QuickSigner is an electronic signature platform that lets you sign, send, and finalize documents online with legally binding, AATL-certified digital signatures on a browser-based system.
What is QuickSigner?
QuickSigner is a cloud-based e-signature solution that turns PDFs and Word documents into signed, tamper-evident contracts. You upload a file, place signature and date fields, then send a secure link to recipients who sign from any device with a click or drawn signature. The platform is built by QuickSigner (no parent company named on the page), runs entirely in the browser with no software to install, and seals every document with an Adobe Approved Trust List (AATL) certificate for automatic validation in Adobe Reader.
Key Features
- AATL-certified digital signatures — Every signature is a certificate-based PAdES digital signature that validates automatically in Adobe Reader, backed by Adobe Approved Trust List certificate authorities.
- ISO 27001:2022 security — The platform operates on ISO/IEC 27001-certified infrastructure with TLS 1.3 in transit and AES-256 at rest encryption, plus full audit trails.
- Unlimited documents on paid plans — Business and Professional plans include unlimited document sends per month; the free plan allows 3 documents per month.
- Mobile-ready browser experience — No app download required: signers receive a link and sign on any device (Android, iPhone, iPad, laptop) with full feature parity.
- Document management — Upload PDF and Word files, save reusable templates (up to 10 on Business, more on Professional), search/filter by tags, and track signing status in real time.
- Bulk send and e-Sign API — Professional plan includes bulk sending and an e-Sign API (50 free credits, then US $0.30 per document).
- Role-based access and audit trail — Only authorized users can view documents; every action from upload to archive is recorded in an immutable audit log.
Who is it for?
- Small business owners — Send NDAs, invoices, and client agreements with unlimited documents on the Business plan ($5/user/month) and no envelope caps.
- Freelancers and occasional signers — Use the free plan to sign up to 3 PDFs per month with AATL sealing and AES-256 encryption, no account required for recipients.
- Teams needing API integration — Developers on the Professional plan can integrate e-signing into their own apps using the REST API at $0.30 per document after 50 free credits.
What can you do with QuickSigner?
- Send contracts for signature — Upload a lease or sales agreement, add up to 10 signers (50 on Professional) in a defined signing order, and let each recipient sign from a secure email link.
- Collect signatures from multiple parties — Use the "sign in order" setting to route a document through approval stages, with reminders and real-time status tracking.
- Create document templates — Save frequently used contracts (e.g., employment offer letters) as templates with pre-placed fields, then generate new sign requests in seconds.
How does QuickSigner work?
- Upload a PDF or Word document from your device.
- Add signer email addresses and drag signature, date, checkbox, or attachment fields onto the document.
- Each recipient receives a secure link by email and signs from any browser — no account needed.
- Track progress in real time; once all parties sign, the completed AATL-sealed document is delivered to all signers.
