Eagle PCB Viewer

The Eagle PCB Viewer processes Eagle design files (.brd, .sch) or zipped project archives to produce a high-contrast, interactive preview of boards and schematics. It analyzes the file structure to extract components, nets, layers, pads, and drill data, then renders a faithful visual representation that scales to large designs without CAD software. It operates entirely in the browser, preserving data privacy for sensitive boards. The tool supports metric and imperial units, and standard PCB layer conventions, enabling engineers, students, and hobbyists to understand layout intent, verify critical connections, and compare revisions across versions.
The viewer maps each design element to a display layer and color, composes a unified preview with consistent coordinate transforms, and provides deterministic rendering so identical files produce identical previews. Core features include file integrity checks, support for single-file and multi-file projects, and export-ready previews. Optional features extend to netlist extraction for quick checks and a BOM summary from the schematic to aid documentation. Use cases cover board verification, schematic cross-checks, and design walkthroughs for teams lacking full CAD licenses.
