FAQ

common questions

Is the PLY to STL converter free?

Yes. Every conversion on this site is free, with no signup, watermark or file count limit.

Are my files uploaded to a server?

No. Conversion runs entirely in your browser using three.js. Your files never leave your device, so we cannot see them even if we wanted to.

Is there a file size limit for PLY to STL?

There's no hard limit. In practice, file size is bounded by your device's available memory — typically several hundred megabytes work fine on a modern computer.

Does it work offline?

Once this page has loaded, yes. You can disconnect from the internet and the converter will still work. Reloading the page does require connectivity.

Will my PLY file lose quality when converted to STL?

It depends on the formats involved. Converting between lossy formats (JPG, MP3) re-encodes data and slightly reduces quality. Lossless formats (PNG, WAV, FLAC) preserve everything. Pixel dimensions and color depth are preserved for image conversions.
