Files live on encrypted S3 storage for 2 hours, then are permanently purged. We never log file contents.
Free for up to 10 conversions per hour with no account. Pro unlocks larger files and priority queue.
Drop a STL file from your device, or paste a public URL pointing to the STL you want to convert.
The output is pre-set to PLY. You can adjust quality or bitrate in the advanced options if you need a smaller file.
Click Convert. Our cloud workers fetch the STL, scan it for malware, and run the STL → PLY pipeline.
A one-time pre-signed link appears as soon as the PLY is ready. The file is automatically deleted from our storage 2 hours later.
