Sign, Stamp, and Annotate PDF Documents in Your Browser
Signing business contracts, non-disclosure agreements, and official forms traditionally required printing physical paper, signing with ink, and scanning the document back to digital format. This wasteful cycle is eliminated with client-side digital PDF stamping.
TabKit allows you to draw your signature directly on screen, upload a transparent PNG signature image, or stamp predefined approval marks (such as Approved, Confidential, or Paid) directly onto PDF pages. Everything executes inside your browser canvas session with zero uploads to remote servers, safeguarding sensitive agreements from exposure.
Frequently Asked Questions
Are electronic signatures placed here legally binding?
In many jurisdictions (including under the US ESIGN Act and EU eIDAS regulations), electronic signatures on commercial contracts are legally recognized when both parties agree. For highly regulated documents requiring cryptographic certificates, consult legal counsel.
Can I upload a pre-drawn signature image?
Yes. You can draw your signature using a mouse, stylus, or touchpad, or upload an image file with transparency for exact positioning and scaling.
Is a copy of my signature or signed document saved on any server?
No. TabKit operates with zero server storage. Your signature image and PDF documents exist only in your current browser memory and are deleted once the tab is closed.
