- The layer slider • Build it up, or see one layer alone
- Every feature in its color • Hide travel, infill or supports
- Inspect • Print time, filament and the layer you click

About BGCODE
Prusa Research made binary G-code in 2023, with PrusaSlicer 2.7, for its MK4, MINI and XL printers. It holds the same moves as G-code in blocks a printer reads quickly, and its print time, filament and pictures in blocks of their own, so the printer's screen shows them at once.
Each block is packed: the moves with MeatPack, which fits two characters in a byte, and Heatshrink, the metadata with Deflate. A BGCODE takes a fraction of the room its G-code would.
Filepeek unpacks it in your browser and draws each extrusion as a bead as wide and as tall as PrusaSlicer made it, each feature in its color. Drag the slider to see the print as far as any layer, press Play to watch it build up, or show one layer alone, with the print time, the filament and the slicer's picture in Inspect.

Questions
How do I open a BGCODE file?
Drop it on this page or press Peek a BGCODE. It's unpacked and opens in 3D, every feature in its color, with nothing to install.
Can I see it layer by layer?
Yes. Drag the slider under the print to show it as far as any layer, press Play to watch it build up, or show one layer alone.
Does it show the print time and the filament?
Yes. Inspect shows the time and the filament PrusaSlicer worked out, and the picture it saved for the printer's screen.
Is my file uploaded?
No. The file opens inside your browser and never leaves your device.
