How we knowQuestions
Are my files uploaded anywhere?
No. Every tool runs inside your browser, so your 3D files, drawings and photos are read and converted on your own device. Nothing is sent to a server, which makes it safe for client CAD files and paid models. (Map to STL is the one tool that downloads map data, and only after you ask it to.)
Is it really free?
Yes. There is no sign-up, no watermark and no file size limit beyond what your device's memory can handle.
Which file types can I open?
3MF (including Bambu Studio and PrusaSlicer projects), STEP and STP, STL, OBJ, GLB and glTF, SVG, G-code (also Prusa .bgcode and Bambu .gcode.3mf), and JPG, PNG or WebP photos for the lithophane maker. Results download as STL, 3MF, OBJ or STEP.
Will the files work in my slicer?
Yes. STL, 3MF and OBJ open in Bambu Studio, PrusaSlicer, OrcaSlicer and UltiMaker Cura. Sizes are kept in millimetres, and 3MF downloads keep separate parts and colours where the tool supports them.
Does it work on a phone or a Mac?
Yes. It runs in any modern browser on Windows, macOS, Linux, Android and iPhone. Very large CAD assemblies are faster on a computer.
