PDF.co is a cloud-based REST API platform designed to automate PDF-related tasks such as extraction, conversion, editing, and creation. It aims to cut the manual effort involved in processing PDFs by providing a set of low-code, secure endpoints that developers and non-developers can integrate into apps, websites, and automation workflows. With more than 3,000 integrations, it slots into popular platforms like Zapier and Google Sheets to streamline document-heavy business processes. At its core, the platform offers a broad toolkit: PDF-to-X conversion, merging and splitting, fillable form creation and filling, e-signatures, security controls, barcode reading/generation, compression, and even HTML/email-to-PDF generation. Newer AI features include invoice parsing and document classification, allowing users to extract structured data from documents without creating templates. The API is request-based, HTTPS-secured, and backed by documentation with code samples, giving teams a fast path to production. PDF.co is trusted by over 50,000 users, including major organizations such as Accenture, KPMG, PwC, Deloitte, Fujitsu, and Siemens. It is especially useful for finance/accounting teams, operations managers, and software developers who need to remove repetitive PDF work or embed document processing into larger systems. A free trial of 10,000 credits is available for one month with no credit card required.
