About DocuSeal
DocuSeal is a document signing tool for filling, completing and electronically signing documents, including custom PDF forms. It is available as a hosted service or can be self-hosted, and the site states it is free forever for individuals while remaining extensible for businesses and developers. Documents can be sent from a connected company email account and branded with a logo and name.
For developers, DocuSeal provides a REST API, SDKs, webhooks and embedded signing or form-creation components, plus automation through Zapier, Make.com and n8n. Teams can manage access permissions, roles and SAML SSO. Supported formats are PDF, DOCX, XLSX, JPEG, PNG and ZIP, with a maximum file size of 100MB.
