The Problem With Other PDF Tools
Adobe Fill & Sign is built into a massive, expensive ecosystem. If you just need to sign a PDF occasionally, you shouldn't need an Adobe subscription or even an Adobe account. SignifyPDF gives you the same result for free.
Why SignifyPDF Is the Safer Choice
Adobe's free tier is limited, ad-supported, and requires a login. SignifyPDF requires nothing — open the site, sign your PDF, download it. That's it. No ecosystem lock-in.
