Markdown to Image Updates: Clearer export actions & in-article blog ads

Version: v3.2.1 Date: August 1, 2026

A small release focused on making the interface say what it does — export buttons now read as the primary action, and you're told plainly when an export carries a watermark.

🎯 Export buttons read as the primary action

  • Clear hierarchy: Save image, Save PDF and Save DOCX now use the primary button treatment across every tool. Previously they shared one outline style with Import, URL and Clear, so the main action of the page looked identical to clearing your work.
  • Consistent across tools: The same treatment now applies to the converter, code, Mermaid, formula, HTML and table tools.

💧 Watermark status you can actually see

  • Told, not hidden: When an export includes the watermark, a short notice appears afterwards with a direct link to remove it. Previously the only way to discover this was to open export settings and find a toggle that was off by default.
  • Nothing interrupts you: The notice appears after the export completes and can be dismissed. Paid plans and watermark-free exports never see it.

📰 In-article ads on blog posts

  • Placed at section breaks: Blog articles now carry up to two in-article ads, positioned above a section heading rather than dropped into the middle of a paragraph.
  • Long reads only: Short posts get no in-article ad, and ads are kept clear of code blocks and away from the top of the article.
