Frequently Asked Questions

Is converting STL to IGES free?+
Converting STL to IGES 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 STL to IGES lose quality?+
It depends on the formats involved. If both STL and IGES 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 STL to IGES without uploading my file?+
Absolutely. Filoshi processes everything locally on your computer. Your STL 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 STL to IGES?+
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 STL files to IGES?+
Yes, the Filoshi desktop app supports batch conversion. You can drop an entire folder of STL files, select IGES as the output format, and convert them all at once. Each file gets its own progress bar.
