What is a .GBR file?
GBR is a Gerber file describing one layer of a printed circuit board for manufacture.
- Did you know
- Gerber, the industry standard for sending PCB designs to fabs, dates from the 1980s.
- The format is named after Joseph Gerber, whose numerically controlled photoplotter exposed PCB artwork through shaped apertures.
- The format is now maintained by the Belgian company Ucamco, which bought Gerber’s PCB division.
- What Analyser reads
- Open scientific, medical and engineering files: DICOM scans, NIfTI brain volumes, Garmin FIT/TCX activities, FITS astronomy frames, FASTA/FASTQ sequences, chemistry structures (MOL/SDF/MOL2/CIF/XYZ), Gerber/Excellon PCB data, SPICE netlists, EDF/BDF biosignals, JCAMP-DX spectra, SPSS/Stata/SAS datasets and VTK/ParaView meshes - metadata extracted entirely in-browser.
- Depth of analysis
- .GBR is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.

- Drag a .GBR file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
