What is STEP?

STEP (Standard for Exchange of Product Data) (.step) - STEP is an ISO standard for CAD data exchange between different engineering software. It preserves precise geometry, tolerances, and manufacturing data.

Common use: Engineering, manufacturing, CAD data exchange between different software

Output Format

What is STL?

Stereolithography (.stl) - STL is the standard file format for 3D printing. It describes the surface geometry of a 3D object using triangular facets.

Common use: 3D printing, rapid prototyping, CNC machining

Frequently Asked Questions

Is converting STEP to STL free?+
Converting STEP to STL requires the Filoshi desktop app, which is a one-time $14.90 purchase. This gives you unlimited conversions across 3,332+ format pairs with no subscription or per-file fees.
Does converting STEP to STL lose quality?+
It depends on the formats involved. If both STEP and STL use lossless compression, no quality is lost. If the conversion involves a lossy format, some quality reduction may occur, but Filoshi uses optimized settings to keep quality loss minimal. The conversion runs entirely on your machine, so there are no server-side compression artifacts.
Can I convert STEP to STL without uploading my file?+
Absolutely. Filoshi processes everything locally on your computer. Your STEP files are never uploaded to any server. The desktop app bundles all conversion engines and works completely offline.
How long does it take to convert STEP to STL?+
Most conversions complete in seconds. Larger files (like high-resolution video) may take a bit longer depending on your computer's hardware. Since Filoshi runs locally, there is no upload or download wait time, which is significantly faster than online converters.
Can I batch convert multiple STEP files to STL?+
Yes, the Filoshi desktop app supports batch conversion. You can drop an entire folder of STEP files, select STL as the output format, and convert them all at once. Each file gets its own progress bar.
