Draw Signatures with On-Screen Signing

ONLYOFFICE Docs is a comprehensive online editor, allowing users to create text documents, spreadsheets, presentations, and forms. It enables your users to edit, share, and collaborate on documents online in their preferred browser, within your own application. It is fully compatible with OOXML (Office Open XML) formats and supports popular Microsoft Office and other document formats such as CSV, DOC, DOCX, EPUB, HTML, ODP, ODS, ODT, PDF, PPT, PPTX, RTF, TXT, XLS, and XLSX.

The ONLYOFFICE Docs v9.3 update enhances PDF form functionality by introducing flexible signature input methods, including typed, drawn, and image based signatures with background removal, together with support for trusted digital certificates managed through the Admin Panel. These capabilities allow developers to implement more adaptable and user friendly document signing experiences across desktop and touch devices while strengthening security through verifiable digital signatures. As a result, applications built on ONLYOFFICE Docs can ensure document authenticity, prevent unauthorized modifications, and meet enterprise requirements for secure electronic form submission.
