When you use Adobe tools to collect electronic signatures, you can trust they are secure. The Acrobat online e-signature solution uses Acrobat Sign technology to make sure signers can’t change the agreement after they add signatures, protecting signed documents from tampering. In addition, you can track and manage all sign requests — creating a valuable audit trail with timestamps.
You can also try Adobe Acrobat Pro for free for seven days to do more with PDF files on Mac or Windows. Use digital signatures, collect e-signatures with advanced authentication, fill and sign forms, sign documents yourself with an image of your signature, create templates, edit PDF documents, use toolbar and annotation functionality, use cloud storage, create fillable PDF forms and convert PDF files to Microsoft Word documents, PowerPoint docs or Excel formats. You can work online, on your desktop with Acrobat or on your mobile device with the Acrobat Reader mobile app. Free tutorials can get you up and running fast. Third-party integrations can also make your document workflows more efficient.
