Smallpdf Announces Sale of PDF Tools, Allowing Smallpdf to Deepen Its Focus on PDF Editing Software

Zurich, Switzerland - July 14, 2026 - Smallpdf AG, the Swiss company behind sign.com and smallpdf.com, one of the world’s most popular PDF software suites, today announced that it has sold its subsidiary PDF Tools to Apryse, a global leader in document processing technology.

Founded in Zurich in 2002, PDF Tools is a provider of high-performance PDF processing software and developer SDKs, trusted by organizations and government entities when quality, accuracy, and consistency are critical for compliance and large-scale document workflows. Smallpdf acquired the company in March 2022. Under Smallpdf’s ownership, PDF Tools has doubled its revenue and continued to expand its product portfolio – most notably with the launch of AI Smart Redact, a self-hosted capability that identifies and securely removes sensitive data from documents with high accuracy.

The sale positions the companies to accelerate on their own paths:

• PDF Tools becomes part of a larger organization serving enterprise customers around the world. Its customers will now operate within the Apryse ecosystem, gaining access to global support, deep domain expertise, and a larger set of capabilities to add to their applications.

• Smallpdf can now double down on its PDF software, serving tens of millions of users per month with secure, easy-to-use tools for managing, compressing, converting, signing, merging, and editing PDF documents.

• Apryse strengthens its high-performance, enterprise-grade document processing offering and expands its footprint in Europe.

"This is a great outcome for both businesses," said Moritz Werner, CEO of the Smallpdf group. "Apryse widens its product offering by adding PDF Tools’ fantastic technology and at the same time expands its global footprint, while Smallpdf can now put its full focus on its consumer and business PDF software platform serving tens of millions of users per month. I am very proud of what the PDF Tools team has built and how the business developed, and I am excited to watch what they do next.”

“PDF Tools brings highly specialized expertise in areas like PDF/A conversion and compression that are critical for our customers. For developers, AI Smart Redaction builds on our success helping teams embed critical AI-powered document workflows directly into their applications,” said Cassidy Smirnow, CEO of Apryse. “By combining that with our platform, we’re not just expanding capabilities - we’re setting a new standard for performance and quality of document processing.”
