Convert SVG to Base64

Sanitize SVG markup and encode its UTF-8 bytes as raw Base64 or a complete image Data URI locally.

Scripts, foreignObject, event handlers and external references are removed before preview or conversion.

How it works

  1. Select an SVG and inspect the sanitized preview.
  2. Choose raw Base64 or Data URI.
  3. Convert the sanitized markup.
  4. Copy the result for your controlled development workflow.

Practical example

Data URI mode produces data:image/svg+xml;base64,... so the sanitized graphic can be used as an image source without a separate file request.

Formula and explanation

Base64 does not rasterize the vector: it encodes the sanitized SVG text as UTF-8 bytes. Decoding recovers vector markup and its scalability.

A Data URI includes the image MIME prefix; raw Base64 contains only encoded bytes. Embedding grows size by about one third and can reduce cache efficiency, so it is most useful for small self-contained assets.

Active elements and external references are removed before encoding. This is not encryption, and anyone with the Base64 can decode the SVG.

Frequently asked questions

Does Base64 make SVG safer?

No. Encoding is not a security boundary, which is why this tool sanitizes the markup before encoding.

Does the SVG remain scalable?

Yes. Base64 contains the vector XML, not a bitmap.

Should I use raw Base64 or Data URI?

Use Data URI directly in an image source; use raw Base64 when an API already knows the MIME type.
