Signing a PDF you already have
The document exists. An attorney wrote it, it has your letterhead on it, and nobody is retyping it into anything. It just needs signing.
Your own PDF, signed where you say, returned as a sealed PDF with the evidence attached — rather than a template you have to rewrite in somebody else's editor.

Not a feature list. These are the three moments this exists for.
Retyping it into a template editor means somebody has to check, word by word, that the retyped version says what the reviewed one said. Nobody does that, which is the problem.
The scan that comes back is grey, rotated, missing page three, and proves nothing about who held the pen.
A signature box halfway over a paragraph looks like what it is — somebody rushing — and it is the first impression a customer gets of how carefully you work.
The real pages, at a size you can read, with the fields you place shown where they will actually appear.
Signature, initials, date and text, assigned to a signer, marked required or not. Several signers on the same document each get their own.
The same document with the values stamped in, sealed, with the certificate and the evidence behind it and a hash anybody can check.
The sealed PDF is signed with SignSealer's own key. That is a real cryptographic seal and it detects any change to the document. It is not issued by one of the certificate authorities a PDF reader trusts out of the box, so a reader may show the signature as being from an unrecognised issuer rather than with a green tick. We would rather say that plainly than let a tick imply something we have not bought. The check page confirms the document independently, which is the part that actually proves anything.
The same document, sent by businesses that have nothing else in common.
No. It can be a flat PDF with no fields at all — you place the fields, and the original file is never modified, only stamped on the way out.
Yes, each with their own fields, in order or all at once, and the finished file carries all of them.
Yes, without an account. The certificate has a code, and the check page confirms the document's hash and the signatures against it.
