Our Top Picks: Digital Signature Software Reviews

Although the terms electronic signatures and digital signatures are often used interchangeably, the two are not synonymous. An electronic signature (or e-signature) is any mark or image used to sign a digital document. For example, an e-signature can be a JPEG file of a hand-written signature or a name stamp. Digital signatures, on the other hand, are e-signatures that employ encrypted data to keep an audit record of changes to a document. 

Digital signatures are authenticated using identifying elements such as passwords, two-factor authentication (2FA), biometric information, and device data such as an IP address to confirm the identity of the signing parties. 

The software we’ve chosen all excel in their own particular area. We’ve pointed out best overall, best for individuals, best for businesses, and best free service so you can decide on the perfect digital signature software for your needs.

Our Research

Further Insight Into Our Methodology

In the U.S., businesses spend an estimated $8 billion annually on paper, mailing, printing, and document handling. However, companies that employ digital signatures can reduce document handling expenses by up to 85%. Not only can digital forms save money, but they can reduce lost or misplaced documents and turnaround time by 80%

Our research focused on finding digital signature services with strong security practices and a proven track record in helping customers reduce document handling efforts and turnaround time. We compared individual plan structure and prices for each service, as well as their features and customization options. We also looked for software in compliance with the U.S. ESIGN Act, only considering those with transparent information on software architecture compliance, security certificates, and identity authentication. Lastly, we looked at integration options, mobile applications and customer support, as well as any specific feature that would make a particular software stand out. 


Features

Digital signature software helps businesses reduce paper and cut costs. Because of this, we looked for services with unlimited document signature and storage. Most digital signature services offer an array of features to facilitate online document signing, such as real time tracking and notifications that allow users to monitor document changes and follow through the signing process. With the exception of our Best Free Digital Software pick, all of our digital software recommendations offer contract templates and customizable fields, as well as multiple language options. All the services recommended have iOS and Android native apps and offer live support via chat or phone.

Other features include:

Custom signing features

  • Digital Certificate (PKI) Signature
  • Electronic Signature Pad Capture
  • Handwritten Mouse Signature
  • Standard Scripted (Typed) Signature
  • Company logo

Document sending

  • Bulk emails
  • Document previews
  • Multiple signers
  • Office documents (PDF, excel, word)
  • Email branding

Document management

  • Administrator privileges
  • Multiple users
  • Workflow management

Reporting Features

  • Document signing alerts
  • Document viewing alerts
  • Downloadable reports
  • Expiration notifications

Security

We examined each service's security protocols and certifications looking for services in compliance with the U.S. ESIGN Act. Only documents created with password-protected, strong authentication protocols and encryption, and two-factor authentication can produce legally binding digital signatures. Documents should also have public key infrastructure (PKI) auditable data records to create legally binding agreements. We favored services that employ bank-level data security and SOC-compliant encryption, with information on their security protocols, data storage policies, and external audit practices. 


Integration

We examined system integration options such as API, connectors, cloud storage, and document management apps. We favored services that list their integrations and compatibility across operative systems, devices, and platforms—preferably working with today’s most used applications, such as Salesforce, Workday, SAP, Microsoft, Google, ORACLE, Apple, Intelledox and Seal, among others.


Pricing

There are several factors to consider when comparing digital signature services. Does it allow multiple signers or do you have to obtain several licenses for multiple users? Do you prefer a monthly or annual subscription? We looked at payment options and additional fees, as well as basic free options for casual users, and chose services that won’t charge additional fees for basic features. We also favored digital signature software without a maximum signature or document quotas. Services with per signature, envelope, or other unclear payment schemes have been vetted from our recommendations.

Helpful Information on Digital Signature Software

Digital signature software is generally built to fulfill four needs: a means of signing, authenticating and validating signatures, as well as a way to authenticate a document’s data. To this end, digital signature technologies employ items such as passwords, personal identification numbers (PINs), two-factor authentication, biometric markers, and time-stamped audit logs to validate the identity of the parties involved. In comparison to e-signatures, digital signatures add strong layers of security, global acceptance and legal compliance, long-term document retention and access, and independent verification to create legally binding signatures.

What To Watch Out For With Digital Signature Software

Limited Signature Quotas

Some digital signature software services still employ limited document or signature quotas on their plans. While these services are legitimate and possess many of the features included in our recommendations, for the same monthly price, our picks offer comparable software capabilities with unlimited documents and signatures, making quota-limited options pretty much obsolete in terms of value and practicality when compared with similarly priced unlimited options. 

Legally Binding Signatures

Although the ESIGN Act makes digital signatures admissible in court, state and federal law may require that digital signatures comply with specific data management protocols and certifications. If you are dealing across state lines or with signers in other countries, it would be best to read up on each service’s security and legal terms to make sure the selected software complies with local law requirements.   


FAQs about Digital Signature Software


Can digital signatures be forged?

All digital files and records can be hacked. However, digital signatures are encrypted and possess an audit trail that will record any changes or tampering. Encrypted documents are extremely hard to crack as the information requires that multiple keys are deciphered and any attempt to change the information alters the data file permanently.


Are digital signatures legally binding?

Digital signatures are legally binding. In the US, the ESIGN Act and the Uniform Electronic Transactions Act (UETA) describe what constitutes legally binding digital signatures. These laws confer digital signatures the same legitimacy as handwritten signatures. Software is made to comply with public Key Infrastructure (PKI), security certificates, and data management protocols. 


Does a digital signature show up as your actual handwritten signature?

This depends on the digital signature program you select. Some programs will simply add your signature as text, while others use a copy of your signature. Either way, the digital signature appears with a seal which the recipient can view to confirm the identification of the signer(s).


Do you retain access to signed documents if you unsubscribe a service?

Each software provider has its own document storage policy. Before you contract or terminate a service, make sure that you understand what type of access you’re entitled to as well as how long your documents are stored. A good way to keep documents organized and safe is by storing them in a document vault such as those provided with password managers.


How do you know that an actual person is signing the document and not a robot or someone else?

Digital signature software combines user data to authenticate the identity of the signers. Information such as full names, email addresses, IP addresses, and time stamp data, combined with sign-in securities such as biometric, two-factor authentication (2FA) is stored in the files audit trail and serves to corroborate the identities of the signers.
