Corel Presentation Exchange (CMX) is the vector metafile Corel defined for moving drawings between CorelDRAW, Corel Presentation, the WordPerfect graphics editor and other programs. Corel published its layout, so clip-art collections, converters such as UniConvertor and many older graphics programs write it too. CorelDRAW can also save a drawing as CMX under a .cdr name; the viewer recognises those files by their content.
A CMX file is a RIFF file of form CMX1: one or more pages of drawing instructions, with tables of the colours, pens, line styles and dash patterns the instructions point to. Files come with 16-bit or 32-bit coordinates, in the little-endian RIFF layout or the big-endian RIFX layout. This viewer reads all four variants with its own reader, in your browser.
Every page is drawn as vector shapes at its real size in millimetres. The drawing exports as SVG, PDF, DXF, PNG or a self-contained HTML page. CorelDRAW’s own drawings open in the CDR viewer.
Who Uses Corel Presentation Exchange (CMX) Files?
Sign makers, print shops and engravers who receive clip art and logos as CMX, people going through old clip-art CDs and Corel Presentation or WordPerfect graphics, and anyone handed a .cmx without CorelDRAW installed, on a Mac, a Chromebook, Windows or a phone.
Common Use Cases
- See a .cmx clip-art image or logo without CorelDRAW
- Turn a CMX drawing into an SVG or a PDF at its real size
- Get the outlines into CAD or a laser cutter as DXF
- Open a .cdr file that CorelDRAW saved as CMX
- Look through every page of a multi-page CMX file
- Save a PNG or JPG of the artwork for a web page or an email
Features
All Four CMX Variants
16-bit and 32-bit coordinate files, in the little-endian RIFF and big-endian RIFX layouts.
Every Page
Each page is drawn at its own size, one below the other.
Shapes and Curves
Bézier curves, rectangles with rounded corners, ellipses, arcs and pie slices.
Fills and Outlines
Uniform fills and linear and radial fountain fills; outlines with their pen width, colour, caps, joins and dashes.
Layers and Groups
The drawing’s layers appear in the layer panel, where you can hide them.
Colour Models
RGB, CMYK, CMY, HSB, HLS, grayscale, black-and-white, YIQ and Lab colours, converted for the screen.
Its Real Size
Pages are drawn in millimetres, so exports keep the size of the artwork.
CMX Saved as .cdr
A CMX file saved with a .cdr name is recognised by its content and opens.
Export to SVG, PDF, DXF, PNG, JPG, HTML
Save the drawing as a vector file, a CAD drawing, an image, or one web page that opens offline.
No CorelDRAW Needed
An in-house reader that runs in your browser. Nothing to install.
Nothing Is Uploaded
The file is read and drawn entirely in your browser. No account, no upload, no copy of your file on a server.
Compatibility & Format Notes
The viewer reads CMX files with 16-bit and 32-bit coordinates, in both the little-endian (RIFF) and big-endian (RIFX) layouts, from CorelDRAW, Corel Presentation, Corel WordPerfect graphics, clip-art collections and converters. A CMX file saved with a .cdr name opens as CMX.
It draws curves (Bézier paths), rectangles with rounded corners, ellipses, arcs and pie slices; uniform fills and linear and radial fountain fills, with two-colour pattern fills shown as a flat tint and other pattern, bitmap, texture and PostScript fills as a light tint; outlines with their pen width, colour, caps, joins and dashes; groups, global transforms and glass-lens transparency. Layers become layers in the layer panel, and the pages are laid out one below the other. Colours in RGB, CMYK, CMY, HSB, HLS, grayscale, black-and-white, YIQ and Lab are converted for the screen. Pantone spot colours carry no palette in the file, so they show as a grey of their tint.
Text objects, placed bitmaps, clipping regions and arrowheads are left out. Nothing is sent to a server.

Frequently Asked Questions
▶How do I open a CMX file without CorelDRAW?
Drop it on this page. The viewer reads the drawing in your browser and shows every page, on Windows, a Mac, a Chromebook, Linux or a phone alike. From the Export menu you can save it as SVG, PDF, DXF, PNG or JPG.
▶My file is named .cdr but it is a CMX file. Will it open?
Yes. The viewer looks at the content of the file, so a CMX drawing saved with a .cdr name opens here as CMX. Real CorelDRAW drawings open in the CDR viewer.
▶Why is the text missing from my drawing?
The viewer does not read the text objects of a CMX file, and placed bitmaps are left out too. If the text matters, convert it to curves in CorelDRAW before saving the CMX, or export the drawing as PDF or SVG and open that file.
▶Why does a colour look grey?
Pantone and other spot colours are stored in a CMX file by name and tint, without the colour itself, so the viewer draws them as a grey of their tint.
▶Will the exported SVG or PDF be the right size?
Yes. The pages are drawn at their size in millimetres, so the SVG export carries that size and the vector PDF export draws the artwork at 1:1.
▶Is this CMX viewer really free?
Yes, completely free. No signup, no watermarks, no file size limits on the viewer (the optional share-link feature has a 100 MB upload cap). Built by Innerscene as a tool for architects, engineers, and designers.
▶Are my files uploaded to a server?
No. All parsing, rendering, and conversion runs in your browser: nothing is uploaded, stored, or transmitted by default. The Share button is the only feature that uploads a file, and only when you explicitly click it.
▶Can I convert to another format?
Yes, to vector and image formats. Click Export in the toolbar to save the drawing as SVG (at its real size), PDF (a vector page or a snapshot of the view), DXF, a self-contained HTML page, or a PNG or JPG image. DWG is also offered: that one is converted on our server from the DXF the viewer writes. The viewer does not write .cmx.
▶Can I embed this viewer on my own site?
Yes. Click Embed in the toolbar to generate a one-line <iframe> snippet you can paste into any HTML page. You can choose whether the embed shows the viewer’s toolbar.
