Why convert DGN to HEIC?
DGN is the native drawing format of Bentley MicroStation, widely used for roads, rail, utilities and other infrastructure design. The design's lines, arcs and shapes are drawn on a white background with the longest side at 2400 pixels.
HEIC uses High Efficiency Image Coding, the format iPhones and iPads save photos in, so the image is compact while staying sharp.
Frequently Asked Questions
How do I convert DGN to HEIC?
Drop your DGN file above and press Convert. Our servers translate the DGN into DXF with GDAL, draw its linework with the longest side at 2400 pixels, and save that picture as the image you chose. The result is saved as a HEIC image, ready to download.
What happens to DGN elements on the way to HEIC?
GDAL's DGN driver reads the design elements and writes them as DXF entities, which are then drawn as lines, arcs and shapes in the image.
Are the levels of a DGN design drawn together in the HEIC?
Yes. Elements from every level of the design are written into one DXF and drawn together, so the whole design appears in a single image.
How big is the HEIC image from a DGN file?
The drawing is scaled so its longest side is 2,400 pixels, keeping its proportions.
How compact is the HEIC made from a DGN file?
HEIC uses High Efficiency Image Coding, which typically needs about half the space of a JPG of similar quality, so even detailed pages stay small.
Is my .dgn file kept private?
Your file is uploaded over an encrypted connection, converted on our servers and deleted automatically within 24 hours. We never read, share or keep your files, and no account is needed.
