Sign Contracts, NDAs & PDFs Online Without Printing
The Free, Zero-Upload Alternative to Cloud E-Signature Subscriptions
Need to sign a Non-Disclosure Agreement (NDA), job offer letter, apartment lease, or IRS form, but don't want to print, sign with a pen, and scan it back in?
Meanwhile, heavyweight cloud platforms like DocuSign or Adobe Sign charge $15 to $30 per month, force you to register an account, and store your sensitive salary figures and private agreements on third-party cloud servers.
PDFSeal Sign & Stamp lets you execute documents in under 60 seconds—100% locally in your browser, with zero uploads, zero accounts, and crisp vector-grade quality.

❓ Frequently Asked Questions (FAQ)
Can I sign a PDF and send it without printing the document first?
Yes. With PDFSeal Sign, you can open any PDF in your browser, draw your handwritten signature or upload a transparent stamp image, place dates or text, and export a clean, flattened PDF ready to email or fax online.
Is my confidential NDA or employment contract uploaded to a server?
No. Unlike cloud e-signature platforms that store your contracts on remote databases, PDFSeal executes 100% locally inside your browser. Neither your document nor your signature image ever leaves your device.
Do I need to create an account or pay a monthly subscription?
No. PDFSeal is completely free and open-source (AGPL-3.0). There are no sign-ups, no document quotas, and no recurring subscription fees.
