To convert PLY to OBJ, choose your PLY 3D models above, adjust the options if needed and press "Convert to OBJ". The OBJ downloads instantly: free, with no sign-up, and the file never leaves your device.
About the PLY to OBJ Converter
Need to turn a PLY file into OBJ? This free converter changes PLY 3D models into OBJ in a few seconds, right in your browser. People usually convert because PLY is rarely supported outside scanning and research software, while OBJ gives you an OBJ mesh any 3D app imports. OBJ files open in Blender, Maya, 3ds Max, Cinema 4D, Unity, Windows 3D Viewer.
Models are loaded and exported with three.js, the most widely used open-source 3D library for the web. Because everything happens on your own device, your 3D models are never uploaded, stored or seen by anyone else, which makes it safe for client prototypes and unreleased product designs.
What to expect: geometry, normals and UV coordinates are converted, and the model is not rescaled.
How to use the PLY to OBJ Converter
- Click "Choose files" or drag your PLY 3D models onto the box. You can add several at once.
- No settings are needed.
- Press "Convert to OBJ". The conversion runs on your device and shows its progress.
- Download each OBJ file, or use "Download all (ZIP)" when you converted several.
- Open the result in Blender or Maya to check it; your original PLY is never changed.
Tips & benchmarks
- Geometry, normals and UVs are written; materials referenced from a separate .mtl file are not included.
- STL and OBJ files have no units; most slicers assume millimetres, so check the size after importing.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the OBJ to a website or government portal.
Frequently asked questions
How do I convert PLY to OBJ?
Click "Choose files", select your PLY 3D models, adjust the options if you want, and press "Convert to OBJ". The OBJ downloads immediately; with several files you can download everything as one ZIP.
Is this PLY to OBJ converter free and safe?
Yes. It is completely free, with no sign-up, no daily limit and no watermark. The conversion runs inside your browser, so your 3D models never leave your phone or computer and nothing is stored on News Appite's servers.
Are textures and materials kept?
Basic materials and vertex colours are carried over where both formats support them. External texture image files referenced by OBJ or glTF are not bundled unless they are embedded in the source.
Can I convert several PLY files at once?
Yes. Add as many PLY files as you like; they are converted one after another and you can download them individually or together as a ZIP.
Does it work on iPhone, Android and Mac?
Yes. The converter works in any modern browser, including Chrome, Safari, Edge and Firefox, on Android, iPhone, iPad, Windows, macOS and Linux. No app is needed.
What is the difference between PLY and OBJ?
PLY (Polygon File Format (Stanford)) is a 3D scan and point-cloud format best suited to 3D scanning, photogrammetry, point clouds and research datasets. OBJ (Wavefront OBJ) is a text-based 3D mesh best suited to exchanging meshes between Blender, Maya, 3ds Max, ZBrush and game engines.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
How do I convert PLY to OBJ in Python?
Use trimesh: trimesh.load('input.ply').export('output.obj'). If you just need the file, this converter does it in the browser without writing any code.
PLY ko OBJ kaise kare?
Is page par "Choose files" dabaiye, apni PLY file chuniye aur "Convert to OBJ" par click kijiye. OBJ file turant download ho jaati hai. Ye bilkul free hai, sign-up nahi chahiye, aur aapki file kisi server par upload nahi hoti.

What is a PLY file?
PLY was developed at Stanford in the 1990s to store data from 3D scanners. It supports vertex colours and point clouds, which is why photogrammetry apps and LiDAR scanners often export PLY.
What is a OBJ file?
OBJ is a simple text format for 3D geometry developed by Wavefront Technologies. Vertices, normals, texture coordinates and faces are written line by line, so virtually every 3D program can import it.
