DWG Viewer, DWG Reader & PDF to DWG Converter.
Open any DWG or DXF drawing and see every line, layer, and sheet exactly as it was saved — on your iPhone, iPad, or Mac. Turn a PDF plan or a photo of a paper drawing into a real CAD drawing, measure and mark it up, make the edit, and send it on as DWG, DXF, PDF, or an image.

DWG is the file format behind almost every architectural plan, engineering drawing, and site layout you will ever be sent. It is also the file that arrives in an email on a phone or a Mac with nothing on it that can open it. You can see the name of the drawing and nothing else — so the question about a dimension, a door swing, or a revision cloud waits until you are back at a desk with CAD software.
DWG Viewer is the DWG file viewer for that moment. Open the file and every line, arc, hatch, block, and note is drawn the way the original CAD software saved it, from the oldest AutoCAD releases to the newest. DXF drawings open the same way, so it works as a DXF file reader too. Every sheet and layout in the set is there, and smooth zoom takes you from the whole plan down to the smallest dimension text without the drawing breaking up.
A busy drawing becomes readable when you control what is on it. Show, hide, or isolate any layer with a tap to strip a plan back to the walls, the structure, or the services. Tap any line, block, or wall to see which layer it lives on and what its properties are. And when the drawing carries a 3D model, it opens in a full interactive 3D view you can orbit, pan, and zoom, in shaded, wireframe, or x-ray display — a 3D DWG viewer in the same app as the 2D sheets.
Not every drawing arrives as a DWG. Some arrive as a PDF, and some arrive as a photo of a paper plan pinned to a wall. DWG Viewer turns both into real drawings. A PDF plan becomes a drawing made of true lines, arcs, and text rather than a flat picture — PDF to DWG, PDF to CAD, on the device. A photo or scan of a paper drawing becomes a drawing too, with its text recognised, so an image to DWG conversion gives you something you can measure and edit. Type one length you know, and the whole drawing is set to the right scale.
Then the drawing does work. Measure distances, paths, areas, and angles, with snapping to endpoints, midpoints, centers, and intersections so a measurement lands where it should. Mark it up with revision clouds, arrows, lines, shapes, and notes in the color you choose. Use it as a DWG editor when a change cannot wait: draw, move, copy, rotate, scale, mirror, and delete, with exact typed lengths and coordinates. Drop in doors, windows, furniture, fixtures, trees, vehicles, and steel profiles from a built-in library of real-world blocks.
When it is time to hand the drawing on, save it as a DWG or a DXF for the CAD desk, or convert DWG to PDF, PNG, JPG, or SVG for everyone else. Find any word across every sheet in seconds when you are hunting for a room name or a part number. Files open straight from the Files app, Mail, AirDrop, or any app's share sheet, there is no account to create, and every drawing stays on your device.
Convert DWG to PDF, PDF to DWG, and photos to CAD.
The drawing you have is rarely in the format the next person needs. Convert it on your iPhone, iPad, or Mac without uploading it anywhere.
DWG → PDF
Convert a DWG file to PDF so a client, contractor, or planner can open the drawing without CAD software.
PDF → DWG
Turn a PDF plan into a real drawing with true lines, arcs, and text — ready to measure, edit, and save as DWG.
Photo → DWG
Turn a JPG or PNG photo or scan of a paper drawing into a CAD drawing, with its text recognised.
DWG ↔ DXF
Save a drawing as DWG or DXF, so the file opens in whichever CAD program is on the other end.
DWG → PNG, JPG, SVG
Export the drawing as an image for a message or a report, or as SVG for a website or a design tool.
Set the scale
Type one length you know and the converted drawing is scaled to real-world size.
How to open a DWG file on iPhone, iPad, or Mac.
Open the DWG file
Tap a .dwg or .dxf from the Files app, Mail, AirDrop, or any app's share sheet — or tap Open File inside DWG Viewer. A PDF or a photo of a drawing opens the same way.
Read the drawing
Zoom from the full plan to the smallest note, step through every sheet and layout, show or isolate layers, and tap any object for its layer and properties.
Measure, mark up, and edit
Measure distances, areas, and angles with snaps, add clouds, arrows, and notes, and make the change — move, copy, rotate, scale, or insert a block from the library.
