Technical note

How PSD and STP differ in practice

PSD is made of pixels, so the conversion works in two steps: the image is first traced into vector outlines, and those outlines are then extruded to the height you set. The result is real geometry rather than a picture wrapped in a 3D file. Outline tracing is the mode to use here, because it returns closed shapes, and only a closed shape has an area to lift. How good the result is depends almost entirely on the PSD going in. Clean line art, a logo or a drawing scanned at 300 dpi or more traces into geometry you can work with. A photograph does not: continuous tone has no contours to follow, so tracing it produces thousands of tiny shapes and a file nobody can edit. Scan or export at the highest resolution available, and prefer a lossless original, because compression artefacts along an edge become ripples in the traced path.

3D Workflow

From picture to 3D model

Need a 3D STP from a flat PSD image? reaConverter vectorizes it, extrudes the shapes to the height you set, and works through a whole folder at once.

  • Each image is vectorized first, then extruded to the height you set in millimetres
  • Works best with logos, signs and line art: a photo has no clean outlines to follow
  • Tune the tracing precision so the edges follow the original

I'm not a Photoshop user, but clients send me PSD files all the time. reaConverter converts them to PNG or JPG in seconds – I can finally preview their designs without buying Adobe. The batch mode handles dozens of files at once. A real time‑saver.

I'm a freelance illustrator, and I send PSDs to clients for feedback. But they can't always open them. reaConverter converts my PSDs to PDF with embedded layers, so they can view and comment without Photoshop. It's made client collaboration so much smoother.

I had a huge PSD archive from an old project that I needed to convert to TIFF for printing. reaConverter preserved every layer and adjustment – the output was identical to the original. I've tried other converters, but they always flatten or lose quality. This one is the real deal.

FAQ

PSD to STP Conversion

What are PSD files?

PSD is the default format for handling images using Adobe Photoshop and it represents a layered image file. PSDs allow later editing of available layers, including transparency, masks, alpha channels and texts, among others. After applying all desired editing, PSD files can be saved in Photoshop under more easily recognizable formats, such as JPEG or PNG, which are also smaller in size but flatten the image and hence do not allow later editing of layers.

What are STP files?

STP is a file format used by popular CAD software. STP contains 3-dimensional data saved in the Standard for the Exchange of Product Data (STEP, ISO 10303) file format.
