Why convert GCODE to BMP?
A GCODE file holds G-code, the plain-text instruction language that CNC mills, routers, laser cutters and 3D printers follow, generated by CAM and slicer software. The XY toolpath is plotted as seen from above: cutting and extrusion moves (G1) appear in teal and rapid travel moves (G0) in light grey, on a white background with a small margin.
BMP stores every pixel uncompressed, so the image is exact and simple to read by any software that handles Windows bitmaps.
Frequently Asked Questions
How do I convert GCODE to BMP?
Drop your GCODE file above and press Convert. Our servers trace every G0 and G1 move in the file, draw the toolpath as a vector image with its longest side at 2400 pixels, then encode it in the format you chose. The result is saved as an uncompressed BMP bitmap, ready to download.
How are rapid and feed moves told apart in the BMP from a GCODE file?
Feed moves (G1), where the tool cuts or the nozzle extrudes, are drawn in teal. Rapid positioning moves (G0) are drawn in light grey, so travel paths stand apart from the working path.
Does the GCODE to BMP converter follow inch units and relative positioning?
Yes. G20 inch and G21 millimetre modes are applied as the file switches between them, and G90 absolute and G91 relative positioning are followed move by move. Comments in brackets or after a semicolon are skipped.
How big is the BMP image from a GCODE file?
The toolpath drawing is scaled so its longest side is 2,400 pixels, keeping the part's proportions.
What kind of BMP does the GCODE converter create?
A standard Windows bitmap with every pixel stored uncompressed, so the image is an exact copy of the rendered result.
Is my .gcode file kept private?
Your file is uploaded over an encrypted connection, converted on our servers and deleted automatically within 24 hours. We never read, share or keep your files, and no account is needed.
