# TX Text Control .NET Server > Create, edit, convert and sign DOCX and PDF documents in .NET on Windows and Linux: server-side processing, mail merge, a browser editor and viewer, and AI. - **Product:** TX Text Control .NET Server - **Kind:** Topic - **Path:** TX Text Control .NET Server - **1342 words** - **Web URL:** https://docs.textcontrol.com/tx-text-control-dotnet-server/ - **LLMs URL:** https://docs.textcontrol.com/tx-text-control-dotnet-server/llms.txt - **LLMs-Full URL:** https://docs.textcontrol.com/tx-text-control-dotnet-server/llms-full.txt --- TX Text Control .NET Server is a set of components for document processing in .NET applications. Your code creates, loads, changes, converts and saves documents on the server, and your users edit, read, fill out and sign them in the browser. All of it runs on one document engine, so a template designed in the editor is the same document your backend merges with data and saves as PDF. Nothing else has to be installed alongside it. TX Text Control reads and writes DOCX, RTF, HTML, PDF and the other formats itself, so no Microsoft Word and no Adobe Acrobat are involved, and with the Core engine the same application runs on Windows and on Linux, in a container or in an App Service. ### What You Can Build | Task | Read | |---|---| | Generate invoices, contracts and reports from a template and your data | [Mail Merge and Reporting](https://docs.textcontrol.com/tx-text-control-dotnet-server/mail-merge/llms-full.txt) | | Create, change and convert documents in code, without a user interface | [Document Processing](https://docs.textcontrol.com/tx-text-control-dotnet-server/document-processing/llms-full.txt) | | Give users an MS Word compatible editor in the browser | [Document Editor](https://docs.textcontrol.com/tx-text-control-dotnet-server/document-editor/llms-full.txt) | | Let users read documents, annotate them and fill out forms | [Document Viewer](https://docs.textcontrol.com/tx-text-control-dotnet-server/document-viewer/llms-full.txt) | | Create PDF, PDF/A and accessible PDF/UA documents, or import and change existing PDFs | [PDF Processing](https://docs.textcontrol.com/tx-text-control-dotnet-server/pdf/llms-full.txt) | | Sign documents with a certificate, and validate the signatures | [Digital Signatures](https://docs.textcontrol.com/tx-text-control-dotnet-server/digital-signatures/llms-full.txt) | | Summarize, analyze and chat with documents using a language model | [AI Integration](https://docs.textcontrol.com/tx-text-control-dotnet-server/ai/llms-full.txt) | ### Who This Documentation Is for It is written for .NET developers, and it assumes you know C# and the framework you are building on.
