Our verdict on Simpel3D

Simpel3D is a browser-based converter for makers, engineers, and 3D-printing users. It converts STEP, IGES, STL, OBJ, and 3MF files into STL, OBJ, or 3MF output. Processing runs locally in the browser through WebAssembly, so files are not uploaded to a server. Mesh health checks cover watertight status, dimensions, triangles, and volume, while slicer-ready output supports workflows involving Cura, PrusaSlicer, and Bambu Studio.

Pricing is flexible for occasional and recurring use. The Free plan costs $0 forever, requires no account, includes STL, OBJ, and 3MF output plus Mesh Health Check, and is limited to personal use. Standard costs $6.99 per month or $69 per year, adding a commercial license, batch conversion, and large-file splitting. Pro costs $12.99 per month or $99 per year and adds unlimited conversions and a privacy certificate. A $1.99 one-time Day Pass provides unlimited conversions for 24 hours, commercial use, and no account requirement.

Simpel3D fits users who need a focused conversion step before slicing rather than a broad 3D design environment. Paid plans can batch-convert files, and automatic splitting helps prepare large STEP assemblies as separate parts. The main trade-off is format scope: conversion accepts five formats, but output is restricted to STL, OBJ, and 3MF. Its web-only delivery and 30MB maximum file size also shape the workflow. Choose it for affordable, browser-based 3D-printing conversion; choose an alternative when broader output formats or larger-file handling are essential.
