CDR Viewer for Android & Online - Open CorelDRAW Files

CDR is the native format of CorelDRAW, and few other programs read it. Logos, signage, banners and print layouts are delivered in CDR files every day, so people regularly receive artwork they cannot open, especially on a phone.

GroupDocs.Viewer Cloud renders CDR artwork through a REST API and sends back PNG, JPG, PDF or HTML pages for an Android app to display. The Android SDK for Java, available from Maven or Gradle, reduces the integration to a few lines, and code samples show the full request cycle.

Vector artwork is often examined closely, so the rendered view supports zoom, page navigation and thumbnails; multi-page CDR documents can be rendered in full or as selected pages. The same API accepts more than 180 formats, so other design and document files follow one code path.

No installation is needed for a single file: the free online GroupDocs.Viewer app opens CDR artwork in the browser, which answers the common request for a CDR viewer online. Developers can evaluate the service on a free trial and issue test calls from the API Explorer.
