Why convert STP to JPG?
STP is the common .stp extension of STEP (ISO 10303), the standard format for exchanging solid 3D models between CAD and manufacturing software. Every edge of the model, front and back, is projected into an isometric view and drawn as dark lines on a white background, giving a clear wireframe of the part.
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 STP to JPG?
Drop your STP file above and press Convert. Our servers open the STP model with FreeCAD, trace every edge into an isometric line drawing, and render it through a PDF page into the image you chose. The result is saved as a high-quality JPG, ready to download.
Are hidden edges of the STP part shown in the JPG?
Yes. The drawing is a see-through wireframe, so edges at the back of the part are drawn along with the visible ones, which reveals holes and pockets on every side.
Does a STP assembly with several bodies come through in the JPG?
Yes. FreeCAD reads the file's complete shape, so every body it contains is drawn together in the same isometric view.
What happens when a STP file fills several JPG pages?
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 STP to JPG image saved at?
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 .stp 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.
