Open .BRD Viewer Online

About This Online .BRD Viewer

This streamlined PCB viewer was built for electronics engineers, freelancers, and fabrication reviewers who need instant visibility into Autodesk Eagle board files without installing heavyweight desktop software. The tool runs entirely in your browser, relying on native Web APIs and a GPU-accelerated Canvas renderer to deliver a responsive preview that mirrors the layers inside your schematic. By minimizing dependencies and optimizing the parsing routine, the viewer reaches a median load time well below 2.5 seconds and avoids layout shifts that can derail Core Web Vitals performance. Designers can quickly validate copper pours, verify footprint orientations, and confirm design rules before fabrication or hand-off.

Unlike common shareware viewers, this experience adds offline support, accessible controls, and workflow accelerators such as instant PNG export and layer-state permalinks. Every interaction is keyboard navigable, and the UI follows an inclusive contrast palette inspired by Kadence theme principles for a modern yet comfortable review session.

How to Use the Viewer

Begin by selecting an Eagle .brd file from your device. The parser runs locally, converts the XML to a structured dataset, and draws key layers on the interactive canvas. Toggle layers with the checkboxes to isolate copper, silk, keep-outs, or custom planes. Use “Fit to View” to reset the zoom if you have been exploring details. The component table updates automatically, giving you ref-des cues, values, packages, and placement layers. When you need visual evidence for design reviews, press “Export PNG” to download a clean preview with your current layer selections, and attach it to your documentation.

The “Export Summary CSV” feature compiles component data, signals, and bounding dimensions into a BOM-friendly spreadsheet. Share the current layer configuration with teammates by copying the permalink; they can paste it into the URL bar to restore the same view before loading their board.

Tips for Faster Reviews

For large multilayer boards, start by disabling mechanical and documentation layers to highlight critical routing. Use the tooltip hints in the layer toggles to understand Eagle’s default numbering before enabling custom stacks. Combining the PNG export with the CSV summary gives remote collaborators both the visuals and metadata they need for asynchronous design reviews. If your board appears zoomed-in or flipped, tap “Fit to View” to normalize the canvas. Keeping filenames concise improves traceability when you manage multiple revisions in a shared folder.

Because all parsing happens offline, you can use the viewer in secure labs or while traveling. Clear cached browser data if you want to remove previously loaded files from memory after a session.
