I have received some emails with recurring questions and will list answers here.
Convert shapes from PDF documents into Keynote and modify them
Adobe Illustrator can either directly open PDF files, or content selected from PDF documents can be inserted as shapes using copy&paste. AI2Key can then convert the shapes to Keynote.
Convert Illustrator shapes to Apple Pages or Numbers
Shapes in Keynote, Pages, and Numbers are compatible. Once AI2Key has converted Illustrator files to a Keynote document, all embedded shapes can simply by copied to Pages or Numbers using copy&paste.
Convert Illustrator documents to Powerpoint
Copy&paste from Illustrator to Powerpoint (Paste special > Enhanced Metafile) and consequent ungrouping should do the trick.
I don't have/use Illustrator, but want to import my documents as vectors into Keynote.
Export your document as an SVG file and use SVG2Keynote to convert it to Keynote shapes.
