Electronic Signature Software for PDF
Award-winning eSignature solution
What electronic signature software for PDF does
Electronic signature software for PDF lets people sign PDF documents electronically, collect signatures from others, and store a record of the transaction. In a U.S. workflow, the sender uploads a PDF, places signature fields, and sends it for signing by email, link, or mobile device. The signer reviews the document, confirms intent, and applies an eSignature. The system then records timestamps, identity details, and document history, creating an audit trail that helps show who signed, when, and what changed.
Why it matters legally and operationally
Electronic signature software for PDF reduces paper handling, speeds approvals, and supports enforceability under ESIGN and UETA when consent, intent, and attribution are captured. It helps businesses close agreements faster while keeping a record that can support evidence and compliance reviews.
Common PDF signing challenges
Signer confusion can delay completion when the PDF has unclear field placement or instructions. Weak authentication can make it harder to attribute the signature to the right person. Missing audit details can weaken evidence if a signed PDF is later disputed. Poor retention controls can leave signed PDFs outside policy or regulatory recordkeeping rules.

Key features for PDF signing
Electronic signature software for PDF works best when it combines signing speed, document control, and a reliable record of each transaction.
PDF workflow
Upload a PDF, place fields, and send it for signature in one workflow. This reduces manual handoffs and keeps the signing process tied to the original document.
Audit trail
Track signer activity with timestamps, document history, and completion status. The record helps teams review who signed, when they signed, and what happened before final approval.
Templates
Use reusable templates for forms that repeat across customers, patients, or employees. Templates reduce setup time and help keep document structure consistent across many sends.
Mobile signing
Collect signatures on phones, tablets, and desktops without changing the core workflow. Mobile access helps signers finish documents when they are away from a desk.
Signing order
Route documents to one signer or several signers in sequence. This supports approvals that depend on order, role, or department before the PDF is finalized.
Record integrity
Store signed PDFs with a tamper-evident record that supports later review. This helps preserve document integrity and makes it easier to retrieve completed files.
How the signing flow works
The signing process follows a simple sequence from document upload to final storage and recordkeeping.
Prepare document: Upload the PDF and add signature fields. Route for signing: Send the file to one or more signers. Complete signing: Signer reviews and applies the eSignature. Save record: System stores the signed PDF and audit trail.

FAQ about PDF eSignatures
These answers focus on plan features, compliance requirements, and deployment details that matter when PDF signatures are used in U.S. business workflows.
signNow Business includes legally binding eSignatures, audit trails, templates, and mobile apps. For HIPAA use, a BAA is required, and signed records should follow the 6-year retention rule in 45 CFR §164.530(j)(2).
Yes. signNow supports ESIGN and UETA compliance for U.S. transactions when signer intent, attribution, and record retention are captured. The signed PDF and audit trail help support evidentiary review.
HIPAA use requires a signed BAA and controls for access, integrity, and audit logging. signNow’s compliance posture includes HIPAA support, but the covered entity still needs proper configuration and retention practices.
The Business Premium plan adds bulk send, while the Enterprise plan adds advanced signer authentication and formula or conditional fields. If you need SSO or full API access, the Site License is the fit.
signNow supports mobile signing on iOS and Android, and mobile-created eSignatures are valid under ESIGN and UETA when intent and attribution are clear. Native device tools can also create valid SES signatures.
For FDA-regulated records, 21 CFR Part 11 requires secure audit trails, validation, unique signer identification, and two-component signatures. signNow users in regulated environments should confirm workflow validation and access controls before deployment.
