Sign documents that hold up
Upload a PDF, drop your signature where it belongs, and get back a file that is cryptographically sealed — not just a picture pasted on a page. Any edit after signing breaks the seal, and the reader says so.
No credit card required. The free plan stays free, paid plans from R180/month.
What you get back
PAdES-B-B-
01
A visible signature Your own ink, lifted off a photo with the paper removed, placed where you drag it.
-
02
A cryptographic seal over the whole file PAdES/CMS, RSA-3072 with SHA-256, covering every byte.
-
03
Tamper evidence Change one character afterwards and verification fails. We test this on every build.
-
04
A certificate of completion Who signed, when, from where, and the document's SHA-256 — kept after the file is gone.
How it works
Four straightforward steps from unsigned document to cryptographically sealed PDF.
Create an account
Email and a password. Nothing else is asked for, because nothing else is needed.
Add your signature
Photograph your signature on paper and upload it. The paper and its shadows are removed automatically. Company emblems keep their colour.
Place it
Upload a PDF, drag the signature onto the page, resize and tilt it. Works with a mouse or a finger.
Download the sealed file
The visible mark goes on first, then the cryptographic signature covers it and everything else.
Your documents do not stay here
Every uploaded file — and the signed copy — is deleted 60 minutes after upload. That is enforced by a sweeper and re-checked on every read, so an expired document cannot be served even between sweeps. Download what you need before the timer runs out. You can also delete anything immediately.
