Markdown to Image Updates: Export presets, custom CSS, advanced PDF & API rate limiting

Version: v3.2.0 Date: June 8, 2026

A big update focused on giving you precise control over exports — and bringing the same discipline to our public API. Save your settings as presets, drop in your own CSS, fine-tune PDF output, and rely on predictable, plan-based API limits.

📐 Export presets & preferences

  • Save once, reuse anywhere: Bundle your export settings — theme, font, width, quality, format and more — into a named preset and apply it in one click.
  • Pick up where you left off: Set a default preset, and the editor restores your last-used settings automatically the next time you open it.
  • Across the tools: Presets work on the main converter and batch export. Named, reusable presets are available on the Creator plan and up.

🎨 Custom CSS

  • Bring your own styles: Pro accounts can inject custom CSS to fine-tune the rendered output, mirrored live in the preview as you type.
  • Page-break control: New break-before support lets you decide exactly where content splits when exporting to PDF.

📄 Advanced PDF settings

  • Print-ready output: Configure headers and footers, margins, paper size and orientation before exporting to PDF.
  • Page-count guardrail: A pre-flight check flags oversized output before you wait on it. Advanced PDF options are a Pro feature.

🃏 Smarter card batch export

  • One batch, one export: Card ZIP export now follows the same watermark rules as single images — a whole batch counts as a single export, not per card.
  • Consistent watermark logic: Paid plans export watermark-free without limit; free accounts draw on their available allowance; anonymous or used-up exports keep the watermark across the entire batch.
  • Clearer outcomes: Plain messaging when an export hits a limit or a render fails — the old per-card credit prompts are gone.

🚦 API rate limiting

  • Per-minute limits by plan: The public image API (POST /api/v1/images/generate) now enforces a per-minute rate limit — Free 10, Creator 20, Pro 60, Automation 300, Enterprise unlimited.
  • Standard headers: Every response carries X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset; over-limit calls return 429 with Retry-After.
  • Fail-open: If the rate-limit store is briefly unavailable, legitimate requests are never blocked.

✨ Unified tool headers

  • Every tool page now shares one branded header, so the layout reads consistently as you move between converters.
