IronPDF

Start by treating PDFs as an output you can generate on demand from your .NET apps. With IronPDF, you can render HTML, Razor views, or URLs into PDF files as part of your normal workflow—generate invoices after checkout, create receipts from order data, or export reports from dashboards. Save to disk, stream to the browser, or attach the result to an email job without leaving C#.

When your users need to find and reuse information, build a simple intake pipeline. Import existing PDFs, extract text, split or merge pages, and add headers, footers, and page numbers before re-saving. For scanned documents, pair PDF processing with OCR to turn images into searchable text, then push key fields into your database or a validation screen for review.

For automation and integrations, connect documents to identifiers and tracking. Generate QR codes or barcodes, stamp them onto PDFs, and later read them back to route files through your system. You can also create Excel exports for stakeholders, or scrape structured data from documents and web sources to keep internal records synchronized.

In day-to-day development, the library fits into CI/CD and background processing. Write unit tests around PDF output, run batch jobs to re-render templates, and ship consistent documents across environments. The goal is predictable document generation and processing that stays inside your existing C#/.NET codebase.
