The simple e-signature software for signing documents with electronic signature

Enterprise-grade security e-sign web software without the enterprise price tag. Certified, legally binding, and ready in seconds — built for SMBs.

What is an Electronic Signature Software?

An electronic signature web software lets people sign documents digitally — so contracts, agreements, and forms get signed from anywhere, on any computer or mobile device. With QuickSigner, you upload a document, mark where signatures go, and send it to recipients, who sign with a typed name, or a drawn digital signature. Every document is protected by encryption and a complete audit trail, and electronic signatures are legally valid and enforceable for most business documents in most countries, including under the U.S. ESIGN Act and the EU’s eIDAS regulation. And when you’re ready to automate, the QuickSigner eSignature API lets you embed the same legally valid signatures directly into your own product.

What is an Electronic Signature?

Under U.S. federal law, an electronic signature is any electronic sound, symbol, or process attached to or logically associated with a record and executed with the intent to sign it. Every QuickSigner e-signature is a certificate-based digital signature, built on PAdES technology and Adobe Approved Trust List (AATL) certificates. That means cryptographic proof of who signed, tamper-evident protection of the document, and automatic validation when opened in Adobe.

Operational Efficiency

Get agreements signed in minutes, not days. Upload your PDF or Word document, add signers, and send — no printing, scanning, or chasing signatures. QuickSigner e-signatures are legally binding and AATL-certified, backed by ISO/IEC 27001:2022 security, so even the smallest team gets enterprise-grade signing without the enterprise price tag or setup. Less paperwork, faster deals, more time to run your business.

Alternative to DocuSign

Everything you switched to e-signatures for — without the envelope caps. QuickSigner delivers legally binding, AATL-certified signatures with unlimited documents on every paid plan. DocuSign’s Standard and Business Pro plans cap sending at roughly 100 envelopes per user per year, with overage fees beyond that.* QuickSigner starts free, unlimited-document plans start at $48/year, and the e-Sign API costs from $0.30 per document — no per-seat lock-in, no surprise invoices.

Legal Security

Every QuickSigner document is sealed with a certificate-based digital signature and a complete audit trail. QuickSigner e-signatures are backed by Adobe Approved Trust List (AATL) certificate authorities, so they validate automatically in Adobe Reader, and the platform is built on ISO/IEC 27001 security standards. Any change made after signing is instantly detectable — and if a document is ever challenged, you have verifiable, time-stamped proof of who signed what, and when.

Contract Templates

Send the same document twice? Make it a template. Turn any contract, NDA, or form you use regularly into a reusable template — with signature, date, and text fields already placed, and recipient roles ready to fill in. Next time, you skip the setup entirely: pick the template, add the signer’s email, and send. What took ten minutes of dragging fields now takes thirty seconds, and every agreement goes out consistent, complete, and error-free.

Document Management

Mobile Experience

Sign and send from any device — Android, iPhone, iPad, or laptop. QuickSigner runs in the browser, so there’s nothing to install: your signers just tap the link and sign, whether they’re at a desk or in the field. Same full features, same security, every screen size. Business doesn’t pause when you step away from your desk.

Privacy and Security

Your documents are protected at every stage. QuickSigner encrypts data with TLS 1.3 in transit and AES-256 at rest, runs on ISO/IEC 27001:2022-certified infrastructure, and is built to meet GDPR requirements. Role-based access controls ensure only authorized people can view each document, and a complete audit trail records every action — from upload to archive.
