Import File Formats

Different Formats, One Comparison Baseline

Load standard Gerber data directly without conversion,
and cross-compare bidirectionally with PCB and ODB++ formats.

  • Gerber RS-274X
  • Gerber (.gbr)
  • Gerber (.pho)

info Bidirectional cross-comparison: compare Gerber, PCB, and ODB++ in either direction.

Compare Only the
Layers You Need

Compare the entire design at once, or select specific layers
to focus your review on the changes that matter.

  • Layer-Specific Comparison

    Select only the layers you need to focus your change analysis.

  • All-Layer Comparison

    Compare every layer at once so no change is missed.

  • Manufacturing Geometry Check

    Catch even the smallest geometry differences in production data.

See What Changed
at a Glance

Overlay two Gerber datasets to compare geometry differences visually,
down to the finest changes in patterns, pads, and holes.

  • Image-Based Geometry Comparison

    Overlay the two datasets to see how line widths, spacing, and pad shapes changed at a glance.

  • Automatic Difference Highlight

    Highlights changed areas in color so you can confirm only intended changes were applied.

  • View-Matching Navigation

    Jump straight to each difference to review only the changed spots efficiently.

Turn Results Straight Into
Review Documents

Export analyzed differences to Excel format
for work instructions, design reviews, and change-history management.

  • Export Results to Excel

    Save the difference list as a document to use as review material.

  • Work Instruction Creation

    Organize manufacturing and revision instructions with ease.

  • Change History Management

    Keep a structured record of changes across versions.

Use Cases
