Layer Management

Toggle individual layers on and off, customize colors, and control rendering order. Supports copper, solder mask, silkscreen, paste, and drill layers.

Realistic Rendering

Switch to realistic mode to see your PCB as it will look after manufacturing — complete with solder mask color, surface finish, and silkscreen.

Measurement Tools

Measure distances, inspect pad coordinates, and verify clearances directly on the canvas. Supports metric and imperial units.

Compare Revisions

Side-by-side comparison of two Gerber packages with synchronized pan and zoom. Overlay blink mode and pixel diff highlight every change between revisions.

Auto File Detection

Drag and drop a ZIP or individual files. Gerbtrace automatically classifies Gerber, drill, pick and place, BOM, and PDF files by content analysis.

Multi-Format Support

Import Gerber RS-274X, Excellon drill files, pick and place data, BOM spreadsheets, and PDF documents. All standard PCB manufacturing formats supported.

Draw and Annotate

Draw lines, rectangles, and shapes directly on the PCB canvas. Add visual annotations for team reviews and manufacturing notes.

Board Parameters

Configure board dimensions, layers, base material, laminate, copper thicknesses, surface finish, and soldermask. Parameters feed into cost estimation.
