Open .cdr drawings, .cdt templates, and .cmx presentation exchange files locally—without uploading your work to a website. WHY THIS APP • No CorelDRAW on your Mac? Preview client CDR files on the go. • Received a .cdr attachment in Mail or Messages? Open it in one tap. • Need a quick look at page count, size, or embedded metadata before you reach a desktop? SUPPORTED FORMATS • .cdr — CorelDRAW drawing • .cdt — CorelDRAW template • .cmx — Corel presentation exchange OPEN FILES YOUR WAY • “Open in…” from Files, Mail, cloud drives, or other apps • Pick a file from the in-app file chooser • Reopen from your recent files list • Documents can open in place when supported by iOS—your originals stay where you saved them VIEW & NAVIGATE • Multi-page documents with a page switcher • Pinch to zoom, drag to pan, double-tap to fit the page • Document sidebar: version, page size, title, author, fonts, and more • Built-in thumbnail preview when the file provides one • Light, dark, and system appearance EXPORT & SHARE • Share or save the current page as SVG, PNG, or PDF • Export all pages to a single PDF • Use the system share sheet to send results to Mail, Files, or other apps BROAD VERSION COVERAGE Designed around the industry-standard libcdr engine with an in-app fallback parser. Typical support spans legacy CDR 7 through modern containers including X4/X5/X6+ ZIP-based files and many X8-era documents. Very new or highly complex files may show partial content; see limitations below. BUILT FOR iOS • Native UI with layouts tuned for phone and tablet • Works offline after the file is on your device • No account required IMPORTANT NOTES • Viewer only: this release focuses on opening, inspecting, and exporting—not desktop-class editing inside CorelDRAW. • Rendering fidelity varies by file version and features (advanced text, some pattern fills, or uncommon effects may appear simplified or as placeholders). • Some X6+ and newer files with external data streams may not render every object until support improves in a future update. • For best text display, fonts used in the design should be installed on your device where possible. PRIVACY Files you open are processed on your device. The app does not require you to upload documents to our servers to view them. LEGAL CorelDRAW® is a registered trademark of Corel Corporation.
