About Pdfblocks

PDF Blocks is a PDF automation API and toolset offering operations such as merging documents, adding passwords or restrictions, adding text or image watermarks, and splitting files by page count or file size, with 17 actions in its catalog. It is accessible via a REST API and through no-code connectors for Power Automate (integrating with SharePoint, Outlook, Teams, and Dataverse) and Zapier.

The service processes documents statelessly, holding files in memory only for the duration of a request and not storing or using them for AI training. It offers regional API endpoints in the United States, a dedicated US HIPAA endpoint (available on the Business plan with a signed BAA), Europe, the United Kingdom, Canada, Australia, Japan, India, and Brazil, allowing customers to keep processing within a given country for data residency requirements.

It is aimed at businesses and developers building document workflows, offering a free plan of 100 documents per month with no credit card required, alongside paid plans for higher usage.
