Cardify

Cardify is a browser editor that keeps Markdown as the source and treats the look as a rendering result. Type on the left, watch the card update on the right: headings, lists, quotes and code blocks all come through, screenshots can be pasted or dropped straight in, and styled HTML copied from a web page turns back into Markdown instead of a tangle of tags. A 2000-plus emoji picker covers the small icons.

Thirty-plus themes are separate layouts, not one card with a new accent colour - magazine type with an oversized headline, notebook paper, glassmorphism, handwritten stationery, watercolour, neon - and every theme renders your current content at the same time, so picking a style is a glance rather than a round trip through export. Sizes are pre-set for real posts: Instagram 4:5, TikTok 9:16, mobile poster, square and A4 for print.

Export gives you PNG, SVG or PDF, and batch export hands over every card cut from one long note in a single click. A share link stores the content instead of a flattened picture, so whoever receives it can keep editing the card rather than ask you for the source file. Creating, previewing and switching themes stay free and unlimited with no paywall mid-edit; a 7-day pass or a monthly plan unlocks export, batch high-res output and removing the Cardify branding for commercial work. It is fully responsive, so the same flow works on phones and tablets.
