Mac
Open 150+ file formats in one calm window—DWG, STEP, PDF, Word, Excel, RAW, archives, code. Fix text in DWG drawings and export vector PDFs, all on your Mac.
Omia is a universal file viewer designed for macOS. Open, edit and convert CAD drawings, 3D models, documents, images, media, archives, code and data files in one focused window.
CAD DRAWINGS (DWG / DXF)
• Open DWG and DXF drawings offline: zoom, pan and switch layers
• Export vector PDF: one page per sheet frame, whole drawing, or the current view; A4–A0; color or black & white; text stays searchable
• Fix text and numbers right on the drawing: click a label, dimension or title-block field, type, and save as a new DWG. The original file is never overwritten.
3D MODELS
• STEP / STP, STL, OBJ, GLB, glTF, PLY and SketchUp models, converted locally—even very large assemblies
• See overall dimensions and measure the distance between two points
OPEN MORE
View 150+ file extensions, including PDF, Word, Excel, PowerPoint, Markdown, HTML, EPUB, common images and camera RAW files, PSD, audio and video, ZIP/TAR/7Z archives, XMind, and many code and data formats.
MORE THAN A VIEWER
• Edit Markdown, HTML, code and plain text
• Make lightweight edits to Word, Excel and PowerPoint content
• Convert between Markdown, HTML, Word, plain text, PDF, CSV, JSON, PNG, JPEG and more; the saved file opens right away
• Organize recent files with folders, pins and tags
PRIVACY FIRST
File parsing, previewing and editing happen locally on your Mac. Omia does not upload file contents, record file names or paths, or send your files to AI or cloud analysis.
PURCHASE
Pay once to download from the Mac App Store and use the full app. No subscription, in-app purchases, or additional payment after a trial period.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• DWG / DXF to vector PDF: one page per sheet frame (detected automatically), the whole drawing, or the current view; A4–A0; color or black & white. Text in the PDF is searchable.
• Fix text and numbers in DWG / DXF drawings: click any text on the drawing, edit it in place, and save as a new file. The original is not overwritten.
• Chinese text in CAD drawings now uses AutoCAD's proportions, so long notes no longer run into the next column.
• After Save As, the new file opens in Omia automatically.
• STEP models now stand upright (Z axis up).
