Liwet Technologies provides a free online Gerber Viewer that lets you quickly preview and inspect your PCB fabrication files directly in your browser. Upload your Gerber and drill files to view copper, solder mask, silkscreen, board outline, and drill layers individually or together without installing dedicated software. Easily show or hide layers, zoom and pan across the PCB, measure dimensions, inspect the board layout, and verify your manufacturing data before sending it for fabrication. You can also save and export your Gerber designs as PDF files for documentation, review, printing, or fabrication reference. The viewer is designed to work best on a PC or desktop computer, providing a larger workspace for comfortable layer management and detailed PCB inspection. A quick Gerber file review can help identify missing layers, incorrect or incomplete drill data, board outline issues, layer alignment problems, and other potential manufacturing errors. Once your files are verified, you can proceed confidently with your PCB fabrication requirements from Liwet Technologies.
