Convertpoly review
A private, free browser converter with broad format support and local processing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Convertpoly is a free, browser-based tool for converting, viewing, compressing and rendering 3D files. It suits designers, developers, technical artists and other users who need private format conversion without uploading models or installing software. The product supports mesh, CAD, animation, game, scanning and point-cloud workflows, while its preview and scene-inspection tools help users review models before downloading converted files.
The free plan includes the complete published feature set: conversion between supported formats, 3D model previews, scene and texture inspection, mesh simplification, Draco geometry compression, texture re-encoding and resizing, and browser-based rendering with lighting and camera presets. Convertpoly reads 75 formats and writes 19, giving it broad input coverage while keeping the output set more focused. Texture and sidecar-file support also make it more suitable for assets that depend on related files rather than a single mesh.
Local browser processing is the product's clearest differentiator. Files stay in the browser instead of being uploaded to a remote server, and users can download converted files without creating an account. The trade-off is that Convertpoly is available only on the web, with browser memory serving as the practical constraint on file size. It also lacks batch conversion and API access, so teams handling repeated automated workflows may need another tool. Choose Convertpoly for private, one-off or interactive 3D conversion and inspection; choose an alternative when server-side processing, automation or broader output coverage is central.
