OBJ Editor Online

This tool is a browser-based OBJ editor designed for 3D artists, game developers, and pipeline engineers who need to inspect, modify, and export Wavefront OBJ assets without desktop software. It loads OBJ and optional MTL files, preserves materials and groupings, and supports in-browser editing workflows for rapid iteration and asset repair.
Conceptually, the editor builds an in-memory data model of vertices, texture coordinates, normals, and faces. Editing modes include vertex position adjustments, texture coordinate edits, face reindexing, and material reassignment. Advanced features add non-destructive edit history, batch operations, and diff exports. The tool validates indices, ensures compatibility with MTL references, and can recompute normals when missing. It supports copy/paste of coordinates and batch updates across multiple objects.
Who benefits: artists validating asset integrity during reviews, engineers integrating assets into engines, and teams performing quick fixes in the asset pipeline. Unique value comes from no-installation access, direct OBJ/MTL export, and lightweight validation that surfaces common issues early. Use cases include correcting vertex coordinates, swapping textures, merging groups, and converting assets between pipelines; outputs support OBJ/MTL exports and optional JSON descriptors for integrations.
Operational notes: session-based history and patch-like diffs support review workflows. It targets typical asset sizes in small-to-medium projects, using streaming and incremental parsing to reduce memory usage. It does not provide full rendering or server-side processing; it relies on file-based workflows and local tooling compatibility.
