Why convert GBR to WebP?
GBR is the Extended Gerber (RS-274X) format that PCB design tools export for each board layer, such as copper, solder mask, silkscreen and board outline. The layer's pads, tracks, fills and outlines are drawn in teal on a white background at 300 dpi, with anti-aliased edges.
WebP stores the rendered image in a modern, efficient format, so the file is noticeably smaller than an equivalent PNG or JPG.
Frequently Asked Questions
How do I convert GBR to WebP?
Drop your GBR file above and press Convert. Our servers render the Gerber layer with gerbv at 300 dpi, producing an anti-aliased PNG that is then encoded in the format you chose. The result is saved as a compact WebP image, ready to download.
What colours does the GBR layer use in the WebP?
The layer's artwork is drawn in teal (#007F73) on a plain white background, which keeps pads, tracks and copper pours clearly visible.
At what resolution is the GBR layer drawn for the WebP?
gerbv, the open-source Gerber viewer from the gEDA project, draws the layer at 300 dots per inch with anti-aliasing, so every inch of board becomes 300 pixels before the WebP is encoded.
How big is the WebP image from a GBR file?
The Gerber layer is drawn at 300 dpi, so the board's dimensions translate directly into pixels.
How much smaller is the WebP from a GBR file?
WebP typically produces files around a quarter to a third smaller than JPG at similar visual quality, and far smaller than PNG, while text and lines stay clear.
Is my .gbr file kept private?
Your file is uploaded over an encrypted connection, converted on our servers and deleted automatically within 24 hours. We never read, share or keep your files, and no account is needed.
