Office to PDF PHP Overview
Our Microsoft Office to PDF PHP SDK converts Word, Excel, and PowerPoint files into pixel-perfect PDFs through a single endpoint, with no Microsoft Office license or installation required. It accepts the full Office range, including modern and legacy formats such as docx, doc, rtf, xlsx, xls, csv, pptx, and ppt, and reproduces your original fonts, images, tables, charts, and page layout exactly.
Open password-protected documents and generate PDF/A output for long-term archiving and compliance. Files are processed on our SOC2-, ISO 27001-, HIPAA-, and GDPR-compliant infrastructure, and you can keep everything in memory or use secure temporary storage that deletes automatically.
From automated invoice and report generation to bulk archiving of signed contracts and presentation decks, the PHP SDK fits straight into your document pipeline. It handles everything from a one-page memo to complex multi-sheet workbooks and image-heavy slides, and over 1,100 companies worldwide rely on it in production.
