Pinterest Pin Preview — See Your Pin Before You Publish
Pinterest Pin Preview is a 100% client-side tool that renders a draft pin as it appears on Pinterest, both inside the masonry feed (image, hover Save button, title and pinner beneath) and as a full close-up detail card with the title, description, profile and board. The user uploads a pin image and types the copy; a pure engine (pinterestPinEngine.ts) enforces Pinterest’s real 2026 limits, audits the image aspect ratio and formats the render on Pinterest’s light theme. It is a design mockup — it does not log in, fetch anything, or post to Pinterest.
- Two renders: masonry feed and close-up detail card
- Recommended pin ratio is 2:3 (1000×1500); 1:1 and long 1:2.1 supported
- Runs entirely in the browser — image is a local data URL, nothing uploaded
- Exports the render as a PNG via html2canvas
