When you use Adobe tools to collect electronic signatures, you can trust they are secure. The Acrobat online sign tool uses Adobe 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 DC for free for seven days to do more with PDF files on Mac or Windows. Use digital signatures, collect e-signatures with advanced authentication, sign documents yourself with an image of your signature, create templates, edit PDF documents, use cloud storage and convert PDF files to Microsoft Word, PowerPoint or Excel documents. You can work online, on your desktop with Acrobat DC or on your mobile device with the Acrobat Reader app. Free tutorials can get you up and running fast.
