TotalViewer

Supported file formats and viewers

Choose a file viewer and check supported inputs, usage and limits before opening your file.

Open up to three files per day in the same browser without signing in. The count resets at midnight Korea time. Files are processed on your device. File, geometry and memory limits apply to both Free and Pro.

DXF Viewer

View supported 2D CAD geometry, text and layers with the TotalViewer DXF viewer. External references, fonts and unsupported entities can look different from the original CAD application.

  • DXF Viewer

STL, OBJ and PLY Viewer

DWG Viewer

Try the TotalViewer DWG viewer without installing CAD software. The browser converts supported DWG objects to DXF for a read-only preview. Some versions, fonts, external references and 3D objects may be missing; verify the result in the original CAD application.

  • DWG Viewer

STEP and STP Viewer

Open STEP or STP files in the browser, select parts, and rotate or zoom the converted model. This STEP viewer produces an approximate mesh; manufacturing dimensions should be checked in the original CAD application.

  • STEP Viewer
  • STP Viewer

IGES and IGS Viewer

View supported IGES or IGS surfaces as a converted 3D mesh. Rotate and inspect parts in TotalViewer. Incomplete surfaces can fail to convert or appear only partially.

  • IGES Viewer
  • IGS Viewer

KiCad PCB and Schematic Viewer

Preview a standalone KiCad 6+ KICAD_PCB board or KICAD_SCH schematic in the browser. This KiCad viewer is read-only and does not load external sub-sheets or project libraries, run DRC, or show a 3D PCB.

  • KICAD_PCB Viewer
  • KICAD_SCH Viewer

Excel, CSV and BOM Viewer

Read XLS, XLSX, XLSM or CSV parts lists with the TotalViewer Excel and CSV viewer. Choose sheets and browse saved values. Macros, formulas and external links are not executed; search and cell details are Pro features.

  • EEP Viewer
  • S19 Viewer
  • SREC Viewer
  • SRE Viewer
  • MOT Viewer

BREP and BRP Viewer

Open supported OpenCascade text BREP or BRP geometry as a 3D mesh. Rotate and inspect parts locally. Files without unit information use model-coordinate units; confirm actual dimensions in the original CAD application.

  • BREP Viewer
  • BRP Viewer
