How to convert PLY to STL
Upload or paste a PLY link
Drop a PLY file from your device, or paste a public URL pointing to the PLY you want to convert.
Confirm STL as the output format
The output is pre-set to STL. You can adjust quality or bitrate in the advanced options if you need a smaller file.
Start the conversion
Click Convert. Our cloud workers fetch the PLY, scan it for malware, and run the PLY → STL pipeline.
Download your STL file
A one-time pre-signed link appears as soon as the STL is ready. The file is automatically deleted from our storage 2 hours later.
