OmniView 3D doesn't open .pdf files directly — but it opens the STEP, GLB and FBX source files behind 3D PDFs. Better interactivity, no Adobe dependency, works on any device.
Free plan · No credit card · STEP, GLB, FBX supported
3D PDFs were designed for Adobe Reader. In 2026, that means blocked files for most of your recipients.
3D PDFs only open in Adobe Reader with the 3D plugin — not supported on Mac, Linux or modern browsers.
Adobe Reader 3D requires Windows desktop. No iOS, no Android, no tablet.
Your client needs to have the exact same Adobe version with the 3D plugin activated. This rarely works in practice.
Open your STEP/GLB file — free, no Adobe

Request STEP, GLB or FBX from your supplier — the source of the 3D PDF.
Drag and drop your file. Conversion is automatic, in the browser, under 60 seconds.
A private URL is generated. Your recipient opens it in any browser — no Adobe, no install.
Stop sending 3D PDFs your prospects can't open. Share a STEP or GLB link on OmniView 3D — they open it on any device in 2 clicks.
Receive a 3D PDF from a supplier? Ask for the STEP instead. Upload it to OmniView 3D and review the part with your team without Adobe.
Access 3D spare part models from a shareable link on any tablet or phone — no Adobe plugin, no VPN to the CAD server.
OmniView 3D does not open .pdf files directly. It opens the source formats that are used to generate 3D PDFs: STEP, GLB, FBX, OBJ, STL, IGES and more (13+ formats). The result is a richer, more interactive experience — with rotation, zoom, annotations, shareable links and iFrame embed.
Yes, partially. While OmniView 3D does not open .pdf files directly, it reads the source format (STEP, GLB, FBX) that was used to generate the 3D PDF. Ask your supplier for the native CAD file and open it on OmniView 3D in 60 seconds.
A 3D PDF viewer lets you rotate, zoom and inspect a 3D model embedded in a PDF file. Adobe Reader 3D is the most common, but it requires Windows and specific plugin versions. OmniView 3D is a browser-based alternative that supports the source formats behind 3D PDFs (STEP, GLB, FBX).
For browser-based viewing without installation: OmniView 3D (STEP, GLB, FBX), Autodesk Viewer (many formats), or Tetra4D. OmniView 3D is the best choice for sharing interactive links with clients who have no software installed.
Not directly. A 3D PDF embeds a mesh representation, not the original parametric geometry. Instead, ask your supplier to share the native STEP or GLB file — then open it on OmniView 3D for a better interactive experience.
