pdfRest is a PDF processing API built on the Adobe PDF Library: more than 40 tools convert HTML and Office files to PDF, compress, merge, split, OCR, redact, encrypt, watermark and digitally sign existing PDFs, and import, export and flatten form data. It runs on US or EU cloud endpoints, as a self hosted container or from AWS Marketplace, and states SOC 2 Type 2, HIPAA and GDPR compliance. It processes files you already have rather than generating documents from templates and data, which makes it a different offer to PDF Generator API. The comparison below breaks down where each fits.

pdfRest alternative: which one fits
pdfRest covers the processing side of PDF work in depth: conversion from HTML, Office files and images, PDF/A and PDF/X output, OCR, redaction, encryption, digital signatures, watermarks, form data import and export, and XFA to AcroForm conversion, all on the Adobe PDF Library. Its compliance story is specific, with SOC 2 Type 2, a HIPAA BAA, an EU endpoint for GDPR, and a self hosted container for full data residency, and its per call prices are low. It fits developers who need to transform, secure or archive PDFs they already produce, including in regulated industries. It does not generate documents from a template and JSON data, so loops, conditional sections, a template designer and template management sit outside it.
PDF Generator API starts one step earlier: it generates the document from a template and JSON, with a drag and drop embeddable editor your own customers use, loops and conditional sections, existing PDFs used as templates, web forms that collect data, and signature fields and document signing. It also covers HTML to PDF, fillable forms, watermarks, merging and encryption, accessible PDFs and electronic invoices, with ISO 27001 certification, GDPR and HIPAA coverage, and dedicated or on premises deployment. For pure conversion and post processing at low volume, pdfRest costs less per call. If you generate documents today and post process them in pdfRest, build one template in the free trial and run the same steps through our PDF services endpoints.
pdfRest vs PDF Generator API: FAQ
Is pdfRest cheaper than PDF Generator API?
At low volume, yes: pdfRest costs $9.99 a month for 600 calls, against €8 for 50 credits. At 5,000 a month the prices are close, $99.99 for 5,000 pdfRest calls against €88 for 5,000 credits, and PDF Generator API adds template based generation with an embeddable editor, which pdfRest does not offer.
What is the difference between pdfRest and PDF Generator API?
pdfRest works on PDFs you already have: conversion, compression, OCR, redaction, encryption and signing. PDF Generator API generates the document first, from a template and JSON data, with loops, conditional sections and an embeddable editor, and also offers PDF services for forms, watermarks, merging and encryption.
Can pdfRest run on premises?
Yes. pdfRest offers a self hosted container from $124.99 a month and an AWS Marketplace image. PDF Generator API also offers on premises deployment, plus dedicated cloud deployment in the US, EU, UK or Australia.
