Is this document a SignSwifly original?

Choose a signed PDF, a certificate of completion or a combined document you were sent or downloaded from SignSwifly. We’ll tell you whether it is exactly the file SignSwifly sealed, so nothing in it has changed since.

Your file never leaves your device. Your browser works out the file’s SHA-256 fingerprint, a 64-character code that changes completely if even one byte of the file does, and only that code is sent to us to look up.

If it isn’t found

We only recognise the exact file SignSwifly produced. A copy that has been edited, re-saved, printed to PDF, compressed or signed again in another program has a different fingerprint, even if it looks the same. Ask the sender for the original download, or contact us with the SignSwifly ID printed at the top left of each page.

Adobe says the signature has problems?

SignSwifly seals documents with its own certificate while it moves to one on Adobe’s Approved Trust List Coming soon. Until then, Adobe can’t name who sealed the file. This page confirms that SignSwifly sealed it, and that it hasn’t changed since.
