Security Comes First

Security Is First

  • GroupDocs.Signature for Cloud is hosted using industry-leading Amazon EC2 infrastructure which provides state-of-the-art security and guarantees privacy of your documents. All data and document transfers are made over SSL. Read more about our servers' security.
  • All document activities are automatically logged and saved in detailed audit trails.
  • To ensure that the document hasn't been altered at any stage of the signing workflow, GroupDocs uses anti-tampering technology which saves a unique hash record of the document at each stage.
  • Every document signed with GroupDocs is secured with a certificate, which contains critical records, such as each party's full name, IP, email address and other identity details.
Prepare and Send Documents in Seconds

Prepare & Send Documents in Seconds

  • Support for multiple file types. GroupDocs supports literally all business document formats, including PDF, Microsoft Word, Excel, PowerPoint, Outlook and Visio. You can upload a document from your local storage or from your favorite app like Box, Dropbox or Google Docs.
  • Online forms. GroupDocs.Signature enables recipients not only to sign a document online, but also to add data such as address, date, initials, etc. Just drag and drop text fields, check boxes, drop-downs, and other form fields into the document where recipients should enter data before signing it.
  • Expiry dates & reminders. Specify dates by which recipients must sign the document. Send automatic reminders to signers so that they never miss a deadline.
  • Flexible signing workflows. You can send the document to multiple parties at once or enable sequential signing. You can also add CCs, so that all involved parties get a copy of the document once it is signed.
Sign Anytime, Anywhere, from Any Device

Sign Anytime, Anywhere, from Any Device

  • Cross-platform compatibility. There is no need to install or download anything - GroupDocs allows signers to open and sign documents directly in a web-browser and from any web-enabled device, including desktops, laptops, tablets and smartphones.
  • Notification emails. Once a document is prepared and sent, signers receive a notification email, inviting them to sign the document. Recipients need just to click on the invitation link in the email to start the signing process.
  • Easy to follow signing workflow. Interactive flags guide signers through the document by highlighting all the fields that should be filled in and where the document should be signed. This way, signers never miss a single field.
  • Type, draw or upload your signature. Recipients can sign a document either by drawing signatures with a mouse or stylus, by uploading a scanned copy of their signatures, or by typing their initials with a handwriting font.
  • Configurable notifications. Once a document is signed, all parties receive email notifications allowing them to instantly download the completed document in PDF format.
Securely Store and Manage Your Documents

Securely Store & Manage Your Documents

  • Access documents wherever you are. All your documents are stored in GroupDocs’ secure cloud storage so that you can instantly access, share, download and print them anytime, anywhere.
  • View audit trails. See a detailed history for each document to know exactly when the document was created, who signed it, what parties where involved and what other actions were taken.
  • Extensive automation options. Save templates for commonly used documents, recipient contacts, forms and signature images to sign and prepare documents in the blink of an eye.

GroupDocs.Signature’s powerful API allows you to seamlessly add electronic signature functionality to your own application, website or 3rd party service. GroupDocs works great with Content Management Systems (ECM, CMS) and cloud storage providers, allowing users to sign documents online, without leaving the apps they already use.
