Materials, textures, and complete outputs
Local 3D Model Converter retains supported material colors, UVs, and image textures when converting existing mesh models. STL does not carry standard materials or textures. Keep referenced MTL and image files accessible; Folder Scan can grant access to their folder. OBJ, FBX, USDA, and USDC may use companion resources, which are included in ZIP sharing. Custom shaders and some mappings may be simplified; check conversion warnings and the result in your destination app. Animation, skinning, cameras, lights, CAD solids, mesh repair, and image-to-3D are outside this conversion profile.
CORE FEATURES
DESIGNED FOR
QUESTIONS
Which formats can I convert?
Import STL, OBJ, GLB/glTF, FBX, 3MF, USDA, USDC, and USDZ. Export STL, OBJ, GLB, FBX, 3MF, USDA, USDC, and USDZ. Supported materials, UVs, and textures are converted; STL is geometry-only. Unsupported shader channels are reported. Animation, skinning, cameras, and lights are not preserved.
What can I use for free?
All supported input formats are available without a format purchase. Single-file conversion to STL or OBJ is free. GLB and other paid export formats, batch conversion, and folder conversion have separate lifetime purchases; an active Pro subscription includes all three. Advanced batch or folder output requires both format and workflow access.
Does folder monitoring work on iPhone or iPad?
iPhone, iPad, and Mac support folder conversion. Continuous folder monitoring is Mac-only, starts when you explicitly enable it, and requires the app to remain running. It does not continue after the app quits.
Are materials and textures retained?
Supported material colors, UVs, and image textures are retained when the target format can represent them. Keep referenced resources accessible, or use Folder Scan to select their folder. Share multi-file outputs as the prepared ZIP. STL cannot retain appearance; custom shaders and some mappings may be simplified. This app does not import STEP/IGES, repair meshes, or generate models from photos.
Which devices are supported?
iPhone and iPad require iOS / iPadOS 26 or later. Mac requires macOS 26 or later and Apple silicon. There is no visionOS version.
Are my models uploaded?
Conversion and preview run locally with no account, tracking, or model uploads to the developer. Cloud-backed input files, App Store purchases and restoration, and sharing to online destinations may require a connection.
