FAQ

Does this send my source to a backend or AI service?

No. These P1 preview tools run locally in the browser for the supported parser path.

Is the preview a full production runtime?

No. It is a focused preview and debugging surface for common cases. Keep your browser, runtime, or production parser as the final authority.

Aperçu d’image Base64 is part of the DiagramPreview script and visual source preview toolbox.

It helps you close the gap between text generated by AI or copied from a project and the visual output that teammates actually review.

Use it as a quick validation step before turning snippets into docs, tickets, blog posts, or production examples.

Demo: preview a Base64 data URL

Base64 image previews help verify MIME type, dimensions, and visual content before embedding images in Markdown, CSS, HTML, or JSON payloads.

  • Confirm the data URL prefix matches the image type.
  • Check file size because Base64 increases payload size.
  • Preview SVG data URLs carefully when source is untrusted.

Publishing checklist: embedded images have tradeoffs

Base64 images are convenient for portability but can hurt caching and readability. Use them when a tiny self-contained asset is worth the cost.

  • Prefer external files for large screenshots.
  • Use Base64 for tiny icons or single-file demos.
  • Avoid embedding private images in shareable Markdown.
Good: 1KB icon in standalone HTML
Bad: 400KB screenshot in every page

Checklist de revue pour Aperçu d’image Base64

Utilisez Aperçu d’image Base64 pour inspecter visuellement une source avant documentation, note de PR, post-mortem ou transfert. Preview Base64 image strings and data URLs with MIME type and size analysis.

Limites et dépannage

Si l'aperçu échoue, réduisez l'entrée au plus petit exemple complet, validez la syntaxe puis réajoutez les sections.

Considérez l'aperçu comme une surface de revue, pas comme une source de vérité. Les résultats critiques doivent être validés.
