RasterEdge is a Singapore-based document imaging solutions provider focused on its .NET Document Imaging SDK. Its product line centers on the EdgeDoc document viewer, EdgePDF PDF editor, XDoc document SDKs, and XImage image SDKs, enabling document-processing capabilities to be embedded into ASP.NET, Windows Forms, WPF, and other applications.
Based on the site content, its feature coverage is quite broad: online viewing for PDF/Word/Excel/PowerPoint/TIFF/DICOM/images/XPS; PDF annotation, redaction, text and image editing, page processing, permissions and password handling; format conversion, compression, merging and splitting, text and image extraction; plus OCR, TWAIN scanning, and barcode reading and generation. The HTML5 Web Viewer uses JavaScript client-side controls and communicates with a server-side WebHandler, with no browser plugin required. It supports C# and VB.NET, with scenarios including ASP.NET Core, MVC, WebForms, IIS, Azure, SharePoint, DNN, WPF, and Windows Forms. It also mentions older technologies such as Silverlight and IE9+.
The website provides Free Trial, Purchase, and Pricing entry points, but the crawled content does not show specific prices, licensing models, or payment methods, so buyers should contact the vendor or check the purchase page before procurement. Documentation includes online demos, developer guides, and many how-to articles, such as running the Web Viewer, integrating controls, loading documents, PDF annotation, saving/exporting, and customizing the UI. The upside is broad coverage; the downside is that many pages are repetitive, the information architecture feels somewhat traditional, and guidance around modern package management, REST APIs, and CI/CD integration is not very visible.
Its strengths are broad .NET ecosystem compatibility, support for many document formats, and a fairly complete feature chain. It is well suited to internal enterprise systems, archive systems, approval workflows, medical imaging use cases, or teams that need to embed PDF editing/annotation into ASP.NET. The drawbacks are opaque pricing, no clear statement on whether it is open source, and support commitments that mainly appear to be email and customer-support entry points, with no SLA found. In addition, parts of the technology stack description look dated, so compatibility and performance should be validated through hands-on testing.
The content does not provide information about mainland China access, payment, or localization, so access status is rated as unknown. If procurement is constrained, alternatives to compare include Apryse/PDFTron, Aspose, Syncfusion, GrapeCity Documents, iText, Telerik, and LEADTOOLS.
