Frequently asked questions about PDF form flattener

Can I edit the fields after flattening?

The generated PDF no longer keeps those controls as editable form fields.

Should I flatten before filling the form?

Usually no. Complete and verify the fields first, then flatten the finished copy.

Does flattening add a digital signature?

No. It fixes form fields into page content; it does not create a digital signature.

Does the tool change my original file?

The tool creates a new result; the PDF you selected remains unchanged.

Can I use it with a password-protected PDF?

A protected PDF may need to be unlocked before the tool can read or process it.

Will large files take longer?

They can. Processing time depends on the file size, page count, and the work required for each page.
