How to Convert STL to PLY Free, Step by Step
Need a PLY from an STL? Here is how to convert STL to PLY, what usually goes wrong, and how to get a file you can use first time.
Why convert STL to PLY?
A PLY is a 3D mesh format from scanning, often with a colour per vertex. Holds scan colour and point clouds.
- 3D scanning.
- Photogrammetry.
Where most converters let you down
Plenty of tools will happily take your STL and give you something back. The trouble is what they give you: many lose units, flip axes or hand you a mesh with holes. You only find out later, when the file will not cut, print, import or open the way you expected.
What you actually want is the model in the format you need, checked before download. That is the standard this STL to PLY converter is built to.
How to convert STL to PLY in 3 steps
- Open the STL to PLY converter and drop in your STL.
- Check the result in the preview and adjust the settings if you need to.
- Download the PLY.
Why Veconvert is the better STL to PLY converter
- See it in 3D. Rotate and inspect before saving.
- Watertight check. Holes are reported.
- No CAD install. Works in the browser.
- Nothing uploaded. Designs stay private.
What happens to your file
An STL is read in your browser, and shown in 3D so you can turn it round.
The conversion runs in your browser, so the file is never uploaded: client work, statements and unreleased designs stay on your computer.
Getting the best PLY: mistakes to avoid
- Check the reported size: STL and OBJ carry no units, so millimetres are assumed.
- For printing, 3MF keeps units and colours that STL drops.
What it costs
Yes, converting is free: the conversion and checking the result cost nothing, and the work runs in your browser, so nothing is uploaded. The side-by-side preview on the converter pages comes with a free account. Saving the finished file is paid: $3.49 for one file ($3.99 for a technical file such as DXF, G-code, STL or embroidery) with no account needed, or included in a plan from $6.99 a month.
You see the result before you spend anything, so you only pay for a file you are happy with.
