Sign PDF
Let's be real - the digital signature market just exploded from $7 billion to an expected $238 billion by 2034, growing at 39% annually. Why? Because nobody wants to print, sign, scan, and email documents anymore. With remote work becoming permanent and 96% of hospitals already using electronic health records, PDF signing isn't just convenient - it's essential. Our clients sign everything from contracts to consent forms, and frankly, ça fait plaisir to see how much time they save. No more "can you please print this, sign it, and fax it back" nonsense.

Why our PDF signing tool actually matters
Adding your signature to a PDF should be secure, legally binding, and ridiculously simple. Here's how we make that happen:
Cryptographic security
Our signatures use PKI (Public Key Infrastructure) technology to create tamper-proof documents. If someone tries to modify a signed PDF, the signature becomes invalid - providing legal protection and peace of mind.
Compliance-ready documentation
Generate detailed audit trails showing who signed what, when, and from which IP address. Perfect for industries with strict regulatory requirements like healthcare, finance, and legal services.
Multi-signature workflows
Send documents for sequential or parallel signing by multiple parties. Track progress in real-time and get notified when everyone's signed. No more chasing people down for signatures.
Mobile-optimized experience
Sign PDFs directly on smartphones and tablets with touch-screen signature capture. The interface adapts to any device, so urgent documents get signed immediately, not when someone gets back to their desk.
