Make read-only PDF form fields fillable again without removing the form.
Some PDF forms ship with their fields locked as read-only so you can’t type into them. This clears the read-only flag and makes the fields fillable again, keeping the form intact. Files are processed securely and never stored.

The author marked the fields read-only, usually to freeze a completed form or to publish a template they did not want altered. The fields still exist and look editable, but the viewer refuses input — which is maddening when you have been sent a form you are expected to complete.
Password removal decrypts a file you cannot open or are restricted from using. This changes the read-only flag on form fields in a document you can already open. Different mechanisms, different problems — if the PDF asks for a password, you need the Password Remover instead.
If it is a blank form you have been asked to complete, almost certainly — the lock is usually an oversight from how it was exported. If it is a finished document deliberately frozen as a record, altering it may not be appropriate. The tool removes a technical restriction; the judgement is yours.
