Frequently Asked Questions

Base64 is a method to convert binary image data into a text string. This string can be embedded directly into HTML, CSS, or Markdown files using the data: URI scheme, eliminating separate image file requests.

It makes your markdown document self-contained. No external image links are needed, which is perfect for offline documents, emails, or note‑taking apps that support data URIs.

Base64-encoded images are about 33% larger than the original binary file. Embedding large images can bloat the document size, slow down rendering, and increase email weight. They also cannot be cached separately by browsers.

Generally, keep embedded images under 10–20 KB of Base64 text (≈ 7–15 KB binary). Icons, logos, or small decorative graphics work best. This tool warns you when the output exceeds 50 KB.

Yes. By setting a smaller width/height, the tool regenerates the image at that resolution, which often drastically reduces the resulting Base64 string. This is the easiest way to keep your embedded images light.

SVG is already text-based, so you can often embed it directly without Base64. However, this tool can still encode SVG to a data URI if needed.
