What Flatten PDF will do
Flattening turns filled form fields, signatures and comments into part of the page, so they look the same everywhere and can't be edited.
Your files never leave your device
PDFSleek runs the editor inside your browser. Your PDF is opened, edited and saved on your computer — it isn't uploaded to us, so there's nothing for us to read, keep or lose.
