What is a .CDT file?
A CDT file is a CorelDRAW template, a vector graphics file that CorelDRAW opens as a starting point for a new document rather than editing the original. Open it in CorelDRAW (paid), or for free in Inkscape or LibreOffice Draw. Note that newer CorelDRAW versions use .cdrt for templates; older .cdt files may not open in the very latest releases.

Can I open an .AI file without Illustrator?
Yes. Illustrator files saved with "Create PDF Compatible File" (the default since CS) contain a full PDF, which we render with pdf.js. Older PostScript-based AI files are rendered with Ghostscript. Layers and editable paths aren't shown; you get an accurate picture of the artwork.
Why does my EMF or WMF look slightly different?
Windows metafiles are drawn by our own renderer, which handles shapes, lines, fills, text and bitmaps, but not every rarely used GDI feature (clipping regions, raster operations, EMF+ effects). The file details list anything that was skipped.
Is my .CDT file uploaded anywhere?
No. Everything runs as WebAssembly and JavaScript. The first EPS or PS file downloads its renderer (about 16 MB) once; after that it's cached.
Can I convert EPS to PNG or PDF?
Yes. Pick a resolution (up to 600 dpi) and press PNG, or press PDF to get a vector PDF made by Ghostscript.
Does it play Flash (.SWF) files?
Yes, with Ruffle, an open-source Flash emulator. Most animations and many games work; complex ActionScript 3 content may not.
