Compressing a Word Document by API, the Same Way You'd Compress a PDF

PDF4me is a document automation platform built by Ynoox GmbH in Hedingen, Switzerland. We publish here about the unglamorous parts of document processing: the ones that look trivial until you try to automate them at volume. Converting a scanned invoice into structured data. Splitting a thousand-page batch on a barcode. Choosing between nine compression profiles when you only wanted a smaller file. Getting a Word template to merge cleanly into a thousand personalised PDFs without opening Word. What we cover: Conversion between PDF, Office formats, images, HTML and Markdown, including PDF/A for archival and ZUGFeRD and Factur-X for European e-invoicing. Extraction and parsing. OCR, table extraction, regex against page text, and schema-driven AI parsing for invoices, receipts, contracts and payslips. Document operations. Merge, split, organise, stamp, watermark, sign, redact page ranges, repair damaged files, and read or generate barcodes including Swiss QR. Word, Excel and image processing over the same API, not a separate product. Everything is available as a REST API, and through Power Automate, Make, Zapier and n8n for teams building without code. There is an MCP server and an agent skills package for anyone wiring documents into AI tooling. Posts here include working code, not pseudocode. If a claim is made about an endpoint, there is a request you can run to check it. Docs: docs.pdf4me.com API portal: dev.pdf4me.com Tools: pdf4me.com
