Sign PDF Online Free — No Upload Required
Draw, type, or upload your signature and place it anywhere on your PDF. Your document never leaves your browser — no DocuSign account needed.

Drag & drop a PDF to sign
NDAs, contracts, forms — any PDF
Sign PDFs privately — no account, no upload
Most PDF signing tools (DocuSign, Adobe Sign, HelloSign) require you to upload your document to their cloud servers. That works fine for routine forms, but for NDAs, employment contracts, lease agreements, or anything confidential, uploading to a third party introduces unnecessary risk.
SimpleTool's PDF signer runs entirely inside your browser using pdf-lib and pdf.js — both open-source libraries that run as WebAssembly in your browser tab. Your PDF is never transmitted to any server. Draw your signature with a mouse or trackpad, type it in a handwriting-style font, or upload an existing PNG — then drag it anywhere on the page and download the signed PDF.
Your document stays private
The PDF never leaves your browser tab. No server ever sees your contract, NDA, or form. Zero upload means zero breach risk.
Three ways to sign
Draw with your mouse or finger, type your name in a handwriting font, or upload a PNG of your existing signature.
No account needed
Sign unlimited PDFs for free with no daily limit, no registration, and no subscription. Your saved signature stays in your browser.
When to sign a PDF without uploading it
NDAs and freelance contracts
Non-disclosure agreements contain trade secrets and business strategies you cannot expose to a third-party server. Sign locally, send by email.
Lease agreements
Rental contracts include your home address, ID numbers, and financial history. Sign privately in your browser before returning to your landlord.
HR and employment forms
Offer letters, equity agreements, and benefits paperwork often contain salary terms. Signing locally keeps your compensation private.
Medical consent forms
Health information is among the most sensitive data you have. Sign and return consent forms without routing them through a cloud signature provider.
Legal documents
Settlement agreements, power of attorney, and court filings are privileged. Sign them in your browser where attorney-client privilege can remain intact.
Quick forms and permissions
School permission slips, HOA forms, and consent letters don't need a full DocuSign workflow. Open in browser, sign, download, done.
