PDF4me API vs PDFMonkey

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. Most endpoints use one call per document, while high-quality conversions, OCR and AI features use one call per page. The service says documents are processed in EU or US regions depending on account setup, deleted within minutes after completion and not retained for training. Free one-time call packs are listed from 500 to 25,000 calls. A custom sales option is listed for more than 25,000 calls, without a stated price.

PDFMonkey is a cloud document-generation API that turns templates and dynamic data into files. Templates can be built in a visual drag-and-drop editor or written in HTML, CSS, and Liquid; JSON data can be sent through the REST API to generate documents. Its Chrome-based renderer supports JavaScript, external fonts, images, charts, and other web technologies. Outputs include PDF, PNG, WebP, and JPG, and bulk generation from datasets is supported. Connectors include Zapier, Make, n8n, Workato, Bubble, Glide, and InvoiceBerry; developer tools include Ruby and Node.js SDKs and webhooks. API traffic uses HTTPS/TLS, dynamic data is stored in encrypted database columns, and generated files are kept in private S3 buckets with one-hour presigned URLs. PDFMonkey states that it has no formal SOC 2 or ISO 27001 certification. The free plan allows 20 documents per month with one-day retention and a 30-second generation limit, and excludes external images, fonts, CSS, and JavaScript. Paid plans start at €5/mo.
