Frequently asked questions
What does flattening actually do?
It merges form fields, annotations, and signatures into the page so they display identically everywhere and can't be changed.
Can a flattened form still be edited?
No — that's the point. Once flattened, the fields become fixed graphics that can't be re-filled.
Is this tool free to use?
Yes. You can use it for free with no account required and no watermark added to your file.
Are my files kept private?
Your file is sent over an encrypted HTTPS connection, processed on the server, and deleted automatically right after your download. Nothing is stored or shared.
