As answered by people managing CloudConvert and StlFixTool.
StlFixTool's answer:
StlFixTool's answer:
Every conversion is verified before you download it. StlFixTool checks the output against the input (volume, bounding dimensions, watertightness) and shows you the result, including any simplification it applied. It doesn't hand you a file and hope. Multi-part assemblies keep each solid's topology separate, so parts don't get fused or broken at their boundaries. You pay per file, with no subscription and no account plan to cancel.
StlFixTool's answer:
If you only need one file converted or repaired, you shouldn't need a monthly plan. StlFixTool charges per file ($2.99–$5.99), shows a 3D preview and a verification report before you pay, and outputs in millimetres. The viewers and the STL editor are free. Uploads are deleted automatically: after 1 hour if unpaid, after 7 days once paid.
StlFixTool's answer:
People who need a 3D file in a different format or a broken mesh fixed, without installing CAD software. That's mostly 3D printing hobbyists and makers turning STEP/3MF/OBJ/GLB files into printable STL, people whose slicer rejects a model as non-manifold or full of holes, and engineers or designers who need an STL turned back into a STEP file for a CAD tool.
StlFixTool's answer:
StlFixTool started as a simple question: why does converting one CAD file mean a subscription or a desktop install? Building it turned out to be harder than it looked. The worst bug was a vertex-welding step that silently merged points across separate solids in an assembly, which broke closed parts without any visible error. That bug is why every conversion now runs an automatic verification check before delivery. The full write-up is on dev.to: "The vertex weld that silently broke every assembly I converted".
