yes, completely. All processing happens entirely in your browser using client-side JavaScript. Your PDF files are never uploaded to any server. The data stays on your device throughout the entire process.
Why does my PDF show no form fields?
If no fields are detected, your PDF likely does not contain interactive AcroForm fields. Some PDFs that appear to have forms are actually just static layouts without actual form field objects. You may need to use a PDF editor to add interactive form fields before using this tool.
