PDF4me API provides document-processing endpoints and SDKs for developers, alongside browser-based PDF tools. The API supports conversion, OCR, signing and parsing; the web tools can convert, merge, compress, split, sign and edit PDFs. AI processing can parse invoices, classify files and extract structured data as JSON. SDKs are available for C#, Java, Python, JavaScript (Node.js) and Salesforce Apex. Listed integrations include Power Automate, Make, Zapier, n8n, RapidAPI, Microsoft Teams and Google Workspace, and the maker also offers no-code automation for workflow builders.