Save and share
Save as DWG or DXF, or export to PDF, PNG, JPG, or SVG, then share it or save it back to Files.
DWG and DXF in, every format you need out.
The CAD drawing format for plans, sections, details, and models — opened from the earliest releases to the newest, and saved back as DWG.
The drawing exchange format, opened with its layers and layouts and saved back as DXF, so DWG to DXF and DXF to DWG both work.
A PDF plan turned into a real drawing, and any drawing exported as a PDF anyone can open.
A photo or scan of a paper drawing turned into CAD, and any drawing saved as an image.
Export a drawing as SVG for a website, a presentation, or a design tool.
A DWG viewer, converter, and editor in one app.
Every DWG and DXF
Drawings from the earliest CAD releases to the newest open with every line, arc, hatch, block, and note where it belongs.
Sheets and Layouts
Move through every sheet and layout in the drawing set, with smooth zoom down to the smallest dimension.
Layers You Control
Show, hide, or isolate any layer with a tap, so a crowded plan comes down to exactly what you need to read.
Object Properties
Tap any line, block, or wall to see which layer it sits on and the properties it carries.
3D DWG Viewer
Open the 3D model inside a drawing and orbit, pan, and zoom around it, in shaded, wireframe, or x-ray view.
PDF to DWG
Convert a PDF plan into a true CAD drawing made of lines, arcs, and text, instead of a picture you cannot measure.
Photo and Scan to DWG
Photograph a paper drawing and turn it into a CAD drawing, with the text on it recognised.

Frequently asked questions about DWG files.
What is a DWG file?
DWG is the native file format of AutoCAD and many other CAD programs. A DWG file holds a drawing — lines, arcs, text, dimensions, blocks, layers, layouts, and sometimes a 3D model — and it is the standard way architects and engineers save and share drawings.
How do I open a DWG file on iPhone or iPad?
Open it with DWG Viewer from the Files app, Mail, AirDrop, or any app's share sheet. The drawing opens with every sheet, layout, and layer, and you can zoom down to the smallest detail.
Is there a DWG viewer for Mac?
Yes. DWG Viewer runs on Mac as well as iPhone and iPad, so the same CAD viewer is on your desk and in your pocket.
What program opens DWG files without AutoCAD?
DWG Viewer opens DWG and DXF drawings directly on iPhone, iPad, and Mac, so you can read, measure, and convert a drawing without installing CAD software on a computer.
Can I convert DWG to PDF?
Yes. Export any drawing as a PDF that anyone can open, or as a PNG, JPG, or SVG image.
Can I convert PDF to DWG?
Yes. A PDF plan becomes a real drawing made of lines, arcs, and text — not a flat picture — which you can measure, edit, and save as DWG or DXF.
Can I convert a JPG or photo to DWG?
Yes. A photo or scan of a paper drawing becomes a CAD drawing with its text recognised. Type one known length to set the scale.
Can I convert DWG to DXF, or DXF to DWG?
Yes. Open either format and save the drawing as DWG or DXF.
Can I edit a DWG file?
Yes. Draw, move, copy, rotate, scale, mirror, and delete, with exact typed lengths and coordinates, then save the result as DWG or DXF.
Can I measure on a DWG drawing?
Yes. Measure distances, paths, areas, and angles, with snapping to endpoints, midpoints, centers, and intersections.
Can I view a 3D DWG?
Yes. A 3D model inside a drawing opens in an interactive view you can orbit, pan, and zoom, in shaded, wireframe, or x-ray display.
Does it include CAD blocks?
Yes. A built-in library of real-world blocks — doors, windows, furniture, fixtures, trees, vehicles, and steel profiles — can be inserted straight into a drawing.
Can I turn layers on and off?
Yes. Show, hide, or isolate any layer with a tap, and tap any object to see which layer it belongs to.
Can I search for text in a drawing?
Yes. Find any word across every sheet in seconds — a room name, a tag, or a part number.
Should I use a DWG viewer online instead?
Online DWG viewers and online PDF to DWG converters ask you to upload the drawing to someone else's server first. DWG Viewer opens and converts the file on your own device, so a client's plans never leave it.
Do I need an account?
No. There is no account and no login. Open a drawing and start working.
