G-code Thumbnail Studio
Extract the preview images printers show on their screen, or generate a fresh thumbnail from the toolpath and embed it in the G-code.
G-code, gzip, bgcode, and gcode.3mf are supported. Nothing is uploaded.
From file to decision in three steps
No installation. No signup. No waiting for an upload.
Drop a file
Choose a G-code file from your slicer, SD card, or a message from a friend. It opens locally.
Understand it
See the toolpath by layer, check time and material, and catch obvious problems before you print.
Use it
Export a report, convert the format, or take the numbers into your cost calculation.
G-code Thumbnail Studio
Pull the preview image out of a G-code file, or render a clean thumbnail from the toolpath and write it back into the file.
- PNG, JPG, and QOI extraction
- Top and isometric renders
- Prusa, Bambu, and Orca sizes
- Embed without uploading
