Gerbview will visualize your design, on the screen or in hardcopy. No more waiting for photo plots or a prototype circuit board, to see your true design.

GerbView supports both RS-274D and RS-274X Gerber formats, and you can use it to convert your older Gerber files to the new RS-274X extended format. The newer extended Gerber format contains embedded aperture information, and this minimizes the risk for errors during the manufacturing of the PCB.

With GerbView's PDF to CAD capability you can convert your Adobe PDF files back to editable Gerber RS-274X and DXF files.

GerbView can create layered PDF, DXF and DWF files where each loaded Gerber file will correspond to a separate layer in the destination file. Check out our blog to read more about how you can create layered PDF files with GerbView. You may in addition create a multi-page PDF file from all loaded layers, where each layer will be placed on its own page in the output file.
With GerbView you can export individual layers, or the whole workspace, to any of the supported raster formats, which includes TIFF, JPEG, PNG and BMP. The resolution and number of colors used for the conversion can be set by the user.

In GerbView you work with a workspace that can contain one or more files (layers) of any of the supported file formats. The workspace can be saved for later use. The workspace will reference your design files, so only need to reload the workspace to see the whole design. You can set the size of this workspace to one of the preselected paper sizes, or to a custom size.

Use the precise measure tool to verify distances and areas. Check apertures used by tracks and flashes using the query and aperture highlight tools.

Markup elements like text, barcodes, QR-codes, images, arrows, lines, symbols, ellipses and polygons can be added to the workspace, and will be included during conversion and printing.
All types of markup elements, for example text or barcode, may be "burned-in" to become a permanent part of a Gerber layer.

You may print your files using a custom scale, for example 100% for original scale, or using fit to page. The print poster mode, also called tiled pages, can be used to print large designs and drawings on multiple sheets. Header, footer and watermark information can optionally be added to the printed sheets.
