A fillable PDF has real fields built into it: boxes to type in, tick boxes, and lists to choose from. Plenty of readers either hide them or make them awkward to reach, which is why so many people end up printing a form, writing on it by hand, and scanning it back.
Forms usually carry personal details, which is exactly why this runs on your own device. Nothing you type is sent anywhere.
Leaving them unlocked means the form can still be edited, which suits a draft or something a colleague has to add to. Locking makes your answers part of the page, so what the other person opens is what you filled in and nothing can be quietly altered afterwards.
Locking cannot be undone, so keep the blank original if you might need to fill it out differently another time.
Many documents that look like forms are not fillable at all. A form that was printed, filled in by hand, and scanned is simply a picture of a page, and no amount of software will find fields in it because there are none.
For those, the Add Stamps tool can place an image on the page, which covers a signature or an initial. The Sign PDF tool is the better fit if a signature is all you need.
Add your PDF and every fillable field in it is listed with the right kind of input: a box to type in, a tick box, or a list to choose from. Fill them in and download.
Then the PDF has no fillable fields in it. A form that was printed, filled by hand, and scanned holds a picture of the writing rather than any fields, so there is nothing to type into. The Add Stamps tool can place text or a signature image on a page like that.
It makes your answers part of the page, so nobody can change them afterwards. That is usually what you want before sending a form back. It cannot be undone, so keep the blank original if you might need it again.
Those are marked read only by whoever made the form, often because they are calculated or filled in by an office rather than by you. They are shown so you can see what is there, but they cannot be changed here or in any other reader.
The names come from whoever built the form, and some tools generate names like Text1 or field.0 rather than anything readable. Those are what the document itself calls them, so they are shown as they are rather than guessed at.
No. Everything runs inside your browser on your own device. This matters here more than for most tools, because forms usually carry personal details.
