Frequently Asked Questions
What does flatten mean?+
The form fields are merged into the page as normal text and marks. They look the same but can no longer be clicked or changed.
Can I undo flattening?+
No. Keep the original editable file if you may need to change the answers later.
Does it work on PDFs with no form?+
Yes, but there is nothing to flatten. The tool tells you when a file has no form fields.
Why do some forms fail?+
A few forms use special fonts or characters that cannot be merged. Try simpler text in those fields.
Is my data safe?+
Yes. Everything runs inside your own browser. Your text, files and images are never uploaded to any server.
Is this tool really free?+
Yes — completely free, no signup, no watermark and no usage limit.
