Flatten PDF
Flatten PDF forms so they can't be edited anymore. Fast, free, and fully client-side.
How the Flatten PDF Works
Bakes all interactive form fields directly into the PDF page, locking them in place permanently.
Usage Example
Lock a finished tax form before submitting it so no one else can edit it.
Frequently Asked Questions
Can I un-flatten it later?
No, once flattened, it's permanent. Save a copy of the original if you think you'll need to edit it later.
