pdfRest
pdfRest is a developer PDF API with 40+ endpoints for conversion, extraction, and document manipulation. Convert to and from PDF (Word, Excel, PowerPoint, images, PDF/A, PDF/X). Merge, split, compress, and linearize. Extract text, images, and metadata. Add OCR to scanned documents. Watermark, encrypt, decrypt, restrict, and redact. Fill, flatten, import, and export form data. Requests are chainable, so multi-step document pipelines run in sequence without shuttling files back and forth between calls.
What sets pdfRest apart in the PDF API space is deployment flexibility. Most PDF APIs are cloud-only. pdfRest ships three ways: Cloud, Container and AWS Marketplace.
For teams running an evaluation: pdfRest is SOC 2 Type 2 audited and supports GDPR and HIPAA requirements. The Container deployment is the strongest fit for regulated workloads, specifically because processing happens entirely inside your own environment.
