Why a signature tool needs to be simpler.

Most e-signature tools are enterprise workflow engines. You don't need a workflow. You need to sign a PDF.

Upload, sign, download. No registration, no verification emails, no dashboard.
Real PDF output
Your signature is embedded into the PDF server-side. Not an overlay. Not a screenshot. A real signed document.

FAQ

Is this legally binding?
Electronic signatures are generally recognized under ESIGN and UETA. For everyday documents — leases, waivers, NDAs — you’re good. Not intended for regulated compliance workflows.
Do I need an account?
No. Self-signing is free, no account required. Sending for signature costs $5 per document — just enter your email at checkout.
What can I add to a document?
Signatures (draw, type, or upload), initials, dates, and text fields. Text fields work for anything — printed name, address, phone, email, company. Free users get 2 text fields, paid gets unlimited.
How long are documents stored?
Free self-signed documents auto-delete after 24 hours — download yours immediately. Paid documents are stored permanently.
Can I send to multiple signers?
Not yet. SignTh.is is designed for single-signer documents. One sender, one recipient.
