Why convert STEP to JPG?

STEP (ISO 10303) is the neutral exchange format for precise 3D CAD models, exported by SolidWorks, Fusion, CATIA, Inventor and most other engineering tools. FreeCAD reads the solid and every edge is projected into a standard isometric view, drawn as dark lines on white so the full wireframe of the part is visible.

JPG output is saved at quality 90 with any transparent areas placed on white, giving a compact image with smooth detail.

Frequently Asked Questions

How do I convert STEP to JPG?expand_more
Drop your STEP file above and press Convert. Our servers load the model in FreeCAD, project its edges into an isometric drawing, place it on a PDF page and render that page as the image you chose. The result is saved as a high-quality JPG, ready to download.
Which view of the model appears in the JPG from a STEP file?expand_more
A standard isometric view, looking down on the model from one corner with the Z axis pointing up, so length, width and height all show in one image.
Are curved surfaces of a STEP model drawn smoothly in the JPG?expand_more
Yes. Each curved edge is traced in short segments sized to the model, about 1/1200 of its overall diagonal, so circles, fillets and holes appear as smooth curves.
What happens when a STEP file fills several JPG pages?expand_more
Each page is rendered at 144 dpi and saved as its own JPG image, named page-1, page-2 and so on, and they download together as one ZIP. A single page downloads as one JPG file.
What quality is the STEP to JPG image saved at?expand_more
Each JPG is saved at quality 90, a high setting that keeps text and fine lines clear while the file stays compact. Transparent areas are filled with white.
Is my .step file kept private?expand_more
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.
