How to unlock iPhone PDF in ‘files’

So I had this problem where I locked a PDF and didn’t want to, so I looked how to get rid of it.

After an entire hour I figured it out, and will share it so no one else suffers like I did.

1: you need to download an app called ‘PDF Expert: Read, Edit, & Sign’

2: Scroll down and find ‘Set Pasword’

3:click files

4: press the file you want to unlock.

5: Press the ‘…’ in the top left corner.

6: press ‘change password’.

7: press ‘remove current password’.

8: DONE!
