Layer inspector
Select one layer with “View only”, or tick several to overlay them. All layers share the same coordinates and are viewed from the top, including bottom copper.
Only successfully parsed layers are listed. Compare the list with the archive files below to confirm that all expected layers are present.
Files in your Gerber archive
What should your Gerber ZIP contain?
Export Gerber RS-274X or Gerber X2 files for each copper layer, solder mask and silkscreen, plus a clearly named board outline and Excellon drill files. Common extensions include .GBR, .GTL, .GBL, .GTS, .GBS, .GTO, .GBO, .GKO, .GML, .DRL and .XLN.
View one PCB design per archive. Dimensions and layer detection are references; this preview does not replace a manufacturing review or a DRC check. Put special stackup, impedance and production requirements in PCB Remark when ordering.
