Use Base64 wisely
Base64 is ideal for text-only APIs, small embedded assets, test fixtures, and portable documents. It increases payload size, so external files are usually better for large public assets.
Frequently asked questions
Will every Markdown renderer show the image?
No. GitHub and some platforms block Data URLs in Markdown. Verify your renderer before publishing.
What syntax is generated?
Standard Markdown image syntax  with the full Data URL embedded.
When should I use Base64 for embedded Markdown images?
Use it when a text-only channel or API must carry binary data, or when a small embedded Markdown images asset needs to live inside a self-contained document. Prefer separate files for large, cacheable public assets.
