What does flattening a PDF form mean?
Flattening a form converts interactive fields (text inputs, checkboxes, dropdowns, signatures) into static content within the PDF. The values that were entered are visually preserved, but can no longer be edited or modified.
Is form data lost when flattening?
No. All values entered in the fields are preserved as-is in the resulting PDF. The difference is that they go from being editable fields to fixed content integrated into the page.
Is it safe to flatten forms with sensitive data here?
Yes. All processing happens in your browser. Your files are never uploaded to any server. The form data stays on your device at all times.
Does it work with all PDF field types?
Yes. PDFSuite supports all standard PDF form field types: text fields, checkboxes, radio buttons, dropdowns, and signature fields.
Do I need to create an account to use this tool?
No. PDFSuite works without registration, without an account, and with no usage limits. Simply load your PDF and flatten the form.
