PCB Gerber Viewer
Drop Gerber (RS-274X) or Excellon drill files and get an interactive whole-board view — each file a layer, auto-classified and color-coded. Zoom, pan, toggle layers, measure in mm/inch and export PNG or SVG.
Processing and data safety
Section titled “Processing and data safety”This tool runs entirely in your browser — your files are never uploaded to a server.
Input and output
Section titled “Input and output”- Formats: Gerber, Excellon, PNG, SVG
- Flow: Gerber + Excellon → multi-layer board view in the browser
How to use
Section titled “How to use”- Drop one or more Gerber (.gbr/.gerber/.art) or drill (.drl/.txt) files — each file becomes a layer and the whole board renders instantly.
- Wheel-zoom (pointer-centered), drag to pan, or hit “Fit view”; toggle layers in the Layers panel.
- Switch to Distance and click two points on the board (more points for a chain) — the length shows in board units (mm; inch boards also show the inch value).
Key details and limits
Section titled “Key details and limits”- Negative-polarity layers render no graphics here and are listed as such in the result.
- Legacy RS-274D Gerber may not render — re-export as RS-274X.
- For quick visual inspection, not manufacturing-grade; no layer editing or manufacturing output.
Common use cases
Section titled “Common use cases”- Drop in a full board set (copper/silk/mask/drill) → layered color rendering
- Hide silk in the layer panel to read copper traces only
