Edit scanned PDFs, view complex 3D CAD files (STEP, IGES, STL, GLTF), run OCR text recognition, and sign documents directly on your device. Zero cloud dependency, maximum security.
A full suite of professional tools running entirely on your local device hardware.
Edit text within scanned documents directly. Annotate, highlight, redact, add signatures, and draw with complete layout fidelity.
Open and inspect industry-standard 3D formats offline: STEP, IGES, STL, OBJ, GLTF, and more. Zoom, pan, rotate, and inspect parts.
Extract searchable text from photos, screenshots, and scans instantly with on-device Optical Character Recognition.
Combine multiple files or split large documents into custom page ranges. Reorder, rotate, or delete pages on the fly.
Files never leave your device. All operations are run locally without cloud uploads, making it fully compliant with strict data policies.
Export your annotated files or print directly from your device with original names, correct page limits, and zero loss of quality.
Powered by local Open Cascade and WebGL technologies, our 3D engine handles large, complex geometries with ease. Experience full orbital camera controls, section cuts, and wireframe views directly on your screen.
Unlike other PDF tools, this application does not use server endpoints to process, convert, or redact your files. Everything is executed on the local client: OCR, 3D CAD translation, compression, and exporting. Your corporate intellectual property stays exactly where it belongs — in your hands.

Quick answers to common questions about offline PDF editing, local 3D rendering, and data security.
You can view STEP and IGES files offline by downloading the PDF & 3D Enterprise Tools app. The application contains a compiled Open Cascade Technology (OCCT) engine running inside WebAssembly, allowing 3D models to render directly on your mobile GPU without cloud data transfers.
Yes, the application features a built-in offline OCR (Optical Character Recognition) engine that translates image coordinates to editable text locally. You can select, modify, resize, and replace text on scanned documents without sending files to external servers.
Yes. The app is built on an offline-first architecture. All PDF editing, OCR scanning, and 3D CAD modeling are performed entirely within the local sandbox of your device. No document is ever uploaded to a remote server, fully complying with strict GDPR, CCPA, and enterprise confidentiality regulations.
The offline viewer supports STEP (.step, .stp), IGES (.iges, .igs), STL (.stl), OBJ (.obj), GLTF (.gltf), GLB (.glb), PRC (.prc), and U3D (.u3d) formats. It also includes basic support for 2D CAD layouts like DXF, DWG, and Gerber PCB layers.
