Does this remove signature fields?

It removes the editable widget appearance. Cryptographic digital signatures (PKI) are stored separately in the document and may still be present — use Sign PDF Verify to check.

Will form data be lost?

No — form fields are FLATTENED before removal, so the filled-in values are baked into the page as static text. The form just becomes uneditable.

Is this enough to make a PDF safe to open?

Removing JavaScript stops scripts from running in a viewer. It does not protect against exploits in the viewer's parser itself — keep your PDF reader updated regardless.

How does the PDF Cleaner (Strip Comments, Forms, Scripts) work?

PDFs you receive from clients, suppliers, or external tools often carry a load of interactive cruft you don't want to ship onward: comments / sticky notes from review cycles, form fields that no longer make sense in the final document, JavaScript actions that fire on open (possibly hostile). This tool runs a one-shot sweep that removes ALL of them in a single pass — pick the three toggles you want (default: strip everything) and download a clean copy. Annotations are dropped from the page /Annots arrays; form fields are flattened to static content first (so filled-in values survive), then the AcroForm entry is removed; JavaScript actions are wiped from the catalog OpenAction + /AA and from every page's /AA. Pair with Compress PDF afterwards if you want to also drop the unreferenced JS object bytes from the file.
