Price: 10x Cheaper for Individuals

Adobe Sign's individual plan starts at $22.99/month billed annually. Business plans begin at $14.99/user/month. SigPDF costs from €2.08/month billed annually with no per-document fees, no envelope limits, and no tiered feature restrictions. For a freelancer or small business that simply needs to sign PDFs, SigPDF is a fraction of the cost.

Privacy: Browser vs Cloud

Adobe Sign is a cloud-based service. When you sign a document with Adobe Sign, it is uploaded to Adobe's servers, processed there, and stored in the cloud for audit purposes. Adobe retains signed documents and associated metadata including IP addresses, timestamps, and authentication records.

SigPDF takes the opposite approach. Your PDF is processed entirely in your browser using client-side JavaScript. Nothing is transmitted over the internet. For documents containing sensitive business information, personal data, or trade secrets, SigPDF provides a fundamentally stronger privacy guarantee.

When Adobe Sign Is the Better Choice

  • You need a verified audit trail for legal or compliance reasons
  • You send documents to multiple signers for collection
  • You require bulk sending or template workflows
  • You need deep integration with Salesforce, Microsoft 365, or other enterprise platforms

When SigPDF Is the Better Choice

  • You need to sign PDFs yourself — not collect signatures from others
  • Privacy matters — your documents contain sensitive or confidential information
  • You want to spend €2.08/month rather than $22.99/month
  • You want no account required, no watermarks, and no per-document limits
