Convert DGN to IGES
Fast, free, and secure DGN to IGES conversion. No registration required.
Transform your dgn files into iges format with a single click. Every conversion runs in your browser, guaranteeing privacy. The input DGN MicroStation format from Bentley Systems handles infrastructure design, civil engineering and utility mapping, while the output IGES Exchange by NIST/ANSI is built for legacy CAD exchange and older engineering data migration. DGN MicroStation files typically can be quite large, while IGES Exchange output is optimized for lossless storage. Your converted files are ready for immediate use — no post-processing or additional steps required.
When Should You Convert DGN to IGES?
There are strong reasons to convert DGN to IGES:
Editing flexibility: IGES Exchange files can be opened in a wider range of editing software, giving you more options for further modifications.
Collaboration ease: Team members and collaborators are more likely to have software that opens IGES Exchange natively, reducing compatibility friction.
Smaller file size: Efficient compression in IGES Exchange often produces significantly smaller files than DGN MicroStation, saving storage space and bandwidth.
Faster loading: IGES Exchange files decode faster on most systems, reducing wait times when opening or streaming content.
Legacy system support: IGES Exchange is backward-compatible with older systems that may not support newer or proprietary formats like DGN MicroStation.

DGN to IGES Quality Analysis
A/B testing confirms that Xonvert's DGN MicroStation to IGES Exchange output is indistinguishable from reference-quality conversions produced by leading desktop software. The WebAssembly engine uses identical codec libraries. Bentley Systems MicroStation native format ASCII-based format originally developed by NIST and DoD These technical characteristics influence how quality is preserved during conversion. For cad-to-cad conversions, Xonvert applies format-aware algorithms that respect the unique characteristics of both DGN MicroStation and IGES Exchange. Converting within the same category means most properties transfer naturally.
CAD format conversion from DGN MicroStation to IGES Exchange transfers engineering drawings, 2D/3D geometry, layers, and dimension annotations. Precision of measurements and geometric relationships is maintained. This is essential when collaborating with partners who use different CAD software packages.

What You Need to Know About DGN to IGES
Does DGN to IGES conversion work on slow internet?▼
Yes — and even with no internet at all. Once the page loads, conversion is entirely offline. Speed depends on your device's CPU, not your internet connection.
How is Xonvert different from other online converters?▼
Most online converters upload your files to their servers. Xonvert processes everything locally in your browser — your files never leave your device. It's faster, more private, and works offline.
Is there a file size limit?▼
There is no strict file size limit. However, very large files (over 500MB) may be limited by your device's available memory.
What are the advantages of IGES over DGN?▼
IGES Exchange offers early CAD interchange standard with wide legacy support, while DGN MicroStation is known for rich CAD data support for infrastructure and civil engineering. The best choice depends on your specific needs — compatibility, quality, or file size.
How does Xonvert compare to desktop software?▼
Xonvert offers comparable quality to desktop converters with the convenience of browser-based access. No installation, no updates, instant availability.
Is it safe to convert my DGN files here?▼
Absolutely. Your files never leave your device — all processing happens in your browser using WebAssembly technology.
Is there an API for DGN to IGES conversion?▼
Xonvert is a browser-based tool without a server API, since all processing happens client-side. For automated conversion, you can use Xonvert's PRO features or integrate the underlying open-source libraries directly.
